Troubleshooting

These items may solve your problem. Please check those you've done by changing - [ ] to - [X]

  • Searched main docs for your problem www.PySimpleGUI.org
  • Looked for Demo Programs that are similar to your goal. It is recommend you use the Demo Browser! Demos.PySimpleGUI.org
  • If not tkinter - looked for Demo Programs for specific port
  • For non tkinter - Looked at readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
  • Run your program outside of your debugger (from a command line)
  • Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.org
  • Upgraded to the latest official release of PySimpleGUI on PyPI
  • Tried using the PySimpleGUI.py file on GitHub. Your problem may have already been fixed but not released

Detailed Description

The (grab_anywhere_using_control=) feature in the window object is causing contro+arrow keys to grab and move the window down. No matter which arrow key is pressed while holding down control, the wondow moves down an increment for every contro+arrow keypress. Turning the feature off with (grab_anywhere_using_control=False),stops the problem and the control+arrow keys resume their normal text editing navigation functions (next/prior word, next/prior paragraph).

A work-around is to turn the feature off and use the Alt+mouse click to grab and move the window (which works fine). But I assume this is a bug since normally people would want to preserve normal editing functions even if the control+mouse click is used to grab and move (duplicating with alt+mouse click). Even the demo program has this problem.

# ANY code illustrates this bug. Just run anything and try the control+arrow keys.

Research direction

Reproduce the problem with a minimal PySimpleGUI program using grab_anywhere_using_control=True and Control+Arrow keys, then locate the implementation of that window option. Compare behavior with the option disabled and verify that window dragging still works without disrupting normal Control+Arrow text navigation.
