[Qt-interest] fullscreen windows on X11 +Xinerama

[Wesley Smith]

I'm having some issues trying to get fullscreen windows to span
multiple heads on X11 with Xinerama.  I'm on ubuntu Jaunty with Qt
4.3.  From what I can tell, the window manager is restricting windows
to be the size of one monitor.  I've also tried setting the window to
be borderless with a size equivalent to the multi-head display and i'm
not able to get the window beyond one monitor without dragging it
manually.

I've managed to get a proper multihead fullscreen window in X11
directly using XSetWindowAttrbutes.override_redirect = True and adding
the CWOverrideRedirect flag to the window mask field of XCreateWindow.
 Now I'm looking for a way to do this through Qt.  Is there any way
for meet to somehow add these flags while still using QWidget's show
method to turn a widget into a window?

thanks,
wes
