It enables running graphical X11 applications on a remote server and displaying their interfaces directly within the web browser. + +## Architecture + +The system follows a distributed server-client model where the browser itself acts as the X11 server. + +### 1. X11 Server (Go/WASM) +The core logic is implemented in Go and compiled to WebAssembly (WASM). +* **Protocol Handling:** Manages the X11 wire protocol, parsing incoming requests from clients and serializing replies, events, and errors. +* **State Management:** Maintains the authoritative state of windows, graphics contexts (GCs), properties, atoms, and resource allocations. +* **Event Routing:** Distributes input events (mouse, keyboard) to the correct clients and windows based on focus and grabs. +* **Abstraction:** Communicates with the rendering layer via the `X11FrontendAPI` interface, ensuring the core logic remains platform-independent. + +### 2. Frontend Renderer (HTML5 Canvas) +The rendering layer is implemented as a Go-WASM bridge to the browser's DOM. +* **Canvas Windows:** Each top-level X11 window is represented by an HTML5 `` element. +* **WASM-JS Bridge:** Uses `syscall/js` to translate Go drawing commands into high-performance JavaScript Canvas API calls. +* **Window Manager:** A lightweight internal window manager handles decorations (title bars, close buttons), dragging, and resizing for top-level windows. + +### 3. SSH Integration +X11 traffic is forwarded over standard SSH channels. +* **Forwarding:** When the `-X` flag is used, `sshterm` requests X11 forwarding from the remote server (`x11-req`). +* **Channel Management:** The application listens for incoming X11 channels and pipes them directly into the internal X11 server instance. + +--- + +## Core Components + +### `x11Server` (`go/internal/x11/x11.go`) +The central engine that coordinates client connections and resource management. It handles the initial handshake (supporting both Big and Little Endian) and dispatches opcodes to their respective handlers. + +### `wire` Package (`go/internal/x11/wire/`) +An exhaustive definition of the X11 protocol. It contains structs and serialization logic for over 100 requests, replies, events, and errors. It ensures strict protocol compliance and robust input validation. + +### `X11FrontendAPI` +A decoupled interface defining all visual and interactive operations: +* **Drawing:** `PolyLine`, `PolyFillRectangle`, `FillPoly`, `PolyArc`, `PutImage`, `ImageText8/16`, etc. +* **Windowing:** `CreateWindow`, `MapWindow`, `ConfigureWindow`, `SetWindowCursor`. +* **Resources:** `CreatePixmap`, `CreateGC`, `OpenFont`. +* **Interaction:** `GrabPointer`, `GrabKeyboard`, `AllowEvents`. + +--- + +## Rendering Engine + +### Logical Operations +X11 defines 16 logical functions for drawing (`GXcopy`, `GXxor`, `GXand`, etc.). `sshterm` uses a dual-path approach: +* **Native Path:** Common operations like `GXcopy` and `GXxor` are mapped to Canvas `globalCompositeOperation` (e.g., `source-over`, `difference`) for hardware-accelerated performance. +* **Software Path:** For complex operations not supported by Canvas, an optimized software renderer performs bitwise manipulation on `Uint32Array` views of the pixel data. + +### Optimizations +* **Dirty Region Tracking:** The server tracks modified areas of windows to minimize redrawing and data transfer. +* **Bulk Memory Copy:** `PutImage` avoids per-pixel Go-to-JS calls by passing raw byte slices and using `Uint8ClampedArray.set()` for high-speed transfers. +* **Throttling:** High-frequency events like `mousemove` are throttled to 60FPS to prevent flooding the WASM bridge. + +--- + +## Input & Interaction + +### Grabs and Synchronization +* **Active Grabs:** Implements `GrabPointer` and `GrabKeyboard` using the browser's `setPointerCapture` API. This ensures that menus and popups correctly capture interaction even outside their window boundaries. +* **Event Queuing:** To support `AllowEvents` and synchronous grabs, the server maintains internal event queues. During a synchronous grab, events are buffered and only released when the client explicitly requests them, preventing race conditions in modal dialogs. + +### Fonts +X11 Logical Font Descriptions (XLFD) are mapped to modern CSS web fonts. The server generates accurate font metrics (ascent, descent, character widths) to ensure clients can correctly calculate their layout. + +### Clipboard +X11 selections (`CLIPBOARD`, `PRIMARY`) are integrated with the browser's `navigator.clipboard` API. This allows seamless copy-paste between remote graphical applications and local browser/OS applications. + +--- + +## Extensions Support + +* **BigRequests:** Fully supported, allowing for requests larger than 256KB. +* **XInput / XInput2:** Implements device state queries, extended event masks, and raw motion events. +* **MIT-SHM:** Reported as unsupported, forcing clients to fall back to standard `PutImage`/`GetImage` paths which are optimized within the WASM environment. + +--- + +## Security + +* **MIT-MAGIC-COOKIE-1:** Standard X11 authentication is implemented to verify connections. +* **Isolation:** The X11 server runs entirely within the browser's security sandbox. It has no access to the local filesystem or network beyond what the SSH session and browser APIs allow. + +--- + +## Testing Strategy + +### 1. Unit Tests +Located in `go/internal/x11/`, these tests verify protocol parsing, resource state, and logic. They use a mock frontend to assert that X11 requests result in the expected internal state changes. + +### 2. Visual Tests +Automated WASM-based tests (`visual_test.go`) that render primitives to a canvas and verify the result by comparing pixel data against expected values. This ensures high-fidelity rendering for all GC functions and drawing modes. + +### 3. Integration Tests +Headless browser tests (`tests/run-headless-tests.sh`) use `chromedp` to drive the full application. They connect to a mock SSH server, launch real X11 applications (like `xterm` or `xeyes`), and verify that windows appear and respond to injected input correctly. diff --git a/build.sh b/build.sh index 63f4b92..07a5cff 100755 --- a/build.sh +++ b/build.sh @@ -1,12 +1,16 @@ #!/bin/bash -e cd $(dirname $0) + +mkdir -p output +exec &> >(tee output/build.log) + if [[ ! -f docroot/xterm.mjs ]]; then echo "Updating xtermjs..." ./xterm/update.sh fi echo "Updating ssh.wasm..." -./go/build.sh +./go/build.sh "$@" echo "Files in ./docroot/" ls ./docroot/ echo "Done" diff --git a/docroot/main.mjs b/docroot/main.mjs index 8cfa86e..236b32c 100644 --- a/docroot/main.mjs +++ b/docroot/main.mjs @@ -25,6 +25,4 @@ import { TabManager } from './ssh.mjs'; -window.addEventListener('load', () => { - new TabManager(document.getElementById('terminal')); -}); +new TabManager(document.getElementById('terminal')); diff --git a/docroot/ssh.mjs b/docroot/ssh.mjs index 994d962..6f1f3f9 100644 --- a/docroot/ssh.mjs +++ b/docroot/ssh.mjs @@ -29,6 +29,9 @@ import { Terminal, FitAddon } from './xterm.mjs'; function isTest() { return window.location.pathname.indexOf('tests.html') !== -1; } +function isX11Test() { + return window.location.pathname.indexOf('tests.html') !== -1 && window.location.search.indexOf('x11') !== -1; +} class TerminalManager { constructor(elem, setTitle, onBell) { @@ -183,18 +186,22 @@ export class TabManager { this.selectScreen(b.id); const term = terminalManager.getTerm(); - const cfg = await fetch('config.json') + const configFile = isX11Test() ?

Implementation + +This directory contains the implementation of the server-side X11 forwarding protocol for sshterm. The code is structured to support two different architectures: a WebAssembly (wasm) target that runs in the browser, and a standard non-wasm target used for testing. + +## Target Architecture Overview + +The core X11 server logic is designed to be platform-independent. It communicates with a frontend via the `X11FrontendAPI` interface. The actual implementation of this frontend is the only part of the code that is architecture-dependent. + +- The core server logic resides in `x11.go`. +- The `X11FrontendAPI` interface is defined in `x11.go`. +- The `newX11Frontend` function, which returns an `X11FrontendAPI` implementation, is architecture-dependent. +- For the **wasm** build (in-browser), the frontend implementation in `x11_frontend_wasm.go` communicates with JavaScript to handle rendering. This is further split into `x11_frontend_wasm_debug.go` and `x11_frontend_wasm_nodebug.go` to manage debug logging. +- For **non-wasm** builds (used for tests), a mock frontend in `x11_frontend_mock.go` is used to simulate the frontend behavior. + +### Build Tags + +Go build tags are used to manage the different build configurations. + +- `//go:build x11`: This is the main build tag for the package. Most files have this tag, so the X11 forwarding code is only enabled when this tag is used. +- `//go:build !x11`: The `nox11.go` file uses this tag to provide a stub implementation when X11 support is disabled. +- `//go:build wasm` and `//go:build !wasm`: These tags are used to separate the wasm and non-wasm (mock) implementations of the `X11FrontendAPI`. They are always used in combination with the `x11` tag. +- `//go:build debug` and `//go:build !debug`: These tags control the inclusion of debugging-related code. + +## File Structure + +- **`x11.go`**: Contains the core, architecture-independent data structures (`x11Server`, `window`, request/setup structs), the `X11FrontendAPI` interface, the `HandleX11Forwarding` function (which sets up the channel handling), and the `x11Server` methods (`serve`, `handshake`, `handleRequest`). + +- **`client.go`**: Manages the state of a single connected X11 client, including their windows, resources, and message queue. + +- **`wire/`**: A sub-package containing Go representations of the X11 wire protocol. It defines structs for requests, replies, events, and errors, and handles the low-level parsing and serialization of binary X11 messages. + +- **`request_handlers.go`**: Contains the handler functions for the various X11 requests (e.g., `handleCreateWindow`, `handlePutImage`). These functions are called by the main server loop in `x11.go` to process incoming client requests. + +- **`xinput.go`**: Implements support for the XInput extension, which allows for more advanced handling of input devices beyond the core keyboard and pointer. + +- **`fonts.go`**, **`keymap.go`**, **`colorname.go`**: These files provide helper functionality for managing X11 fonts, keyboard mappings, and named colors. + +- **`x11_frontend_wasm.go`**: (`//go:build wasm`) The `wasm` implementation of the `X11FrontendAPI` and the `newX11Frontend` function for wasm builds. It acts as a bridge to the browser's JavaScript environment to perform rendering tasks. + +- **`x11_frontend_mock.go`**: (`//go:build !wasm`) A mock implementation of the `X11FrontendAPI` and the `newX11Frontend` function for non-wasm builds. It records calls made to its methods, allowing tests to verify server behavior without a graphical environment. + +- **`*_test.go`**: Various test files for the package. +- **`testing_helpers_test.go`**: Provides common testing utilities, such as mock loggers and network connections, used across the test files. diff --git a/go/internal/x11/Xproto.h.txt b/go/internal/x11/Xproto.h.txt new file mode 100644 index 0000000..74193e2 --- /dev/null +++ b/go/internal/x11/Xproto.h.txt @@ -0,0 +1,2157 @@ +/* Definitions for the X window system used by server and c bindings */ + +/* + * This packet-construction scheme makes the following assumptions: + * + * 1.

Not all mechanisms are needed to build a particular user +interface. It is important to keep in mind that the protocol is intended to +provide mechanism, not policy. + +Robert W. Scheifler + +X Consortium, Inc. + +Chapter 1. Protocol Formats + +Table of Contents + +Request Format +Reply Format +Error Format +Event Format + +Request Format + +Every request contains an 8-bit major opcode and a 16-bit length field +expressed in units of four bytes. Every request consists of four bytes of a +header (containing the major opcode, the length field, and a data byte) +followed by zero or more additional bytes of data. The length field defines the +total length of the request, including the header. The length field in a +request must equal the minimum length required to contain the request. If the +specified length is smaller or larger than the required length, an error is +generated. Unused bytes in a request are not required to be zero. Major opcodes +128 through 255 are reserved for extensions. Extensions are intended to contain +multiple requests, so extension requests typically have an additional minor +opcode encoded in the second data byte in the request header. However, the +placement and interpretation of this minor opcode and of all other fields in +extension requests are not defined by the core protocol. Every request on a +given connection is implicitly assigned a sequence number, starting with one, +that is used in replies, errors, and events. + +Reply Format + +Every reply contains a 32-bit length field expressed in units of four bytes. +Every reply consists of 32 bytes followed by zero or more additional bytes of +data, as specified in the length field. Unused bytes within a reply are not +guaranteed to be zero. Every reply also contains the least significant 16 bits +of the sequence number of the corresponding request. + +Error Format + +Error reports are 32 bytes long. Every error includes an 8-bit error code. +Error codes 128 through 255 are reserved for extensions. Every error also +includes the major and minor opcodes of the failed request and the least +significant 16 bits of the sequence number of the request. For the following +errors (see section 4), the failing resource ID is also returned: Colormap, +Cursor, Drawable, Font, GContext, IDChoice, Pixmap and Window. For Atom errors, +the failing atom is returned. For Value errors, the failing value is returned. +Other core errors return no additional data. Unused bytes within an error are +not guaranteed to be zero. + +Event Format + +Events are 32 bytes long. Unused bytes within an event are not guaranteed to be +zero. Every event contains an 8-bit type code. The most significant bit in this +code is set if the event was generated from a SendEvent request. Event codes 64 +through 127 are reserved for extensions, although the core protocol does not +define a mechanism for selecting interest in such events. Every core event +(with the exception of KeymapNotify) also contains the least significant 16 +bits of the sequence number of the last request issued by the client that was +(or is currently being) processed by the server. + +Chapter 2. Syntactic Conventions + +The rest of this document uses the following syntactic conventions. + + ● The syntax {...} encloses a set of alternatives. + + ● The syntax [...] encloses a set of structure components. + + ● In general, TYPEs are in uppercase and AlternativeValues are capitalized. + + ● Requests in section 9 are described in the following format: + + RequestName + arg1: type1 + ... + argN: typeN + ▶ + result1: type1 + ... + resultM: typeM + + Errors: kind1, ..., kindK + + Description. + + If no ▶ is present in the description, then the request has no reply (it is + asynchronous), although errors may still be reported. If ▶+ is used, then + one or more replies can be generated for a single request. + + ● Events in section 11 are described in the following format: + + EventName + value1: type1 + ... + valueN: typeN + + Description. + +Chapter 3. Common Types + +┌────────────┬────────────────────────────────────────────────────────────────┐ +│Name │Value │ +├────────────┼────────────────────────────────────────────────────────────────┤ +│ │A type name of the form LISTofFOO means a counted list of │ +│ │elements of type FOO. The size of the length field may vary (it │ +│LISTofFOO │is not necessarily the same size as a FOO), and in some cases, │ +│ │it may be implicit. It is fully specified in Appendix B. Except │ +│ │where explicitly noted, zero-length lists are legal. │ +├────────────┼────────────────────────────────────────────────────────────────┤ +│ │The types BITMASK and LISTofVALUE are somewhat special. Various │ +│ │requests contain arguments of the form: │ +│ │ │ +│ │value-mask: BITMASK │ +│ │ │ +│ │value-list: LISTofVALUE │ +│ │ │ +│ │These are used to allow the client to specify a subset of a │ +│BITMASK │heterogeneous collection of optional arguments. The value-mask │ +│ │specifies which arguments are to be provided; each such argument│ +│LISTofVALUE │is assigned a unique bit position. The representation of the │ +│ │BITMASK will typically contain more bits than there are defined │ +│ │arguments.

+└────────────┴────────────────────────────────────────────────────────────────┘ + +The [x,y] coordinates of a RECTANGLE specify the upper-left corner. + +The primary interpretation of large

This corresponds to the JIS/ISO method of indexing +2-byte characters. It is expected that most large fonts will be defined with +2-byte matrix indexing. For large fonts constructed with linear indexing, a +CHAR2B can be interpreted as a 16-bit number by treating byte1 as the most +significant byte. This means that clients should always transmit such 16-bit +character values most significant byte first, as the server will never +byte-swap CHAR2B quantities. + +The length, format, and interpretation of a HOST address are specific to the +family (see ChangeHosts request). + +Chapter 4. Errors + +In general, when a request terminates with an error, the request has no side +effects (that is, there is no partial execution).

Keycodes lie in the inclusive +range [8,255]. A keycode value carries no intrinsic information, although +server implementors may attempt to encode geometry information (for example, +matrix) to be interpreted in a server-dependent fashion. The mapping between +keys and keycodes cannot be changed using the protocol. + +A KEYSYM is an encoding of a symbol on the cap of a key. The set of defined +KEYSYMs include the character sets Latin-1, Latin-2, Latin-3, Latin-4, Kana, +Arabic, Cyrillic, Greek, Tech, Special, Publish, APL, Hebrew, Thai, and Korean +as well as a set of symbols common on keyboards (Return, Help, Tab, and so on). +KEYSYMs with the most significant bit (of the 29 bits) set are reserved as +vendor-specific. + +A list of KEYSYMs is associated with each KEYCODE. The list is intended to +convey the set of symbols on the corresponding key. If the list (ignoring +trailing NoSymbol entries) is a single KEYSYM "K", then the list is treated as +if it were the list "K NoSymbol K NoSymbol". If the list (ignoring trailing +NoSymbol entries) is a pair of KEYSYMs "K1 K2", then the list is treated as if +it were the list "K1 K2 K1 K2". If the list (ignoring trailing NoSymbol +entries) is a triple of KEYSYMs "K1 K2 K3", then the list is treated as if it +were the list " K1 K2 K3 NoSymbol". When an explicit "void" element is desired +in the list, the value VoidSymbol can be used. + +The first four elements of the list are split into two groups of KEYSYMs. Group +1 contains the first and second KEYSYMs, Group 2 contains the third and fourth +KEYSYMs. Within each group, if the second element of the group is NoSymbol, +then the group should be treated as if the second element were the same as the +first element, except when the first element is an alphabetic KEYSYM "K" for +which both lowercase and uppercase forms are defined. In that case, the group +should be treated as if the first element were the lowercase form of "K" and +the second element were the uppercase form of "K". + +The standard rules for obtaining a KEYSYM from a KeyPress event make use of +only the Group 1 and Group 2 KEYSYMs; no interpretation of other KEYSYMs in the +list is defined. The modifier state determines which group to use. Switching +between groups is controlled by the KEYSYM named MODE SWITCH, by attaching that +KEYSYM to some KEYCODE and attaching that KEYCODE to any one of the modifiers +Mod1 through Mod5. This modifier is called the "group modifier". For any +KEYCODE, Group 1 is used when the group modifier is off, and Group 2 is used +when the group modifier is on. + +The Lock modifier is interpreted as CapsLock when the KEYSYM named CAPS LOCK is +attached to some KEYCODE and that KEYCODE is attached to the Lock modifier. The +Lock modifier is interpreted as ShiftLock when the KEYSYM named SHIFT LOCK is +attached to some KEYCODE and that KEYCODE is attached to the Lock modifier. If +the Lock modifier could be interpreted as both CapsLock and ShiftLock, the +CapsLock interpretation is used. + +The operation of "keypad" keys is controlled by the KEYSYM named NUM LOCK, by +attaching that KEYSYM to some KEYCODE and attaching that KEYCODE to any one of +the modifiers Mod1 through Mod5. This modifier is called the "numlock +modifier". The standard KEYSYMs with the prefix KEYPAD in their name are called +"keypad" KEYSYMs; these are KEYSYMS with numeric value in the hexadecimal range +#xFF80 to #xFFBD inclusive. In addition, vendor-specific KEYSYMS in the +hexadecimal range #x11000000 to #x1100FFFF are also keypad KEYSYMs. + +Within a group, the choice of KEYSYM is determined by applying the first rule +that is satisfied from the following list: + + ● The numlock modifier is on and the second KEYSYM is a keypad KEYSYM. In + this case, if the Shift modifier is on, or if the Lock modifier is on and + is interpreted as ShiftLock, then the first KEYSYM is used; otherwise, the + second KEYSYM is used. + + ● The Shift and Lock modifiers are both off. In this case, the first KEYSYM + is used. + + ● The Shift modifier is off, and the Lock modifier is on and is interpreted + as CapsLock. In this case, the first KEYSYM is used, but if that KEYSYM is + lowercase alphabetic, then the corresponding uppercase KEYSYM is used + instead. + + ● The Shift modifier is on, and the Lock modifier is on and is interpreted as + CapsLock. In this case, the second KEYSYM is used, but if that KEYSYM is + lowercase alphabetic, then the corresponding uppercase KEYSYM is used + instead. + + ● The Shift modifier is on, or the Lock modifier is on and is interpreted as + ShiftLock, or both. In this case, the second KEYSYM is used. + +The mapping between KEYCODEs and KEYSYMs is not used directly by the server; it +is merely stored for reading and writing by clients. + +Chapter 6. Pointers + +Buttons are always numbered starting with one. + +Chapter 7. Predefined Atoms + +Predefined atoms are not strictly necessary and may not be useful in all +environments, but they will eliminate many InternAtom requests in most +applications. Note that they are predefined only in the sense of having numeric +values, not in the sense of having required semantics. The core protocol +imposes no semantics on these names, but semantics are specified in other X +Window System standards, such as the Inter-Client Communication Conventions +Manual and the X Logical Font Description Conventions. + +The following names have predefined atom values. Note that uppercase and +lowercase matter. + +ARC ITALIC_ANGLE STRING +ATOM MAX_SPACE SUBSCRIPT_X +BITMAP MIN_SPACE SUBSCRIPT_Y +CAP_HEIGHT NORM_SPACE SUPERSCRIPT_X +CARDINAL NOTICE SUPERSCRIPT_Y +COLORMAP PIXMAP UNDERLINE_POSITION +COPYRIGHT POINT UNDERLINE_THICKNESS +CURSOR POINT_SIZE VISUALID +CUT_BUFFER0 PRIMARY WEIGHT +CUT_BUFFER1 QUAD_WIDTH WINDOW +CUT_BUFFER2 RECTANGLE WM_CLASS +CUT_BUFFER3 RESOLUTION WM_CLIENT_MACHINE +CUT_BUFFER4 RESOURCE_MANAGER WM_COMMAND +CUT_BUFFER5 RGB_BEST_MAP WM_HINTS +CUT_BUFFER6 RGB_BLUE_MAP WM_ICON_NAME +CUT_BUFFER7 RGB_COLOR_MAP WM_ICON_SIZE +DRAWABLE RGB_DEFAULT_MAP WM_NAME +END_SPACE RGB_GRAY_MAP WM_NORMAL_HINTS +FAMILY_NAME RGB_GREEN_MAP WM_SIZE_HINTS +FONT RGB_RED_MAP WM_TRANSIENT_FOR +FONT_NAME SECONDARY WM_ZOOM_HINTS +FULL_NAME STRIKEOUT_ASCENT X_HEIGHT +INTEGER STRIKEOUT_DESCENT   + +To avoid conflicts with possible future names for which semantics might be +imposed (either at the protocol level or in terms of higher level user +interface models), names beginning with an underscore should be used for atoms +that are private to a particular vendor or organization. To guarantee no +conflicts between vendors and organizations, additional prefixes need to be +used. However, the protocol does not define the mechanism for choosing such +prefixes. For names private to a single application or end user but stored in +globally accessible locations, it is suggested that two leading underscores be +used to avoid conflicts with other names. + +Chapter 8. Connection Setup + +Table of Contents + +Connection Initiation +Server Response +Server Information +Screen Information +Visual Information + +For remote clients, the X protocol can be built on top of any reliable byte +stream. + +Connection Initiation + +The client must send an initial byte of data to identify the byte order to be +employed. The value of the byte must be octal 102 or 154. The value 102 (ASCII +uppercase B) means values are transmitted most significant byte first, and +value 154 (ASCII lowercase l) means values are transmitted least significant +byte first. Except where explicitly noted in the protocol, all 16-bit and +32-bit quantities sent by the client must be transmitted with this byte order, +and all 16-bit and 32-bit quantities returned by the server will be transmitted +with this byte order. + +Following the byte-order byte, the client sends the following information at +connection setup: + + protocol-major-version: CARD16 + + protocol-minor-version: CARD16 + + authorization-protocol-name: STRING8 + + authorization-protocol-data: STRING8 + +The version numbers indicate what version of the protocol the client expects +the server to implement. + +The authorization name indicates what authorization (and authentication) +protocol the client expects the server to use, and the data is specific to that +protocol. Specification of valid authorization mechanisms is not part of the +core X protocol. A server that does not implement the protocol the client +expects or that only implements the host-based mechanism may simply ignore this +information. If both name and data strings are empty, this is to be interpreted +as "no explicit authorization." + +Server Response + +The client receives the following information at connection setup: + + ● success: { Failed, Success, Authenticate} + +The client receives the following additional data if the returned success value +is Failed, and the connection is not successfully established: + + protocol-major-version: CARD16 + + protocol-minor-version: CARD16 + + reason: STRING8 + +The client receives the following additional data if the returned success value +is Authenticate, and further authentication negotiation is required: + + reason: STRING8 + +The contents of the reason string are specific to the authorization protocol in +use.

In general, the major version would increment for +incompatible changes, and the minor version would increment for small upward +compatible changes. Barring changes, the major version will be 11, and the +minor version will be 0. The protocol version numbers returned indicate the +protocol the server actually supports. This might not equal the version sent by +the client. The server can (but need not) refuse connections from clients that +offer a different version than the server supports. A server can (but need not) +support more than one version simultaneously. + +The vendor string gives some identification of the owner of the server +implementation. The vendor controls the semantics of the release number. + +The resource-id-mask contains a single contiguous set of bits (at least 18). +The client allocates resource IDs for types WINDOW, PIXMAP, CURSOR, FONT, +GCONTEXT, and COLORMAP by choosing a value with only some subset of these bits +set and ORing it with resource-id-base. Only values constructed in this way can +be used to name newly created resources over this connection. Resource IDs +never have the top three bits set. The client is not restricted to linear or +contiguous allocation of resource IDs. Once an ID has been freed, it can be +reused. An ID must be unique with respect to the IDs of all other resources, +not just other resources of the same type. However, note that the value spaces +of resource identifiers, atoms, visualids, and keysyms are distinguished by +context, and as such, are not required to be disjoint; for example, a given +numeric value might be both a valid window ID, a valid atom, and a valid +keysym. + +Although the server is in general responsible for byte-swapping data to match +the client, images are always transmitted and received in formats (including +byte order) specified by the server. The byte order for images is given by +image-byte-order and applies to each scanline unit in XY format (bitmap format) +and to each pixel value in Z format. + +A bitmap is represented in scanline order. Each scanline is padded to a +multiple of bits as given by bitmap-scanline-pad. The pad bits are of arbitrary +value. The scanline is quantized in multiples of bits as given by +bitmap-scanline-unit. The bitmap-scanline-unit is always less than or equal to +the bitmap-scanline-pad. Within each unit, the leftmost bit in the bitmap is +either the least significant or most significant bit in the unit, as given by +bitmap-bit-order. If a pixmap is represented in XY format, each plane is +represented as a bitmap, and the planes appear from most significant to least +significant in bit order with no padding between planes. + +Pixmap-formats contains one entry for each depth value. The entry describes the +Z format used to represent images of that depth. An entry for a depth is +included if any screen supports that depth, and all screens supporting that +depth must support only that Z format for that depth. In Z format, the pixels +are in scanline order, left to right within a scanline. The number of bits used +to hold each pixel is given by bits-per-pixel. Bits-per-pixel may be larger +than strictly required by the depth, in which case the least significant bits +are used to hold the pixmap data, and the values of the unused high-order bits +are undefined. When the bits-per-pixel is 4, the order of nibbles in the byte +is the same as the image byte-order. When the bits-per-pixel is 1, the format +is identical for bitmap format. Each scanline is padded to a multiple of bits +as given by scanline-pad. When bits-per-pixel is 1, this will be identical to +bitmap-scanline-pad. + +How a pointing device roams the screens is up to the server implementation and +is transparent to the protocol. No geometry is defined among screens. + +The server may retain the recent history of pointer motion and do so to a finer +granularity than is reported by MotionNotify events. The GetMotionEvents +request makes such history available. The motion-buffer-size gives the +approximate maximum number of elements in the history buffer. + +Maximum-request-length specifies the maximum length of a request accepted by +the server, in 4-byte units. That is, length is the maximum value that can +appear in the length field of a request. Requests larger than this maximum +generate a Length error, and the server will read and simply discard the entire +request. Maximum-request-length will always be at least 4096 (that is, requests +of length up to and including 16384 bytes will be accepted by all servers). + +Min-keycode and max-keycode specify the smallest and largest keycode values +transmitted by the server. Min-keycode is never less than 8, and max-keycode is +never greater than 255. Not all keycodes in this range are required to have +corresponding keys. + +Screen Information + +The information that applies per screen is: + +The allowed-depths specifies what pixmap and window depths are supported. +Pixmaps are supported for each depth listed, and windows of that depth are +supported if at least one visual type is listed for the depth. A pixmap depth +of one is always supported and listed, but windows of depth one might not be +supported. A depth of zero is never listed, but zero-depth InputOnly windows +are always supported. + +Root-depth and root-visual specify the depth and visual type of the root +window. Width-in-pixels and height-in-pixels specify the size of the root +window (which cannot be changed). The class of the root window is always +InputOutput. Width-in-millimeters and height-in-millimeters can be used to +determine the physical size and the aspect ratio. + +The default-colormap is the one initially associated with the root window. +Clients with minimal color requirements creating windows of the same depth as +the root may want to allocate from this map by default. + +Black-pixel and white-pixel can be used in implementing a monochrome +application. These pixel values are for permanently allocated entries in the +default-colormap. The actual RGB values may be settable on some screens and, in +any case, may not actually be black and white. The names are intended to convey +the expected relative intensity of the colors. + +The border of the root window is initially a pixmap filled with the +black-pixel. The initial background of the root window is a pixmap filled with +some unspecified two-color pattern using black-pixel and white-pixel. + +Min-installed-maps specifies the number of maps that can be guaranteed to be +installed simultaneously (with InstallColormap), regardless of the number of +entries allocated in each map. Max-installed-maps specifies the maximum number +of maps that might possibly be installed simultaneously, depending on their +allocations. Multiple static-visual colormaps with identical contents but +differing in resource ID should be considered as a single map for the purposes +of this number. For the typical case of a single hardware colormap, both values +will be 1. + +Backing-stores indicates when the server supports backing stores for this +screen, although it may be storage limited in the number of windows it can +support at once. If save-unders is True, the server can support the save-under +mode in CreateWindow and ChangeWindowAttributes, although again it may be +storage limited. + +The current-input-events is what GetWindowAttributes would return for the +all-event-masks for the root window. + +Visual Information + +The information that applies per visual-type is: + +A given visual type might be listed for more than one depth or for more than +one screen. + +For PseudoColor, a pixel value indexes a colormap to produce independent RGB +values; the RGB values can be changed dynamically. GrayScale is treated in the +same way as PseudoColor except which primary drives the screen is undefined; +thus, the client should always store the same value for red, green, and blue in +colormaps. For DirectColor, a pixel value is decomposed into separate RGB +subfields, and each subfield separately indexes the colormap for the +corresponding value. The RGB values can be changed dynamically. TrueColor is +treated in the same way as DirectColor except the colormap has predefined +read-only RGB values. These values are server-dependent but provide linear or +near-linear increasing ramps in each primary. StaticColor is treated in the +same way as PseudoColor except the colormap has predefined read-only RGB +values, which are server-dependent. StaticGray is treated in the same way as +StaticColor except the red, green, and blue values are equal for any single +pixel value, resulting in shades of gray. StaticGray with a two-entry colormap +can be thought of as monochrome. + +The red-mask, green-mask, and blue-mask are only defined for DirectColor and +TrueColor. Each has one contiguous set of bits set to 1 with no intersections. +Usually each mask has the same number of bits set to 1. + +The bits-per-rgb-value specifies the log base 2 of the number of distinct color +intensity values (individually) of red, green, and blue. This number need not +bear any relation to the number of colormap entries. Actual RGB values are +always passed in the protocol within a 16-bit spectrum, with 0 being minimum +intensity and 65535 being the maximum intensity. On hardware that provides a +linear zero-based intensity ramp, the following relationship exists: + + hw-intensity = protocol-intensity / (65536 / total-hw-intensities) + +Colormap entries are indexed from 0. The colormap-entries defines the number of +available colormap entries in a newly created colormap. For DirectColor and +TrueColor, this will usually be 2 to the power of the maximum number of bits +set to 1 in red-mask, green-mask, and blue-mask. + +Chapter 9. Requests + +Table of Contents + +CreateWindow +ChangeWindowAttributes +GetWindowAttributes +DestroyWindow +DestroySubwindows +ChangeSaveSet +ReparentWindow +MapWindow +MapSubwindows +UnmapWindow +UnmapSubwindows +ConfigureWindow +CirculateWindow +GetGeometry +QueryTree +InternAtom +GetAtomName +ChangeProperty +DeleteProperty +GetProperty +RotateProperties +ListProperties +SetSelectionOwner +GetSelectionOwner +ConvertSelection +SendEvent +GrabPointer +UngrabPointer +GrabButton +UngrabButton +ChangeActivePointerGrab +GrabKeyboard +UngrabKeyboard +GrabKey +UngrabKey +AllowEvents +GrabServer +UngrabServer +QueryPointer +GetMotionEvents +TranslateCoordinates +WarpPointer +SetInputFocus +GetInputFocus +QueryKeymap +OpenFont +CloseFont +QueryFont +QueryTextExtents +ListFonts +ListFontsWithInfo +SetFontPath +GetFontPath +CreatePixmap +FreePixmap +CreateGC +ChangeGC +CopyGC +SetDashes +SetClipRectangles +FreeGC +ClearArea +CopyArea +CopyPlane +PolyPoint +PolyLine +PolySegment +PolyRectangle +PolyArc +FillPoly +PolyFillRectangle +PolyFillArc +PutImage +GetImage +PolyText8 +PolyText16 +ImageText8 +ImageText16 +CreateColormap +FreeColormap +CopyColormapAndFree +InstallColormap +UninstallColormap +ListInstalledColormaps +AllocColor +AllocNamedColor +AllocColorCells +AllocColorPlanes +FreeColors +StoreColors +StoreNamedColor +QueryColors +LookupColor +CreateCursor +CreateGlyphCursor +FreeCursor +RecolorCursor +QueryBestSize +QueryExtension +ListExtensions +SetModifierMapping +GetModifierMapping +ChangeKeyboardMapping +GetKeyboardMapping +ChangeKeyboardControl +GetKeyboardControl +Bell +SetPointerMapping +GetPointerMapping +ChangePointerControl +GetPointerControl +SetScreenSaver +GetScreenSaver +ForceScreenSaver +ChangeHosts +ListHosts +SetAccessControl +SetCloseDownMode +KillClient +NoOperation + +CreateWindow + +wid, parent: WINDOW +class: { InputOutput, InputOnly, CopyFromParent} +depth: CARD8 +visual: VISUALID or CopyFromParent +x, y: INT16 +width, height, border-width: CARD16 +value-mask: BITMASK +value-list: LISTofVALUE +Errors: Alloc, Colormap, Cursor, IDChoice, Match, Pixmap, Value, Window + +This request creates an unmapped window and assigns the identifier wid to it. + +A class of CopyFromParent means the class is taken from the parent.

Range checking is not +performed on the background-pixel value; it is simply truncated to the +appropriate number of bits. For a ParentRelative background, the background +tile origin always aligns with the parent's background tile origin.

If the background is None, the previous screen +contents from other windows of the same depth as the window are simply left in +place if the contents come from the parent of the window or an inferior of the +parent; otherwise, the initial contents of the exposed regions are undefined. +Exposure events are then generated for the regions, even if the background is +None. + +The border tile origin is always the same as the background tile origin. If +border-pixmap is given, it overrides the default border-pixmap. The border +pixmap and the window must have the same root and the same depth (or a Match +error results). Any size pixmap can be used, although some sizes may be faster +than others. If CopyFromParent is given, the parent's border pixmap is copied +(subsequent changes to the parent's border attribute do not affect the child), +but the window must have the same depth as the parent (or a Match error +results).

If +border-pixel is given, it overrides the default border-pixmap and any +border-pixmap given explicitly, and a pixmap of undefined size filled with +border-pixel is used for the border. Range checking is not performed on the +border-pixel value; it is simply truncated to the appropriate number of bits. + +Output to a window is always clipped to the inside of the window, so that the +border is never affected. + +The bit-gravity defines which region of the window should be retained if the +window is resized, and win-gravity defines how the window should be +repositioned if the parent is resized (see ConfigureWindow request). + +A backing-store of WhenMapped advises the server that maintaining contents of +obscured regions when the window is mapped would be beneficial. A backing-store +of Always advises the server that maintaining contents even when the window is +unmapped would be beneficial. In this case, the server may generate an exposure +event when the window is created. A value of NotUseful advises the server that +maintaining contents is unnecessary, although a server may still choose to +maintain contents while the window is mapped. Note that if the server maintains +contents, then the server should maintain complete contents not just the region +within the parent boundaries, even if the window is larger than its parent. +While the server maintains contents, exposure events will not normally be +generated, but the server may stop maintaining contents at any time. + +If save-under is True, the server is advised that when this window is mapped, +saving the contents of windows it obscures would be beneficial. + +When the contents of obscured regions of a window are being maintained, regions +obscured by noninferior windows are included in the destination (and source, +when the window is the source) of graphics requests, but regions obscured by +inferior windows are not included. + +The backing-planes indicates (with bits set to 1) which bit planes of the +window hold dynamic data that must be preserved in backing-stores and during +save-unders. The backing-pixel specifies what value to use in planes not +covered by backing-planes. The server is free to save only the specified bit +planes in the backing-store or save-under and regenerate the remaining planes +with the specified pixel value. Any bits beyond the specified depth of the +window in these values are simply ignored. + +The event-mask defines which events the client is interested in for this window +(or for some event types, inferiors of the window). The do-not-propagate-mask +defines which events should not be propagated to ancestor windows when no +client has the event type selected in this window. + +The override-redirect specifies whether map and configure requests on this +window should override a SubstructureRedirect on the parent, typically to +inform a window manager not to tamper with the window. + +The colormap specifies the colormap that best reflects the true colors of the +window. Servers capable of supporting multiple hardware colormaps may use this +information, and window managers may use it for InstallColormap requests. The +colormap must have the same visual type and root as the window (or a Match +error results). If CopyFromParent is specified, the parent's colormap is copied +(subsequent changes to the parent's colormap attribute do not affect the +child). However, the window must have the same visual type as the parent (or a +Match error results), and the parent must not have a colormap of None (or a +Match error results). For an explanation of None, see FreeColormap request. The +colormap is copied by sharing the colormap object between the child and the +parent, not by making a complete copy of the colormap contents. + +If a cursor is specified, it will be used whenever the pointer is in the +window. If None is specified, the parent's cursor will be used when the pointer +is in the window, and any change in the parent's cursor will cause an immediate +change in the displayed cursor. + +This request generates a CreateNotify event. + +The background and border pixmaps and the cursor may be freed immediately if no +further explicit references to them are to be made. + +Subsequent drawing into the background or border pixmap has an undefined effect +on the window state.

Setting a new border, whether by +border-pixel or border-pixmap, overrides any previous border. + +Changing the background does not cause the window contents to be changed. +Setting the border or changing the background such that the border tile origin +changes causes the border to be repainted. Changing the background of a root +window to None or ParentRelative restores the default background pixmap. +Changing the border of a root window to CopyFromParent restores the default +border pixmap. + +Changing the win-gravity does not affect the current position of the window. + +Changing the backing-store of an obscured window to WhenMapped or Always or +changing the backing-planes, backing-pixel, or save-under of a mapped window +may have no immediate effect. + +Multiple clients can select input on the same window; their event-masks are +disjoint. When an event is generated, it will be reported to all interested +clients. However, only one client at a time can select for SubstructureRedirect +, only one client at a time can select for ResizeRedirect, and only one client +at a time can select for ButtonPress. An attempt to violate these restrictions +results in an Access error. + +There is only one do-not-propagate-mask for a window, not one per client. + +Changing the colormap of a window (by defining a new map, not by changing the +contents of the existing map) generates a ColormapNotify event.

Otherwise, the following is +performed: + +If some other client has selected ResizeRedirect on the window and the inside +width or height of the window is being changed, a ResizeRequest event is +generated, and the current inside width and height are used instead. Note that +the override-redirect attribute of the window has no effect on ResizeRedirect +and that SubstructureRedirect on the parent has precedence over ResizeRedirect +on the window. + +The geometry of the window is changed as specified, the window is restacked +among siblings, and a ConfigureNotify event is generated if the state of the +window actually changes. If the inside width or height of the window has +actually changed, then children of the window are affected, according to their +win-gravity. Exposure processing is performed on formerly obscured windows +(including the window itself and its inferiors if regions of them were obscured +but now are not). Exposure processing is also performed on any new regions of +the window (as a result of increasing the width or height) and on any regions +where window contents are lost. + +If the inside width or height of a window is not changed but the window is +moved or its border is changed, then the contents of the window are not lost +but move with the window. Changing the inside width or height of the window +causes its contents to be moved or lost, depending on the bit-gravity of the +window. It also causes children to be reconfigured, depending on their +win-gravity. For a change of width and height of W and H, we define the [x, y] +pairs as: + +┌─────────┬───────────┐ +│Direction│Deltas │ +├─────────┼───────────┤ +│NorthWest│[0, 0] │ +├─────────┼───────────┤ +│North │[W/2, 0] │ +├─────────┼───────────┤ +│NorthEast│[W, 0] │ +├─────────┼───────────┤ +│West │[0, H/2] │ +├─────────┼───────────┤ +│Center │[W/2, H/2] │ +├─────────┼───────────┤ +│East │[W, H/2] │ +├─────────┼───────────┤ +│SouthWest│[0, H] │ +├─────────┼───────────┤ +│South │[W/2, H] │ +├─────────┼───────────┤ +│SouthEast│[W, H] │ +└─────────┴───────────┘ + +When a window with one of these bit-gravities is resized, the corresponding +pair defines the change in position of each pixel in the window. When a window +with one of these win-gravities has its parent window resized, the +corresponding pair defines the change in position of the window within the +parent. This repositioning generates a GravityNotify event. GravityNotify +events are generated after the ConfigureNotify event is generated. + +A gravity of Static indicates that the contents or origin should not move +relative to the origin of the root window. If the change in size of the window +is coupled with a change in position of [X, Y], then for bit-gravity the change +in position of each pixel is [-X, -Y] and for win-gravity the change in +position of a child when its parent is so resized is [-X, -Y]. Note that Static +gravity still only takes effect when the width or height of the window is +changed, not when the window is simply moved. + +A bit-gravity of Forget indicates that the window contents are always discarded +after a size change, even if backing-store or save-under has been requested. +The window is tiled with its background (except, if no background is defined, +the existing screen contents are not altered) and zero or more exposure events +are generated. + +The contents and borders of inferiors are not affected by their parent's +bit-gravity. A server is permitted to ignore the specified bit-gravity and use +Forget instead. + +A win-gravity of Unmap is like NorthWest, but the child is also unmapped when +the parent is resized, and an UnmapNotify event is generated.

A pixel is part of the line (and hence drawn) if the center of the +pixel is fully inside the bounding box, which is viewed as having infinitely +thin edges. If the center of the pixel is exactly on the bounding box, it is +part of the line if and only if the interior is immediately to its right (x +increasing direction). Pixels with centers on a horizontal edge are a special +case and are part of the line if and only if the interior or the boundary is +immediately below (y increasing direction) and if the interior or the boundary +is immediately to the right (x increasing direction). Note that this +description is a mathematical model describing the pixels that are drawn for a +wide line and does not imply that trigonometry is required to implement such a +model. Real or fixed point arithmetic is recommended for computing the corners +of the line endpoints for lines greater than one pixel in width. + +Thin lines (zero line-width) are nominally one pixel wide lines drawn using an +unspecified, device-dependent algorithm. There are only two constraints on this +algorithm. First, if a line is drawn unclipped from [x1,y1] to [x2,y2] and +another line is drawn unclipped from [x1+dx,y1+dy] to [x2+dx,y2+dy], then a +point [x,y] is touched by drawing the first line if and only if the point +[x+dx,y+dy] is touched by drawing the second line. Second, the effective set of +points comprising a line cannot be affected by clipping. Thus, a point is +touched in a clipped line if and only if the point lies inside the clipping +region and the point would be touched by the line when drawn unclipped. + +Note that a wide line drawn from [x1,y1] to [x2,y2] always draws the same +pixels as a wide line drawn from [x2,y2] to [x1,y1], not counting cap-style and +join-style. Implementors are encouraged to make this property true for thin +lines, but it is not required. A line-width of zero may differ from a +line-width of one in which pixels are drawn. In general, drawing a thin line +will be faster than drawing a wide line of width one, but thin lines may not +mix well aesthetically with wide lines because of the different drawing +algorithms. If it is desirable to obtain precise and uniform results across all +displays, a client should always use a line-width of one, rather than a +line-width of zero. + +The line-style defines which sections of a line are drawn: + +Solid The full path of the line is drawn. + The full path of the line is drawn, but the even dashes are filled +DoubleDash differently than the odd dashes (see fill-style), with Butt + cap-style used where even and odd dashes meet. + Only the even dashes are drawn, and cap-style applies to all +OnOffDash internal ends of the individual dashes (except NotLast is treated as + Butt). + +The cap-style defines how the endpoints of a path are drawn: + +NotLast The result is equivalent to Butt, except that for a line-width of + zero the final endpoint is not drawn. +Butt The result is square at the endpoint (perpendicular to the slope of + the line) with no projection beyond. + The result is a circular arc with its diameter equal to the +Round line-width, centered on the endpoint; it is equivalent to Butt for + line-width zero. + The result is square at the end, but the path continues beyond the +Projecting endpoint for a distance equal to half the line-width; it is + equivalent to Butt for line-width zero. + +The join-style defines how corners are drawn for wide lines: + +Miter The outer edges of the two lines extend to meet at an angle. However, if + the angle is less than 11 degrees, a Bevel join-style is used instead. +Round The result is a circular arc with a diameter equal to the line-width, + centered on the joinpoint. +Bevel The result is Butt endpoint styles, and then the triangular notch is + filled. + +For a line with coincident endpoints (x1=x2, y1=y2), when the cap-style is +applied to both endpoints, the semantics depends on the line-width and the +cap-style: + +NotLast thin This is device-dependent, but the desired effect is that + nothing is drawn. +Butt thin This is device-dependent, but the desired effect is that a + single pixel is drawn. +Round thin This is the same as Butt/thin. +Projecting thin This is the same as Butt/thin. +Butt wide Nothing is drawn. +Round wide The closed path is a circle, centered at the endpoint and with + a diameter equal to the line-width. + The closed path is a square, aligned with the coordinate axes, +Projecting wide centered at the endpoint and with sides equal to the + line-width. + +For a line with coincident endpoints (x1=x2, y1=y2), when the join-style is +applied at one or both endpoints, the effect is as if the line was removed from +the overall path. However, if the total path consists of (or is reduced to) a +single point joined with itself, the effect is the same as when the cap-style +is applied at both endpoints. + +The tile/stipple represents an infinite two-dimensional plane with the tile/ +stipple replicated in all dimensions. When that plane is superimposed on the +drawable for use in a graphics operation, the upper-left corner of some +instance of the tile/stipple is at the coordinates within the drawable +specified by the tile/stipple origin. The tile/stipple and clip origins are +interpreted relative to the origin of whatever destination drawable is +specified in a graphics request. + +The tile pixmap must have the same root and depth as the gcontext (or a Match +error results). The stipple pixmap must have depth one and must have the same +root as the gcontext (or a Match error results). For fill-style Stippled (but +not fill-style OpaqueStippled), the stipple pattern is tiled in a single plane +and acts as an additional clip mask to be ANDed with the clip-mask. Any size +pixmap can be used for tiling or stippling, although some sizes may be faster +to use than others. + +The fill-style defines the contents of the source for line, text, and fill +requests. For all text and fill requests (for example, PolyText8, PolyText16, +PolyFillRectangle, FillPoly, and PolyFillArc) as well as for line requests with +line-style Solid, (for example, PolyLine, PolySegment, PolyRectangle, PolyArc ) +and for the even dashes for line requests with line-style OnOffDash or +DoubleDash: + +Solid Foreground +Tiled Tile + A tile with the same width and height as stipple but with +OpaqueStippled background everywhere stipple has a zero and with foreground + everywhere stipple has a one +Stippled Foreground masked by stipple + +For the odd dashes for line requests with line-style DoubleDash: + +Solid Background +Tiled Same as for even dashes +OpaqueStippled Same as for even dashes +Stippled Background masked by stipple + +The dashes value allowed here is actually a simplified form of the more general +patterns that can be set with SetDashes. Specifying a value of N here is +equivalent to specifying the two element list [N, N] in SetDashes. The value +must be nonzero (or a Value error results). The meaning of dash-offset and +dashes are explained in the SetDashes request. + +The clip-mask restricts writes to the destination drawable. Only pixels where +the clip-mask has bits set to 1 are drawn. Pixels are not drawn outside the +area covered by the clip-mask or where the clip-mask has bits set to 0. The +clip-mask affects all graphics requests, but it does not clip sources. The +clip-mask origin is interpreted relative to the origin of whatever destination +drawable is specified in a graphics request. If a pixmap is specified as the +clip-mask, it must have depth 1 and have the same root as the gcontext (or a +Match error results). If clip-mask is None, then pixels are always drawn, +regardless of the clip origin. The clip-mask can also be set with the +SetClipRectangles request. + +For ClipByChildren, both source and destination windows are additionally +clipped by all viewable InputOutput children. For IncludeInferiors, neither +source nor destination window is clipped by inferiors. This will result in +including subwindow contents in the source and drawing through subwindow +boundaries of the destination. The use of IncludeInferiors with a source or +destination window of one depth with mapped inferiors of differing depth is not +illegal, but the semantics is undefined by the core protocol. + +The fill-rule defines what pixels are inside (that is, are drawn) for paths +given in FillPoly requests. EvenOdd means a point is inside if an infinite ray +with the point as origin crosses the path an odd number of times. For Winding, +a point is inside if an infinite ray with the point as origin crosses an +unequal number of clockwise and counterclockwise directed path segments. A +clockwise directed path segment is one that crosses the ray from left to right +as observed from the point. A counter-clockwise segment is one that crosses the +ray from right to left as observed from the point. The case where a directed +line segment is coincident with the ray is uninteresting because one can simply +choose a different ray that is not coincident with a segment. + +For both fill rules, a point is infinitely small and the path is an infinitely +thin line. A pixel is inside if the center point of the pixel is inside and the +center point is not on the boundary. If the center point is on the boundary, +the pixel is inside if and only if the polygon interior is immediately to its +right (x increasing direction). Pixels with centers along a horizontal edge are +a special case and are inside if and only if the polygon interior is +immediately below (y increasing direction). + +The arc-mode controls filling in the PolyFillArc request. + +The graphics-exposures flag controls GraphicsExposure event generation for +CopyArea and CopyPlane requests (and any similar requests defined by +extensions). + +The default component values are: + +┌─────────────────────┬───────────────────────────────────────────────────────┐ +│Component │Default │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│function │Copy │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│plane-mask │all ones │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│foreground │0 │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│background │1 │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│line-width │0 │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│line-style │Solid │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│cap-style │Butt │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│join-style │Miter │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│fill-style │Solid │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│fill-rule │EvenOdd │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│arc-mode │PieSlice │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│ │Pixmap of unspecified size filled with foreground pixel│ +│ │ │ +│tile │(that is, client specified pixel if any, else 0) │ +│ │ │ +│ │(subsequent changes to foreground do not affect this │ +│ │pixmap) │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│stipple │Pixmap of unspecified size filled with ones │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│tile-stipple-x-origin│0 │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│tile-stipple-y-origin│0 │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│font │ │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│subwindow-mode │ClipByChildren │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│graphics-exposures │True │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│clip-x-origin │0 │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│clip-y-origin │0 │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│clip-mask │None │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│dash-offset │0 │ +├─────────────────────┼───────────────────────────────────────────────────────┤ +│dashes │4 (that is, the list [4, 4]) │ +└─────────────────────┴───────────────────────────────────────────────────────┘ + +Storing a pixmap in a gcontext might or might not result in a copy being made. +If the pixmap is later used as the destination for a graphics request, the +change might or might not be reflected in the gcontext.

All of the elements must be nonzero (or a Value error results). The +dash-offset defines the phase of the pattern, specifying how many pixels into +dashes the pattern should actually begin in any single graphics request. +Dashing is continuous through path elements combined with a join-style but is +reset to the dash-offset between each sequence of joined lines. + +The unit of measure for dashes is the same as in the ordinary coordinate +system. Ideally, a dash length is measured along the slope of the line, but +implementations are only required to match this ideal for horizontal and +vertical lines. Failing the ideal semantics, it is suggested that the length be +measured along the major axis of the line. The major axis is defined as the x +axis for lines drawn at an angle of between -45 and +45 degrees or between 135 +and 225 degrees from the x axis. For all other lines, the major axis is the y +axis. + +For any graphics primitive, the computation of the endpoint of an individual +dash only depends on the geometry of the primitive, the start position of the +dash, the direction of the dash, and the dash length. + +For any graphics primitive, the total set of pixels used to render the +primitive (both even and odd numbered dash elements) with DoubleDash line-style +is the same as the set of pixels used to render the primitive with Solid +line-style. + +For any graphics primitive, if the primitive is drawn with OnOffDash or +DoubleDash line-style unclipped at position [x,y] and again at position +[x+dx,y+dy], then a point [x1,y1] is included in a dash in the first instance +if and only if the point [x1+dx,y1+dy] is included in the dash in the second +instance. In addition, the effective set of points comprising a dash cannot be +affected by clipping.

If +the magnitude of angle2 is greater than 360 degrees, it is truncated to 360 +degrees. The x and y coordinates of the rectangle are relative to the origin of +the drawable. For an arc specified as [x,y,w,h,a1,a2], the origin of the major +and minor axes is at [x+(w/2),y+(h/2)], and the infinitely thin path describing +the entire circle/ellipse intersects the horizontal axis at [x,y+(h/2)] and +[x+w,y+(h/2)] and intersects the vertical axis at [x+(w/2),y] and [x+(w/ +2),y+h].

If C colors, R reds, G greens, and B +blues are requested, then C pixels are returned, and the masks have R, G, and B +bits set, respectively. If contiguous is True, then each mask will have a +contiguous set of bits. No mask will have any bits in common with any other +mask or with any of the pixels. For DirectColor, each mask will lie within the +corresponding pixel subfield. By ORing together subsets of masks with pixels, +C*%2 sup R+G+B% distinct pixels can be produced; all of these are allocated +writable by the request. The initial RGB values of the allocated entries are +undefined. In the colormap, there are only C*%2 sup R% independent red entries, +C*%2 sup G% independent green entries, and C*%2 sup B% independent blue +entries. This is true even for PseudoColor. When the colormap entry for a pixel +value is changed using StoreColors or StoreNamedColor, the pixel is decomposed +according to the masks and the corresponding independent entries are updated. + +FreeColors + +cmap: COLORMAP +pixels: LISTofCARD32 +plane-mask: CARD32 +Errors: Access, Colormap, Value + +The plane-mask should not have any bits in common with any of the pixels. The +set of all pixels is produced by ORing together subsets of plane-mask with the +pixels. The request frees all of these pixels that were allocated by the client +(using AllocColor, AllocNamedColor, AllocColorCells, and AllocColorPlanes). +Note that freeing an individual pixel obtained from AllocColorPlanes may not +actually allow it to be reused until all of its related pixels are also freed. +Similarly, a read-only entry is not actually freed until it has been freed by +all clients, and if a client allocates the same read-only entry multiple times, +it must free the entry that many times before the entry is actually freed. + +All specified pixels that are allocated by the client in cmap are freed, even +if one or more pixels produce an error. A Value error is generated if a +specified pixel is not a valid index into cmap. An Access error is generated if +a specified pixel is not allocated by the client (that is, is unallocated or is +only allocated by another client) or if the colormap was created with all +entries writable (using an alloc value of All in CreateColormap).

Both +source and mask (if specified) must have depth one (or a Match error results), +but they can have any root. The mask pixmap defines the shape of the cursor. +That is, the bits set to 1 in the mask define which source pixels will be +displayed, and where the mask has bits set to 0, the corresponding bits of the +source pixmap are ignored. If no mask is given, all pixels of the source are +displayed. The mask, if present, must be the same size as the source (or a +Match error results). The x and y coordinates define the hotspot relative to +the source's origin and must be a point within the source (or a Match error +results). + +The components of the cursor may be transformed arbitrarily to meet display +limitations. + +The pixmaps can be freed immediately if no further explicit references to them +are to be made. + +Subsequent drawing in the source or mask pixmap has an undefined effect on the +cursor.

Other negative values generate a +Value error. + +If both led-mode and led are specified, then the state of that LED is changed, +if possible. If only led-mode is specified, then the state of all LEDs are +changed, if possible. At most 32 LEDs, numbered from one, are supported. No +standard interpretation of LEDs is defined. It is a Match error if an led is +specified without an led-mode. + +If both auto-repeat-mode and key are specified, then the auto-repeat mode of +that key is changed, if possible. If only auto-repeat-mode is specified, then +the global auto-repeat mode for the entire keyboard is changed, if possible, +without affecting the per-key settings. It is a Match error if a key is +specified without an auto-repeat-mode. Each key has an individual mode of +whether or not it should auto-repeat and a default setting for that mode. In +addition, there is a global mode of whether auto-repeat should be enabled or +not and a default setting for that mode. When the global mode is On, keys +should obey their individual auto-repeat modes. When the global mode is Off, no +keys should auto-repeat. An auto-repeating key generates alternating KeyPress +and KeyRelease events. When a key is used as a modifier, it is desirable for +the key not to auto-repeat, regardless of the auto-repeat setting for that key. + +A bell generator connected with the console but not directly on the keyboard is +treated as if it were part of the keyboard. + +The order in which controls are verified and altered is server-dependent.

The acceleration is a multiplier +for movement expressed as a fraction. For example, specifying 3/1 means the +pointer moves three times as fast as normal. The fraction can be rounded +arbitrarily by the server. Acceleration only takes effect if the pointer moves +more than threshold number of pixels at once and only applies to the amount +beyond the threshold. Setting a value to -1 restores the default.

Other negative values generate a Value error. If the +timeout value is zero, screen-saver is disabled (but an activated screen-saver +is not deactivated). If the timeout value is nonzero, screen-saver is enabled. +Once screen-saver is enabled, if no input from the keyboard or pointer is +generated for timeout seconds, screen-saver is activated. For each screen, if +blanking is preferred and the hardware supports video blanking, the screen will +simply go blank. Otherwise, if either exposures are allowed or the screen can +be regenerated without sending exposure events to clients, the screen is +changed in a server-dependent fashion to avoid phosphor burn. Otherwise, the +state of the screens does not change, and screen-saver is not activated. At the +next keyboard or pointer input or at the next ForceScreenSaver with mode Reset, +screen-saver is deactivated, and all screen states are restored. + +If the server-dependent screen-saver method is amenable to periodic change, +interval serves as a hint about how long the change period should be, with zero +hinting that no periodic change should be made. Examples of ways to change the +screen include scrambling the color map periodically, moving an icon image +about the screen periodically, or tiling the screen with the root window +background tile, randomly reorigined periodically. + +GetScreenSaver + +▶ +timeout, interval: CARD16 +prefer-blanking: { Yes, No} +allow-exposures: { Yes, No} + +This request returns the current screen-saver control values. + +ForceScreenSaver + +mode: { Activate, Reset} +Errors: Value + +If the mode is Activate and screen-saver is currently deactivated, then +screen-saver is activated (even if screen-saver has been disabled with a +timeout value of zero). If the mode is Reset and screen-saver is currently +enabled, then screen-saver is deactivated (if it was activated), and the +activation timer is reset to its initial state as if device input had just been +received. + +ChangeHosts + +mode: { Insert, Delete} +host: HOST +Errors: Access, Value + +This request adds or removes the specified host from the access control list. +When the access control mechanism is enabled and a client attempts to establish +a connection to the server, the host on which the client resides must be in the +access control list, or the client must have been granted permission by a +server-dependent method, or the server will refuse the connection. + +The client must reside on the same host as the server and/or have been granted +permission by a server-dependent method to execute this request (or an Access +error results). + +An initial access control list can usually be specified, typically by naming a +file that the server reads at startup and reset. + +The following address families are defined. A server is not required to support +these families and may support families not listed here. Use of an unsupported +family, an improper address format, or an improper address length within a +supported family results in a Value error. + +For the Internet family, the address must be four bytes long. The address bytes +are in standard IP order; the server performs no automatic swapping on the +address bytes. The Internet family supports IP version 4 addresses only. + +For the InternetV6 family, the address must be sixteen bytes long. The address +bytes are in standard IP order; the server performs no automatic swapping on +the address bytes. The InternetV6 family supports IP version 6 addresses only. + +For the DECnet family, the server performs no automatic swapping on the address +bytes. A Phase IV address is two bytes long: the first byte contains the least +significant eight bits of the node number, and the second byte contains the +most significant two bits of the node number in the least significant two bits +of the byte and the area in the most significant six bits of the byte. + +For the Chaos family, the address must be two bytes long. The host number is +always the first byte in the address, and the subnet number is always the +second byte. The server performs no automatic swapping on the address bytes. + +For the ServerInterpreted family, the address may be of any length up to 65535 +bytes. The address consists of two strings of ASCII characters, separated by a +byte with a value of 0. The first string represents the type of address, and +the second string contains the address value. Address types and the syntax for +their associated values will be registered via the X.Org Registry. Implementors +who wish to add implementation specific types may register a unique prefix with +the X.Org registry to prevent namespace collisions. + +Use of a host address in the ChangeHosts request is deprecated. It is only +useful when a host has a unique, constant address, a requirement that is +increasingly unmet as sites adopt dynamically assigned addresses, network +address translation gateways, IPv6 link local addresses, and various other +technologies. It also assumes all users of a host share equivalent access +rights, and as such has never been suitable for many multi-user machine +environments. Instead, more secure forms of authentication, such as those based +on shared secrets or public key encryption, are recommended. + +ListHosts + +▶ +mode: { Enabled, Disabled} +hosts: LISTofHOST + +This request returns the hosts on the access control list and whether use of +the list at connection setup is currently enabled or disabled. + +Each HOST is padded to a multiple of four bytes. + +SetAccessControl + +mode: { Enable, Disable} +Errors: Access, Value + +This request enables or disables the use of the access control list at +connection setups. + +The client must reside on the same host as the server and/or have been granted +permission by a server-dependent method to execute this request (or an Access +error results). + +SetCloseDownMode + +mode: { Destroy, RetainPermanent, RetainTemporary} +Errors: Value + +This request defines what will happen to the client's resources at connection +close. A connection starts in Destroy mode. The meaning of the close-down mode +is described in section 10. + +KillClient + +resource: CARD32 or AllTemporary +Errors: Value + +If a valid resource is specified, KillClient forces a close-down of the client +that created the resource. If the client has already terminated in either +RetainPermanent or RetainTemporary mode, all of the client's resources are +destroyed (see section 10). If AllTemporary is specified, then the resources of +all clients that have terminated in RetainTemporary are destroyed. + +NoOperation + +This request has no arguments and no results, but the request length field +allows the request to be any multiple of four bytes in length. The bytes +contained in the request are uninterpreted by the server. + +This request can be used in its minimum four byte form as padding where +necessary by client libraries that find it convenient to force requests to +begin on 64-bit boundaries. + +Chapter 10. Connection Close + +At connection close, all event selections made by the client are discarded. If +the client has the pointer actively grabbed, an UngrabPointer is performed. If +the client has the keyboard actively grabbed, an UngrabKeyboard is performed. +All passive grabs by the client are released. If the client has the server +grabbed, an UngrabServer is performed. All selections (see SetSelectionOwner +request) owned by the client are disowned. If close-down mode (see +SetCloseDownMode request) is RetainPermanent or RetainTemporary, then all +resources (including colormap entries) allocated by the client are marked as +permanent or temporary, respectively (but this does not prevent other clients +from explicitly destroying them). If the mode is Destroy, all of the client's +resources are destroyed. + +When a client's resources are destroyed, for each window in the client's +save-set, if the window is an inferior of a window created by the client, the +save-set window is reparented to the closest ancestor such that the save-set +window is not an inferior of a window created by the client. If the save-set +window is unmapped, a MapWindow request is performed on it (even if it was not +an inferior of a window created by the client). The reparenting leaves +unchanged the absolute coordinates (with respect to the root window) of the +upper-left outer corner of the save-set window. After save-set processing, all +windows created by the client are destroyed. For each nonwindow resource +created by the client, the appropriate Free request is performed. All colors +and colormap entries allocated by the client are freed. + +A server goes through a cycle of having no connections and having some +connections. At every transition to the state of having no connections as a +result of a connection closing with a Destroy close-down mode, the server +resets its state as if it had just been started. This starts by destroying all +lingering resources from clients that have terminated in RetainPermanent or +RetainTemporary mode. It additionally includes deleting all but the predefined +atom identifiers, deleting all properties on all root windows, resetting all +device maps and attributes (key click, bell volume, acceleration), resetting +the access control list, restoring the standard root tiles and cursors, +restoring the default font path, and restoring the input focus to state +PointerRoot. + +Note that closing a connection with a close-down mode of RetainPermanent or +RetainTemporary will not cause the server to reset. + +Chapter 11. Events + +Table of Contents + +Input Device events +Pointer Window events +Input Focus events +KeymapNotify +Expose +GraphicsExposure +NoExposure +VisibilityNotify +CreateNotify +DestroyNotify +UnmapNotify +MapNotify +MapRequest +ReparentNotify +ConfigureNotify +GravityNotify +ResizeRequest +ConfigureRequest +CirculateNotify +CirculateRequest +PropertyNotify +SelectionClear +SelectionRequest +SelectionNotify +ColormapNotify +MappingNotify +ClientMessage + +When a button press is processed with the pointer in some window W and no +active pointer grab is in progress, the ancestors of W are searched from the +root down, looking for a passive grab to activate.

The generation of these logical changes +may lag the physical changes if device event processing is frozen. Note that +KeyPress and KeyRelease are generated for all keys, even those mapped to +modifier bits. The source of the event is the window the pointer is in. The +window the event is reported with respect to is called the event window. The +event window is found by starting with the source window and looking up the +hierarchy for the first window on which any client has selected interest in the +event (provided no intervening window prohibits event generation by including +the event type in its do-not-propagate-mask). The actual window used for +reporting can be modified by active grabs and, in the case of keyboard events, +can be modified by the focus window. + +The root is the root window of the source window, and root-x and root-y are the +pointer coordinates relative to root's origin at the time of the event. Event +is the event window. If the event window is on the same screen as root, then +event-x and event-y are the pointer coordinates relative to the event window's +origin. Otherwise, event-x and event-y are zero. If the source window is an +inferior of the event window, then child is set to the child of the event +window that is an ancestor of (or is) the source window. Otherwise, it is set +to None. The state component gives the logical state of the buttons and +modifier keys just before the event. The detail component type varies with the +event type: + +┌──────────────────────────┬───────────────┐ +│Event │Component │ +├──────────────────────────┼───────────────┤ +│KeyPress, KeyRelease │KEYCODE │ +├──────────────────────────┼───────────────┤ +│ButtonPress, ButtonRelease│BUTTON │ +├──────────────────────────┼───────────────┤ +│MotionNotify │{ Normal Hint }│ +└──────────────────────────┴───────────────┘ + +MotionNotify events are only generated when the motion begins and ends in the +window. The granularity of motion events is not guaranteed, but a client +selecting for motion events is guaranteed to get at least one event when the +pointer moves and comes to rest. Selecting PointerMotion receives events +independent of the state of the pointer buttons. By selecting some subset of +Button[1-5]Motion instead, MotionNotify events will only be received when one +or more of the specified buttons are pressed. By selecting ButtonMotion, +MotionNotify events will be received only when at least one button is pressed. +The events are always of type MotionNotify, independent of the selection. If +PointerMotionHint is selected, the server is free to send only one MotionNotify +event (with detail Hint) to the client for the event window until either the +key or button state changes, the pointer leaves the event window, or the client +issues a QueryPointer or GetMotionEvents request. + +Pointer Window events + +EnterNotify +LeaveNotify +root, event: WINDOW +child: WINDOW or None +same-screen: BOOL +root-x, root-y, event-x, event-y: INT16 +mode: { Normal, Grab, Ungrab} +detail: { Ancestor, Virtual, Inferior, Nonlinear, NonlinearVirtual} +focus: BOOL +state: SETofKEYBUTMASK +time: TIMESTAMP + +If pointer motion or window hierarchy change causes the pointer to be in a +different window than before, EnterNotify and LeaveNotify events are generated +instead of a MotionNotify event. Only clients selecting EnterWindow on a window +receive EnterNotify events, and only clients selecting LeaveWindow receive +LeaveNotify events. The pointer position reported in the event is always the +final position, not the initial position of the pointer. The root is the root +window for this position, and root-x and root-y are the pointer coordinates +relative to root's origin at the time of the event. Event is the event window. +If the event window is on the same screen as root, then event-x and event-y are +the pointer coordinates relative to the event window's origin. Otherwise, +event-x and event-y are zero. In a LeaveNotify event, if a child of the event +window contains the initial position of the pointer, then the child component +is set to that child. Otherwise, it is None. For an EnterNotify event, if a +child of the event window contains the final pointer position, then the child +component is set to that child. Otherwise, it is None. If the event window is +the focus window or an inferior of the focus window, then focus is True. +Otherwise, focus is False. + +Normal pointer motion events have mode Normal. Pseudo-motion events when a grab +activates have mode Grab, and pseudo-motion events when a grab deactivates have +mode Ungrab. + +All EnterNotify and LeaveNotify events caused by a hierarchy change are +generated after any hierarchy event caused by that change (that is, UnmapNotify +, MapNotify, ConfigureNotify, GravityNotify, CirculateNotify), but the ordering +of EnterNotify and LeaveNotify events with respect to FocusOut, +VisibilityNotify, and Expose events is not constrained. + +Normal events are generated as follows: + +When the pointer moves from window A to window B and A is an inferior of B: + + ● LeaveNotify with detail Ancestor is generated on A. + + ● LeaveNotify with detail Virtual is generated on each window between A and B + exclusive (in that order). + + ● EnterNotify with detail Inferior is generated on B. + +When the pointer moves from window A to window B and B is an inferior of A: + + ● LeaveNotify with detail Inferior is generated on A. + + ● EnterNotify with detail Virtual is generated on each window between A and B + exclusive (in that order). + + ● EnterNotify with detail Ancestor is generated on B. + +When the pointer moves from window A to window B and window C is their least +common ancestor: + + ● LeaveNotify with detail Nonlinear is generated on A. + + ● LeaveNotify with detail NonlinearVirtual is generated on each window + between A and C exclusive (in that order). + + ● EnterNotify with detail NonlinearVirtual is generated on each window + between C and B exclusive (in that order). + + ● EnterNotify with detail Nonlinear is generated on B. + +When the pointer moves from window A to window B on different screens: + + ● LeaveNotify with detail Nonlinear is generated on A. + + ● If A is not a root window, LeaveNotify with detail NonlinearVirtual is + generated on each window above A up to and including its root (in order). + + ● If B is not a root window, EnterNotify with detail NonlinearVirtual is + generated on each window from B's root down to but not including B (in + order). + + ● EnterNotify with detail Nonlinear is generated on B. + +When a pointer grab activates (but after any initial warp into a confine-to +window and before generating any actual ButtonPress event that activates the +grab), G is the grab-window for the grab, and P is the window the pointer is +in: + + ● EnterNotify and LeaveNotify events with mode Grab are generated (as for + Normal above) as if the pointer were to suddenly warp from its current + position in P to some position in G.

The x and y coordinates are relative to the new parent's origin and +specify the position of the upper-left outer corner of the window. The width +and height specify the inside size, not including the border. If above-sibling +is None, then the window is on the bottom of the stack with respect to +siblings. Otherwise, the window is immediately on top of the specified sibling. +The override-redirect flag is from the window's attribute. + +GravityNotify + +GravityNotify +event, window: WINDOW +x, y: INT16 + +This event is reported to clients selecting SubstructureNotify on the parent +and to clients selecting StructureNotify on the window.

The owner argument is the window that +was specified in the SetSelectionOwner request. The remaining arguments are as +in the ConvertSelection request. + +The owner should convert the selection based on the specified target type and +send a SelectionNotify back to the requestor. A complete specification for +using selections is given in the X.Org standard Inter-Client Communication +Conventions Manual. + +SelectionNotify + +SelectionNotify +requestor: WINDOW +selection, target: ATOM +property: ATOM or None +time: TIMESTAMP or CurrentTime + +This event is generated by the server in response to a ConvertSelection request +when there is no owner for the selection. When there is an owner, it should be +generated by the owner using SendEvent. The owner of a selection should send +this event to a requestor either when a selection has been converted and stored +as a property or when a selection conversion could not be performed (indicated +with property None). + +ColormapNotify + +ColormapNotify +window: WINDOW +colormap: COLORMAP or None +new: BOOL +state: { Installed, Uninstalled} + +This event is reported to clients selecting ColormapChange on the window. It is +generated with value True for new when the colormap attribute of the window is +changed and is generated with value False for new when the colormap of a window +is installed or uninstalled. In either case, the state indicates whether the +colormap is currently installed. + +MappingNotify + +MappingNotify +request: { Modifier, Keyboard, Pointer} +first-keycode, count: CARD8 + +This event is sent to all clients. There is no mechanism to express disinterest +in this event. The detail indicates the kind of change that occurred: Modifiers +for a successful SetModifierMapping, Keyboard for a successful +ChangeKeyboardMapping, and Pointer for a successful SetPointerMapping. If the +detail is Keyboard, then first-keycode and count indicate the range of altered +keycodes. + +ClientMessage + +ClientMessage +window: WINDOW +type: ATOM +format: {8, 16, 32} +data: LISTofINT8 or LISTofINT16 or LISTofINT32 + +This event is only generated by clients using SendEvent. The type specifies how +the data is to be interpreted by the receiving client; the server places no +interpretation on the type or the data. The format specifies whether the data +should be viewed as a list of 8-bit, 16-bit, or 32-bit quantities, so that the +server can correctly byte-swap, as necessary. The data always consists of +either 20 8-bit values or 10 16-bit values or 5 32-bit values, although +particular message types might not make use of all of these values. + +Chapter 12. Flow Control and Concurrency + +Whenever the server is writing to a given connection, it is permissible for the +server to stop reading from that connection (but if the writing would block, it +must continue to service other connections). The server is not required to +buffer more than a single request per connection at one time. For a given +connection to the server, a client can block while reading from the connection +but should undertake to read (events and errors) when writing would block. +Failure on the part of a client to obey this rule could result in a deadlocked +connection, although deadlock is probably unlikely unless either the transport +layer has very little buffering or the client attempts to send large numbers of +requests without ever reading replies or checking for errors and events. + +Whether or not a server is implemented with internal concurrency, the overall +effect must be as if individual requests are executed to completion in some +serial order, and requests from a given connection must be executed in delivery +order (that is, the total execution order is a shuffle of the individual +streams). The execution of a request includes validating all arguments, +collecting all data for any reply, and generating and queueing all required +events. However, it does not include the actual transmission of the reply and +the events. In addition, the effect of any other cause that can generate +multiple events (for example, activation of a grab or pointer motion) must +effectively generate and queue all required events indivisibly with respect to +all other causes and requests. For a request from a given client, any events +destined for that client that are caused by executing the request must be sent +to the client before any reply or error is sent. + +Appendix A. KEYSYM Encoding + +Table of Contents + +Special KEYSYMs +Latin-1 KEYSYMs +Unicode KEYSYMs +Function KEYSYMs +Vendor KEYSYMs +Legacy KEYSYMs + +KEYSYM values are 32-bit integers that encode the symbols on the keycaps of a +keyboard.

Some have function keys left over from early +timesharing days, others were designed for a specific application, such as text +processing, web browsing, or accessing audiovisual data. The symbols on the +keycaps can differ significantly between manufacturers and national markets, +even where they denote the same software function (e.g., Ctrl in the U.S. +versus Strg in Germany) + +There are two ways of thinking about how to define KEYSYMs for such a world: + + ● The Engraving approach + + ● The Common approach + +The Engraving approach is to create a KEYSYM for every unique key engraving. +This is effectively taking the union of all key engravings on all keyboards. +For example, some keyboards label function keys across the top as F1 through +Fn, and others label them as PF1 through PFn. These would be different keys +under the Engraving approach. Likewise, Lock would differ from Shift Lock, +which is different from the up-arrow symbol that has the effect of changing +lowercase to uppercase. There are lots of other aliases such as Del, DEL, +Delete, Remove, and so forth. The Engraving approach makes it easy to decide if +a new entry should be added to the KEYSYM set: if it does not exactly match an +existing one, then a new one is created. + +The Common approach tries to capture all of the keys present on an interesting +number of keyboards, folding likely aliases into the same KEYSYM. For example, +Del, DEL, and Delete are all merged into a single KEYSYM. Vendors can augment +the KEYSYM set (using the vendor-specific encoding space) to include all of +their unique keys that were not included in the standard set. Each vendor +decides which of its keys map into the standard KEYSYMs, which presumably can +be overridden by a user. It is more difficult to implement this approach, +because judgment is required about when a sufficient set of keyboards +implements an engraving to justify making it a KEYSYM in the standard set and +about which engravings should be merged into a single KEYSYM. + +Although neither scheme is perfect or elegant, the Common approach has been +selected because it makes it easier to write a portable application. Having the +Delete functionality merged into a single KEYSYM allows an application to +implement a deletion function and expect reasonable bindings on a wide set of +workstations. Under the Common approach, application writers are still free to +look for and interpret vendor-specific KEYSYMs, but because they are in the +extended set, the application developer is more conscious that they are writing +the application in a nonportable fashion. + +The Keyboard set is a miscellaneous collection of commonly occurring keys on +keyboards. Within this set, the numeric keypad symbols are generally duplicates +of symbols found on keys on the main part of the keyboard, but they are +distinguished here because they often have a distinguishable semantics +associated with them. + +┌────────────┬────────────────────────────────────────────────┬────────┐ +│KEYSYM value│Name │Set │

+Pointers +Predefined Atoms +Connection Setup +Requests +Events + +Syntactic Conventions + +All numbers are in decimal, unless prefixed with #x, in which case they are in +hexadecimal (base 16). + +The general syntax used to describe requests, replies, errors, events, and +compound types is: + + NameofThing + encode-form + ... + encode-form + +Each encode-form describes a single component. + +For components described in the protocol as: + + name: TYPE + +the encode-form is: + + N TYPE name + +N is the number of bytes occupied in the data stream, and TYPE is the +interpretation of those bytes. For example, + + depth: CARD8 + +becomes: + + 1 CARD8 depth + +For components with a static numeric value the encode-form is: + + N value name + +The value is always interpreted as an N-byte unsigned integer. For example, the +first two bytes of a Window error are always zero (indicating an error in +general) and three (indicating the Window error in particular): + + 1 0 Error + 1 3 code + +For components described in the protocol as: + +name: { Name1,..., NameI} + +the encode-form is: + + N name + value1 Name1 + ... + valueI NameI + +The value is always interpreted as an N-byte unsigned integer. Note that the +size of N is sometimes larger than that strictly required to encode the values. +For example: + +class: { InputOutput, InputOnly, CopyFromParent } + +becomes: + +2 class + 0 CopyFromParent + 1 InputOutput + 2 InputOnly + +For components described in the protocol as: + +NAME: TYPE or Alternative1 ...or AlternativeI + +the encode-form is: + +N TYPE NAME + value1 Alternative1 + ... + valueI AlternativeI + +The alternative values are guaranteed not to conflict with the encoding of +TYPE. For example: + +destination: WINDOW or PointerWindow or InputFocus + +becomes: + +4 WINDOW destination + 0 PointerWindow + 1 InputFocus + +For components described in the protocol as: + + value-mask: BITMASK + +the encode-form is: + +N BITMASK value-mask + mask1 mask-name1 + ... + maskI mask-nameI + +The individual bits in the mask are specified and named, and N is 2 or 4. The +most-significant bit in a BITMASK is reserved for use in defining chained +(multiword) bitmasks, as extensions augment existing core requests. The precise +interpretation of this bit is not yet defined here, although a probable +mechanism is that a 1-bit indicates that another N bytes of bitmask follows, +with bits within the overall mask still interpreted from least-significant to +most-significant with an N-byte unit, with N-byte units interpreted in stream +order, and with the overall mask being byte-swapped in individual N-byte units. + +For LISTofVALUE encodings, the request is followed by a section of the form: + + VALUEs + encode-form + ... + encode-form + +listing an encode-form for each VALUE. The NAME in each encode-form keys to the +corresponding BITMASK bit. The encoding of a VALUE always occupies four bytes, +but the number of bytes specified in the encoding-form indicates how many of +the least-significant bytes are actually used; the remaining bytes are unused +and their values do not matter. + +In various cases, the number of bytes occupied by a component will be specified +by a lowercase single-letter variable name instead of a specific numeric value, +and often some other component will have its value specified as a simple +numeric expression involving these variables. Components specified with such +expressions are always interpreted as unsigned integers. The scope of such +variables is always just the enclosing request, reply, error, event, or +compound type structure. For example: + +2 3+n request length +4n LISTofPOINT points + +For unused bytes (the values of the bytes are undefined and do no matter), the +encode-form is: + + N unused + +If the number of unused bytes is variable, the encode-form typically is: + + p unused, p=pad(E) + +where E is some expression, and pad(E) is the number of bytes needed to round E +up to a multiple of four. + + pad(E) = (4 - (E mod 4)) mod 4 + +Common Types + + In this document the LISTof notation strictly means some number of +LISTofFOO repetitions of the FOO encoding; the actual length of the list is + encoded elsewhere. + +SETofFOO A set is always represented by a bitmask, with a 1-bit indicating + presence in the set. + +BITMASK: CARD32 +WINDOW: CARD32 +PIXMAP: CARD32 +CURSOR: CARD32 +FONT: CARD32

By + default, only programs on the local host and hosts specified in an initial + list read by the server can use the display. Clients on the local host can + change this access control list. Some server implementations can also + implement other authorization mechanisms in addition to or in place of this + mechanism. The action of this mechanism can be conditional based on the + authorization protocol name and data received by the server at connection + setup. + +Active grab + + A grab is active when the pointer or keyboard is actually owned by the + single grabbing client. + +Ancestors + + If W is an inferior of A, then A is an ancestor of W. + +Atom + + An atom is a unique ID corresponding to a string name. Atoms are used to + identify properties, types, and selections. + +Background + + An InputOutput window can have a background, which is defined as a pixmap. + When regions of the window have their contents lost or invalidated, the + server will automatically tile those regions with the background. + +Backing store + + When a server maintains the contents of a window, the pixels saved off + screen are known as a backing store. + +Bit gravity + + When a window is resized, the contents of the window are not necessarily + discarded. It is possible to request that the server relocate the previous + contents to some region of the window (though no guarantees are made). This + attraction of window contents for some location of a window is known as bit + gravity. + +Bit plane + + When a pixmap or window is thought of as a stack of bitmaps, each bitmap is + called a bit plane or plane. + +Bitmap + + A bitmap is a pixmap of depth one. + +Border + + An InputOutput window can have a border of equal thickness on all four + sides of the window. A pixmap defines the contents of the border, and the + server automatically maintains the contents of the border. Exposure events + are never generated for border regions. + +Button grabbing + + Buttons on the pointer may be passively grabbed by a client. When the + button is pressed, the pointer is then actively grabbed by the client. + +Byte order + + For image (pixmap/bitmap) data, the server defines the byte order, and + clients with different native byte ordering must swap bytes as necessary. + For all other parts of the protocol, the client defines the byte order, and + the server swaps bytes as necessary. + +Children + + The children of a window are its first-level subwindows. + +Client + + An application program connects to the window system server by some + interprocess communication path, such as a TCP connection or a shared + memory buffer. This program is referred to as a client of the window system + server. More precisely, the client is the communication path itself; a + program with multiple paths open to the server is viewed as multiple + clients by the protocol. Resource lifetimes are controlled by connection + lifetimes, not by program lifetimes. + +Clipping region + + In a graphics context, a bitmap or list of rectangles can be specified to + restrict output to a particular region of the window. The image defined by + the bitmap or rectangles is called a clipping region. + +Colormap + + A colormap consists of a set of entries defining color values. The colormap + associated with a window is used to display the contents of the window; + each pixel value indexes the colormap to produce RGB values that drive the + guns of a monitor. Depending on hardware limitations, one or more colormaps + may be installed at one time, so that windows associated with those maps + display with correct colors. + +Connection + + The interprocess communication path between the server and client program + is known as a connection. A client program typically (but not necessarily) + has one connection to the server over which requests and events are sent. + +Containment + + A window “contains” the pointer if the window is viewable and the hotspot + of the cursor is within a visible region of the window or a visible region + of one of its inferiors. The border of the window is included as part of + the window for containment. The pointer is “in” a window if the window + contains the pointer but no inferior contains the pointer. + +Coordinate system + + The coordinate system has the X axis horizontal and the Y axis vertical, + with the origin [0, 0] at the upper left. Coordinates are integral, in + terms of pixels, and coincide with pixel centers. Each window and pixmap + has its own coordinate system. For a window, the origin is inside the + border at the inside upper left. + +Cursor + + A cursor is the visible shape of the pointer on a screen. It consists of a + hotspot, a source bitmap, a shape bitmap, and a pair of colors. The cursor + defined for a window controls the visible appearance when the pointer is in + that window. + +Depth + + The depth of a window or pixmap is the number of bits per pixel that it + has. The depth of a graphics context is the depth of the drawables it can + be used in conjunction with for graphics output. + +Device + + Keyboards, mice, tablets, track-balls, button boxes, and so on are all + collectively known as input devices. The core protocol only deals with two + devices, “the keyboard” and “the pointer.” + +DirectColor + + DirectColor is a class of colormap in which a pixel value is decomposed + into three separate subfields for indexing. The first subfield indexes an + array to produce red intensity values. The second subfield indexes a second + array to produce blue intensity values. The third subfield indexes a third + array to produce green intensity values. The RGB values can be changed + dynamically. + +Display + + A server, together with its screens and input devices, is called a display. + +Drawable + + Both windows and pixmaps can be used as sources and destinations in + graphics operations. These windows and pixmaps are collectively known as + drawables. However, an InputOnly window cannot be used as a source or + destination in a graphics operation. + +Event + + Clients are informed of information asynchronously by means of events. + These events can be generated either asynchronously from devices or as side + effects of client requests. Events are grouped into types. The server never + sends events to a client unless the client has specificially asked to be + informed of that type of event. However, other clients can force events to + be sent to other clients. Events are typically reported relative to a + window. + +Event mask + + Events are requested relative to a window. The set of event types that a + client requests relative to a window is described by using an event mask. + +Event synchronization + + There are certain race conditions possible when demultiplexing device + events to clients (in particular deciding where pointer and keyboard events + should be sent when in the middle of window management operations). The + event synchronization mechanism allows synchronous processing of device + events. + +Event propagation + + Device-related events propagate from the source window to ancestor windows + until some client has expressed interest in handling that type of event or + until the event is discarded explicitly. + +Event source + + The window the pointer is in is the source of a device-related event. + +Exposure event + + Servers do not guarantee to preserve the contents of windows when windows + are obscured or reconfigured. Exposure events are sent to clients to inform + them when contents of regions of windows have been lost. + +Extension + + Named extensions to the core protocol can be defined to extend the system. + Extension to output requests, resources, and event types are all possible + and are expected. + +Focus window + + The focus window is another term for the input focus. + +Font + + A font is a matrix of glyphs (typically characters). The protocol does no + translation or interpretation of character sets. The client simply + indicates values used to index the glyph array. A font contains additional + metric information to determine interglyph and interline spacing. + +GC, GContext + + GC and gcontext are abbreviations for graphics context. + +Glyph + + A glyph is an image, typically of a character, in a font. + +Grab + + Keyboard keys, the keyboard, pointer buttons, the pointer, and the server + can be grabbed for exclusive use by a client. In general, these facilities + are not intended to be used by normal applications but are intended for + various input and window managers to implement various styles of user + interfaces. + +Graphics context + + Various information for graphics output is stored in a graphics context + such as foreground pixel, background pixel, line width, clipping region, + and so on. A graphics context can only be used with drawables that have the + same root and the same depth as the graphics context. + +Gravity + + See bit gravity and window gravity. + +GrayScale + + GrayScale can be viewed as a degenerate case of PseudoColor, in which the + red, green, and blue values in any given colormap entry are equal, thus + producing shades of gray. The gray values can be changed dynamically. + +Hotspot + + A cursor has an associated hotspot that defines the point in the cursor + corresponding to the coordinates reported for the pointer. + +Identifier + + An identifier is a unique value associated with a resource that clients use + to name that resource. The identifier can be used over any connection. + +Inferiors + + The inferiors of a window are all of the subwindows nested below it: the + children, the children's children, and so on. + +Input focus + + The input focus is normally a window defining the scope for processing of + keyboard input. If a generated keyboard event would normally be reported to + this window or one of its inferiors, the event is reported normally. + Otherwise, the event is reported with respect to the focus window. The + input focus also can be set such that all keyboard events are discarded and + such that the focus window is dynamically taken to be the root window of + whatever screen the pointer is on at each keyboard event. + +Input manager + + Control over keyboard input is typically provided by an input manager + client. + +InputOnly window + + An InputOnly window is a window that cannot be used for graphics requests. + InputOnly windows are invisible and can be used to control such things as + cursors, input event generation, and grabbing. InputOnly windows cannot + have InputOutput windows as inferiors. + +InputOutput window + + An InputOutput window is the normal kind of opaque window, used for both + input and output. InputOutput windows can have both InputOutput and + InputOnly windows as inferiors. + +Key grabbing + + Keys on the keyboard can be passively grabbed by a client. When the key is + pressed, the keyboard is then actively grabbed by the client. + +Keyboard grabbing + + A client can actively grab control of the keyboard, and key events will be + sent to that client rather than the client the events would normally have + been sent to. + +Keysym + + An encoding of a symbol on a keycap on a keyboard. + +Mapped + + A window is said to be mapped if a map call has been performed on it. + Unmapped windows and their inferiors are never viewable or visible. + +Modifier keys + + Shift, Control, Meta, Super, Hyper, Alt, Compose, Apple, CapsLock, + ShiftLock, and similar keys are called modifier keys. + +Monochrome + + Monochrome is a special case of StaticGray in which there are only two + colormap entries. + +Obscure + + A window is obscured if some other window obscures it. Window A obscures + window B if both are viewable InputOutput windows, A is higher in the + global stacking order, and the rectangle defined by the outside edges of A + intersects the rectangle defined by the outside edges of B. Note the + distinction between obscure and occludes. Also note that window borders are + included in the calculation and that a window can be obscured and yet still + have visible regions. + +Occlude + + A window is occluded if some other window occludes it. Window A occludes + window B if both are mapped, A is higher in the global stacking order, and + the rectangle defined by the outside edges of A intersects the rectangle + defined by the outside edges of B. Note the distinction between occludes + and obscures. Also note that window borders are included in the + calculation. + +Padding + + Some padding bytes are inserted in the data stream to maintain alignment of + the protocol requests on natural boundaries. This increases ease of + portability to some machine architectures. + +Parent window + + If C is a child of P, then P is the parent of C. + +Passive grab + + Grabbing a key or button is a passive grab. The grab activates when the key + or button is actually pressed. + +Pixel value + + A pixel is an N-bit value, where N is the number of bit planes used in a + particular window or pixmap (that is, N is the depth of the window or + pixmap). For a window, a pixel value indexes a colormap to derive an actual + color to be displayed. + +Pixmap + + A pixmap is a three-dimensional array of bits. A pixmap is normally thought + of as a two-dimensional array of pixels, where each pixel can be a value + from 0 to (2^N)-1 and where N is the depth (z axis) of the pixmap. A pixmap + can also be thought of as a stack of N bitmaps. + +Plane + + When a pixmap or window is thought of as a stack of bitmaps, each bitmap is + called a plane or bit plane. + +Plane mask + + Graphics operations can be restricted to only affect a subset of bit planes + of a destination. A plane mask is a bit mask describing which planes are to + be modified. The plane mask is stored in a graphics context. + +Pointer + + The pointer is the pointing device attached to the cursor and tracked on + the screens. + +Pointer grabbing + + A client can actively grab control of the pointer. Then button and motion + events will be sent to that client rather than the client the events would + normally have been sent to. + +Pointing device + + A pointing device is typically a mouse, tablet, or some other device with + effective dimensional motion. There is only one visible cursor defined by + the core protocol, and it tracks whatever pointing device is attached as + the pointer. + +Property + + Windows may have associated properties, which consist of a name, a type, a + data format, and some data. The protocol places no interpretation on + properties. They are intended as a general-purpose naming mechanism for + clients. For example, clients might use properties to share information + such as resize hints, program names, and icon formats with a window + manager. + +Property list + + The property list of a window is the list of properties that have been + defined for the window. + +PseudoColor + + PseudoColor is a class of colormap in which a pixel value indexes the + colormap to produce independent red, green, and blue values; that is, the + colormap is viewed as an array of triples (RGB values). The RGB values can + be changed dynamically. + +Redirecting control + + Window managers (or client programs) may want to enforce window layout + policy in various ways. When a client attempts to change the size or + position of a window, the operation may be redirected to a specified client + rather than the operation actually being performed. + +Reply + + Information requested by a client program is sent back to the client with a + reply. Both events and replies are multiplexed on the same connection. Most + requests do not generate replies, although some requests generate multiple + replies. + +Request + + A command to the server is called a request. It is a single block of data + sent over a connection. + +Resource + + Windows, pixmaps, cursors, fonts, graphics contexts, and colormaps are + known as resources. They all have unique identifiers associated with them + for naming purposes. The lifetime of a resource usually is bounded by the + lifetime of the connection over which the resource was created. + +RGB values + + Red, green, and blue (RGB) intensity values are used to define color. These + values are always represented as 16-bit unsigned numbers, with 0 being the + minimum intensity and 65535 being the maximum intensity. The server scales + the values to match the display hardware. + +Root + + The root of a pixmap, colormap, or graphics context is the same as the root + of whatever drawable was used when the pixmap, colormap, or graphics + context was created. The root of a window is the root window under which + the window was created. + +Root window + + Each screen has a root window covering it. It cannot be reconfigured or + unmapped, but it otherwise acts as a full-fledged window. A root window has + no parent. + +Save set + + The save set of a client is a list of other clients' windows that, if they + are inferiors of one of the client's windows at connection close, should + not be destroyed and that should be remapped if currently unmapped. Save + sets are typically used by window managers to avoid lost windows if the + manager terminates abnormally. + +Scanline + + A scanline is a list of pixel or bit values viewed as a horizontal row (all + values having the same y coordinate) of an image, with the values ordered + by increasing x coordinate. + +Scanline order + + An image represented in scanline order contains scanlines ordered by + increasing y coordinate. + +Screen + + A server can provide several independent screens, which typically have + physically independent monitors. This would be the expected configuration + when there is only a single keyboard and pointer shared among the screens. + +Selection + + A selection can be thought of as an indirect property with dynamic type; + that is, rather than having the property stored in the server, it is + maintained by some client (the “owner”). A selection is global in nature + and is thought of as belonging to the user (although maintained by + clients), rather than as being private to a particular window subhierarchy + or a particular set of clients. When a client asks for the contents of a + selection, it specifies a selection “target type”. This target type can be + used to control the transmitted representation of the contents. For + example, if the selection is “the last thing the user clicked on” and that + is currently an image, then the target type might specify whether the + contents of the image should be sent in XY format or Z format. The target + type can also be used to control the class of contents transmitted; for + example, asking for the “looks” (fonts, line spacing, indentation, and so + on) of a paragraph selection rather than the text of the paragraph. The + target type can also be used for other purposes. The protocol does not + constrain the semantics. + +Server + + The server provides the basic windowing mechanism. It handles connections + from clients, multiplexes graphics requests onto the screens, and + demultiplexes input back to the appropriate clients. + +Server grabbing + + The server can be grabbed by a single client for exclusive use. This + prevents processing of any requests from other client connections until the + grab is completed. This is typically only a transient state for such things + as rubber-banding, pop-up menus, or to execute requests indivisibly. + +Sibling + + Children of the same parent window are known as sibling windows. + +Stacking order + + Sibling windows may stack on top of each other. Windows above other windows + both obscure and occlude those lower windows. This is similar to paper on a + desk. The relationship between sibling windows is known as the stacking + order. + +StaticColor + + StaticColor can be viewed as a degenerate case of PseudoColor in which the + RGB values are predefined and read-only. + +StaticGray + + StaticGray can be viewed as a degenerate case of GrayScale in which the + gray values are predefined and read-only. The values are typically linear + or near-linear increasing ramps. + +Stipple + + A stipple pattern is a bitmap that is used to tile a region that will serve + as an additional clip mask for a fill operation with the foreground color. + +String Equivalence + + Two ISO Latin-1 STRING8 values are considered equal if they are the same + length and if corresponding bytes are either equal or are equivalent as + follows: decimal values 65 to 90 inclusive (characters “A” to “Z”) are + pairwise equivalent to decimal values 97 to 122 inclusive (characters “a” + to “z”), decimal values 192 to 214 inclusive (characters “A grave” to “O + diaeresis”) are pairwise equivalent to decimal values 224 to 246 inclusive + (characters “a grave” to “o diaeresis”), and decimal values 216 to 222 + inclusive (characters “O oblique” to “THORN”) are pairwise equivalent to + decimal values 246 to 254 inclusive (characters “o oblique” to “thorn”). + +Tile + + A pixmap can be replicated in two dimensions to tile a region. The pixmap + itself is also known as a tile. + +Timestamp + + A timestamp is a time value, expressed in milliseconds. It typically is the + time since the last server reset. Timestamp values wrap around (after about + 49.7 days). The server, given its current time is represented by timestamp + T, always interprets timestamps from clients by treating half of the + timestamp space as being earlier in time than T and half of the timestamp + space as being later in time than T. One timestamp value (named CurrentTime + ) is never generated by the server. This value is reserved for use in + requests to represent the current server time. + +TrueColor + + TrueColor can be viewed as a degenerate case of DirectColor in which the + subfields in the pixel value directly encode the corresponding RGB values; + that is, the colormap has predefined read-only RGB values. The values are + typically linear or near-linear increasing ramps. + +Type + + A type is an arbitrary atom used to identify the interpretation of property + data. Types are completely uninterpreted by the server and are solely for + the benefit of clients. + +Viewable + + A window is viewable if it and all of its ancestors are mapped. This does + not imply that any portion of the window is actually visible. Graphics + requests can be performed on a window when it is not viewable, but output + will not be retained unless the server is maintaining backing store. + +Visible + + A region of a window is visible if someone looking at the screen can + actually see it; that is, the window is viewable and the region is not + occluded by any other window. + +Window gravity + + When windows are resized, subwindows may be repositioned automatically + relative to some position in the window. This attraction of a subwindow to + some part of its parent is known as window gravity. + +Window manager + + Manipulation of windows on the screen and much of the user interface + (policy) is typically provided by a window manager client. + +XYFormat + + The data for a pixmap is said to be in XY format if it is organized as a + set of bitmaps representing individual bit planes, with the planes + appearing from most-significant to least-significant in bit order. + +ZFormat + + The data for a pixmap is said to be in Z format if it is organized as a set + of pixel values in scanline order. + +Index + +A + +Access control list, ChangeHosts, Glossary +Active grab, Glossary + + keyboard, GrabKeyboard + pointer, GrabPointer, ChangeActivePointerGrab + +AllocColor, AllocColor
