Hi Karl,
I haven't heard of this specific problem before, but then most users won't
be subclassing from GraphicsWindowX11. In principle I can't see any reason
why it wouldn't work. Without code in front of me that fails to compile I
can only provides guesses as to what is amiss - my best guess is that
either a X11 header needs to be added, or the ordering needs to be adjusted.
I can't be any more specific without seeing the problem first hand and
attempting to resolve it.
Robert.
