QT Designer : Accept only numbers for IP Address

[Gokulnathvc]

Hi Qtfolks,

I am developing a QT GUI which accepts the IP Address, MAC address and Port number and validates them. The designer is as follows.

But I want the Line edit for IP address and MAC Address should be as follows.

Note : Newbie for the QT, please excuse if question doesn't make sense.

QRegExp rx("\\d+");
      QLineEdit *myEdit = new QLineEdit();
      myEdit ->setValidator(validator);
      this->setCentralWidget(myEdit );

QRegExp rx("\\d+");
      QLineEdit *myEdit = new QLineEdit();
      myEdit ->setValidator(validator);
      this->setCentralWidget(myEdit );
