I have created a virtual keyboard in my application using PySide2.

And I am using the QKeyEvent to pass the key that is being pressed using the following code:

        button = self.sender()
        widget = QApplication.focusWidget()
        
        if (button.text() == "\u232b"):
            widget.backspace()
        elif (button.text() == "Space"):
            text = " "
        elif (button.text() == "&&"):
            text = "&"
        else:
            text = button.text()
        
        
        if(button.text() != "\u232b"):
            key = button.property("_key_")
            
            if hasattr(key, "toPyObject"):
                key = key.toPyObject()
            
            if widget:
                event = QtGui.QKeyEvent(
                    QtCore.QEvent.KeyPress, key, QtCore.Qt.NoModifier, text
                )
                QtCore.QCoreApplication.postEvent(widget, event)

My question is that how can I pass the backspace key?
I have a backspace button which runs the function of .backspace() which works on LineEdits but is limited to that. Other widgets do not have this option, such as the dateEdit widget.

Any suggestions?
