view_tk.py with Python 3.8.0

[Feinwerk]

Hi

I had to change some libraries to lower case to get it working.
line1: Tkinter --> tkinter
line2: Queue --> queue
line41: Queue.Queue() --> queue.Queue()
line50: Queue.Empty --< queue.Empty

I am no Python professional maybe there is a better solution.

best regards

Alex

Create a pull request with those changes. Your solution is correct. Python 3 changed names of some modules to lowercase.
Best regards,
Martin.

I need first learn the GitHub workflow.
