QDialog and closeEvent

Hi dudes!

Is there anyway to execute some code after the user press ESC key? I override closeEvent but it does not work (but it works if I press X window button)

I read on docs if ESC key is pressed, closeEvent can not be ignored, but I just want to execute some code.


Thanks a lot.

override reject()

if you close a dialog with ESC, X window button or alt+f4 goes to reject()

Thanks.

By the way, should I do something like this:

Code:

---

void CDialogLevelProperties::reject() {
	// some code before canceling this dialog
        // bla bla bla
	QDialog::reject();
}

ya ... this should work..

What I did was override the keyPressEvent:

Code:

---

void myClass::keyPressEvent(QKeyEvent* event) {
    if (event->key() != Qt::Key_Escape) {
        QDialog::keyPressEvent(event);
    }
    else {
        close();
    }
}

Then this fires the closeEvent() which you can then work with there. But perhaps the above solution is easier.

Actually that was my former solution. That code does not work when user press X button. javimoya solution is better. Anyway, thanks.

you have to accept the event and this will work

Code:

---

void myClass::keyPressEvent(QKeyEvent* event)
{
    if (event->key() != Qt::Key_Escape)
   {
        QDialog::keyPressEvent(event);
    }
    else 
   {
       event->accept();//Bye Bye event
        close();
    }
}
