PyQt: QLineEdit input mask for only Integer or only String and length restriction

Question

These are the 2 questions(both can be solved by InputMask?)

1. I want to restrict the user input to 16 characters only
2. In a field like \'Age/ID\', I would li

Answer 1

To solve the first question we only have to establish a maximum size:

self.lineedit_15.setMaxLength(16)

In contrast the second QIntValidator question only works up to a maximum equal to 2147483647 since it is the maximum integer: 2**31-1, The solution is to use regular expressions:

rx = QRegExp("\d+")
self.lineedit_15.setValidator(QRegExpValidator(rx))
