[Interest] Calling reject() on a QFileDialog on Macintosh

[John Weeks]

We use QFileDialog::getOpenFileName() to get the native file dialog on Macintosh. If you hit Escape, the dialog closes (as it should).

If I call QDialog::reject() or even if I use this code:

			 QFileDialog * dialog =  qobject_cast<QFileDialog *>(activeModalWidget);
 			QKeyEvent * event = new QKeyEvent(QEvent::KeyPress, Qt::Key_Escape, Qt::NoModifier, QString(),0,0);
			QApplication::postEvent(dialog, event);
			event = new QKeyEvent(QEvent::KeyRelease, Qt::Key_Escape, Qt::NoModifier, QString(),0,0);
			QApplication::postEvent(dialog, event);
the dialog closes, but with Qt 5.3 it leaves the application in some sort of modal state. This puzzles me- hitting the Escape key works fine. What's the difference?

By the way, this works as I expect with Qt 4.8.6.
