Transparently get backspace event in PyQt

Question

I want to detect when backspace is pressed in a QPlainTextEdit widget.

I have the following code:

    def keyPres         


        

Answer 1

The keyPressEvent method of QPlainTextEdit already has a certain behavior that among other things is to add text, but when you overwrite it you are eliminating it, so the solution is to call the implementation of the parent not to eliminate that behavior

from PyQt5 import QtCore, QtWidgets

class PlainTextEdit(QtWidgets.QPlainTextEdit):
    def keyPressEvent(self, event):
        if event.key() == QtCore.Qt.Key_Backspace:
            print("Backspace pressed")
        super(PlainTextEdit, self).keyPressEvent(event)

if __name__ == '__main__':
    import sys
    app = QtWidgets.QApplication(sys.argv)
    w = PlainTextEdit()
    w.show()
    sys.exit(app.exec_())
