What happens after closing and before destruction?

[Raccoon29]

Hi all,

I have two related questions to ask:
1) Is it admitted to set the flag Qt::WA_DeleteOnClose for a QWidget, beyond that for the MDI subwindow that contains it?

If the answer to the 1 is "Yes", the second question:
2) What does a QWidget do right after accepting the closeEvent and before its desctruction?
Because right now this function:

void frmarticle::closeEvent(QCloseEvent *event)
{
    if(!maybeSave())  // check for modifies apported
    {
    	event->ignore(); //modifies apported stop the closement
    	return;
    }
 
    viewport->close(Article); //nullifies pointers
    event->accept(); //accepts close event, it is supposed to destroy this widget now, is it?
}
// now quits the closeEvent and the program raise exception, before calling the destructor

void frmarticle::closeEvent(QCloseEvent *event)
{
    if(!maybeSave())  // check for modifies apported
    {
    	event->ignore(); //modifies apported stop the closement
    	return;
    }

    viewport->close(Article); //nullifies pointers
    event->accept(); //accepts close event, it is supposed to destroy this widget now, is it?
}
// now quits the closeEvent and the program raise exception, before calling the destructor

So, if I would know what it does after close event and before destructor, I could debug it; if you have any other suggestion don't be shy, I accept everything.
