You can use eventFilter for this.

//in the header file of YourClass

  bool eventFilter(QObject *, QEvent *);

//somewhere in the cpp file of YourClass

bool YourClass::eventFilter(QObject* watched, QEvent* event) {

  if( event->type() == QEvent::FocusIn) {
    //do something when the watched object(s) gets focus
  }

  if( event->type() == QEvent::FocusOut) {
    //do something when the watched object(s) loses focus
  }
  return QWidget::eventFilter(watched, event);
}

and after initializing the QDialogButtonBox and its buttons

button->installEventFilter(this);

to install the filter.

hope that helps

Hi,

If you don't want the possible interaction with a QPushButton, why not just disable it ?

@SGaist No the interaction is with other functionality not with the QPushButton

Can you give an example ?
