Set QLineEdit to accept only numbers

Question

I have a QLineEdit where the user should input only numbers.

So is there a numbers-only setting for QLineEdit?

Answer 1

If you're using QT Creator 5.6 you can do that like this:

#include 

ui->myLineEditName->setValidator( new QIntValidator);

I recomend you put that line after ui->setupUi(this);

I hope this helps.
