QKeyPress event in PyQt

I am having issues with my software. In my piano software if I keep pressing a key on the keyboard then it is making multiple repeated same tones of that particular key. But actually I need a single tone until the release of that particular key. I'm providing a part of my code that detects the keyPress event and calls the corresponding method. So what should be the changes that I've to do with my code??

def keyPressEvent(self, event):
    if type(event) == QtGui.QKeyEvent and event.key() == QtCore.Qt.Key_A : 
        self.Playnote('/home/hemanth/hemanth/Piano/C.mp3')
        self.ui.pushButton.animateClick(100)
    if type(event) == QtGui.QKeyEvent and event.key() == QtCore.Qt.Key_S:
        self.Playnote('/home/hemanth/hemanth/Piano/D.mp3')
        self.ui.pushButton_2.animateClick(100)
Solution

  • You should check event.isAutoRepeat() to determine if the event is caused by keyboard autorepeat or an actual keypress. If it is an autorepeat, ignore that press.
