Cocoa: qfiledialog will not exit cleanly
Cocoa: qfiledialog will not exit cleanly

The native filedialog will not exit if it is told to
hide. To remedy this, we just add an extra interrupt call
so to inform the event dispatcher that it needs to return
the the event loop to check if it has been told to quit
