Hello,
I'm trying to write a floating window over a full sreen display
(keynote presentation). After searching the archives, the best
solution seems to be CGShieldingWindowLevel(). So, I call the
following after the presentation goes into fullscreen...
[aSmallWindow setLevel:CGShieldingWindowLevel()];
when I'm done with the floating window, I call...
[aSmallWindow orderOut:self];
On some machines, this works fine. On other machines, the window
image stays on the screen until the person moves to the next slide
(i.e. does a redraw).
Is there something I should call to force a redraw? I can't figure
out why there would be different behavior on different machines. Is
there a better way to draw above a fullscreen mode? Perhaps there is
something with the floating window being faster/slower than the main
window going into fullscreen? hmmmm.
Thanks for any thoughts,
Jaime Magiera
