I am making a piano application in Python 2.7 using Pyqt4 and I want my keys to change color when I press a key (this is working with keyPressEvent in my app), then I want my key to change to the original color. I think I need a "KeyUp" event for that.
Does such an event exist in Pyqt4?
The correct term is "key release", not "key up". In pyqt4 you would have to use keyReleaseEvent.
