Good morning,
I am trying to make a PyQt5 window (OS=MS Windows 10) that will stay on top of \
absolutely everything on my screen (like an overlay). For this, I am using:
self.setWindowFlags(QtCore.Qt.FramelessWindowHint | \
QtCore.Qt.WindowStaysOnTopHint | QtCore.Qt.WindowTransparentForInput)
So far it works perfectly with any regular window (Word, Excel, browsers, etc.). \
However, the behavior changes when the app I am trying to be on top of is a DirectX \
game.
* If I run the Python script before the game, it will show on top of it, and work \
fine. However, if I Alt-Tab out of the game and come back to it, the overlay will not \
show anymore on top the game (It will still show on top of all other windows, just \
not on top of the game).
* If I start the game before the Python script, same thing: It will show on top \
of everything, but not on top of the DirectX game.
* When I run the Python script, then the game, then Alt-Tab out of the game and \
Alt-Tab in, so it stops showing in-game, I can make it reappear if I exit and re-run \
the game from scratch (without stopping the Python script).
A good example of an script where this behavior can be seen is: \
https://github.com/georgegach/crosshair/blob/master/cross.py
Is there any option to make this PyQt5 window stay on top of absolutely everything, \
until stopped?
Thank you,
Alberto Paris
