Yeah, my wording was misleading.  What I wanted to say is that hide() leads to 
a hideEvent(), not the other way round.  hide() is equivalent to 
setVisible(False) and can also be caused by WM events.  (I wonder if this is 
related to the flickering effect you reported.)

See WA_DeleteOnClose:

Thinking about it, close() will eventually not do much more than hide(), 
either, IIRC (see QWidget::close() for yourself).  I don't understand how this 
can leave a taskbar entry.  (OTOH, I just learned that "proper" OS X programs 
have an application window delegate which reports the main window to the OS, 
so maybe Windows has something similar.)

Sorry if I could not really help,
