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)
you can use exception handling for validating this:
number = self.ui.number_lineEdit.text()
try:
number = int(number)
except Exception:
QtGui.QMessageBox.about(self, 'Error','Input can only be a number')
pass
you can also use validators to validate input strings.
