I have a xmDrawingAreaWidgetClass widget which I wish to have Performer
render into. I am able to do this in both Performer 1.2 and 2.0 by
passing its window id through shared memory to the pipe's configuration
callback which attaches it to the pipe. The attachment is made with
pfInitGLXGfx in pf1.2 and with pfPWinWSWindow in pf2.0. Everything works
fine accept that I'm not getting all the expose events back on the client
side of the gui interface, for either pf version. In fact, expose events
are only generated when the window is sized larger, but not when I move it
out from under another window.

I know that I'm polling for the events correctly as they are generated
up until Performer starts to render into the window.

I added expose events to the glwidget in /usr/share/Performer/src/pguide/
libpf/C++/motif.C and successfully captured all the expose events. However,
this example uses the glxMDrawWidgetClass widget which I do not have the
luxury to use because I'm being passed the window's id and also because
I must remain Performer 1.2 compatable.

Anybody?
