[Qt-interest] [Qt/Mac] Stuck with user focus

[Frank Mertens]

So, it behaves like a Chinese input widget...

Nice problem, I would still try to fiddle around with
the window flags then. If there is no combination working
only a troll knows the answer -- certainly must be bug
in Qt (qt-bugs at trolltech.com).

Another strange idea: Try to catch the mouse press event
by installing an event filter on qApp and eat it up
before it hits your on-screen window...
But probably this won't help, if the focus
acquisition is already handled by the window system.
(Inspecting QFocusEvent::reason() should tell more.)
