closeEvent override not working

Hello,

I'm trying to prevent a dialog from closing with the escape button by overriding the closeEvent.
I added

protected: void closeEvent(QCloseEvent *event);
to the header file, and implemented it as:

void goverDiag::closeEvent(QCloseEvent *event)
{
event->ignore();
}
It's not working though. If I push the escape button, it still closes. I can't think of another way to prevent it from closing.

You will have to capture keypress event for Esc key. Something like this should work:-

Source code

bool goverDiag::eventFilter( QObject /* *obj*/, QEvent *event )
{
if(QEvent::KeyPress == event->type())
{
if( Qt::Key_Escape == ((QKeyEvent*)event)->key())
{
return true; //ignore the event
}
return false;
}
}

You where doing it the right way (IMHO) with overriding closeEvent. The problem is that QEvent::ignore() means that YOU ignore the event so it will probably be propagated to the parent widget. Calling QEvent::accept() will do what you want.
