The UM 1.1 package gets registered by QtApplication in Uranium. It should be available if you're running this through a Uranium application.

"ReferenceError: screenScaleFactor is not defined"

Thank s!

import UM 1.1 as UM //This allows you to use all of Uranium's built-in QML items.
import QtQuick 2.2 //This allows you to use QtQuick's built-in QML items.
import QtQuick.Controls 1.1

UM.Dialog //Creates a modal window that pops up above the interface.
{
id: base

width: 150 * screenScaleFactor
height: 50 * screenScaleFactor
minimumWidth: 150 * screenScaleFactor
minimumHeight: 50 * screenScaleFactor

Label //Creates a bit of text.
{
    //This aligns the text to the top-left corner of the dialogue window.
    anchors.top: base.top //Reference the dialogue window by its ID: "base".
    anchors.topMargin: 10 * screenScaleFactor
    anchors.left: base.left
    anchors.leftMargin: 10 * screenScaleFactor

    text: "Hello!"
}

}
