[Interest] Qt5 qml only and qfiledialog, qfontdialog, ... crash

[Alex Malyushytskyy]

setQuitOnLastWindowClosed(true)
only sets flag which is checked when any QWidget closed
and closes application when you need the last one.

So, since I assume you do not have QWIdget instances anymore,
you need manually call exit when you need to exit:.

void	QCoreApplicationexit ( int returnCode = 0 )
