I have a QLineEdit and i want to restrict QLineEdit to accept only integers. It should work like inputmask. But I dont want to use inputmask, because if user clicks on QLineEdit cursor will be at the position where mouse was clicked. and user need to navigate to 0 position and type what eve he wants.

Is there any alternate for this.

you can use QValidator it works like:

#To allow only int
self.onlyInt = QIntValidator()
self.LineEdit.setValidator(self.onlyInt)
