Hi all,
I'm sure there's something I'm doing wrong here, but I've been beating
my head against the clutter source and API docs for so long, I can't
figure out what it is. I'm working on an app that has its own X event
handling code, and I want to be able to use clutter in the app, so I
won't be using clutter_main(). However, when I try to use
clutter_x11_handle_event() instead, nothing happens. I get no window
or anything. If I call XSync() before I start my event loop, I get a
window that comes up, but it has garbage painted on its background.
In this case, the window appears to get events (and the clutter event
filter runs), but I get nothing painted to the window.
I can't seem to find anything special that the clutter x11 backend
event init code or clutter_main() itself does that I'm missing, but
perhaps I just can't see it.
Small test case exhibiting the problem is attached. Uncommenting the
#define near the top doesn't help (or hurt). Any ideas?
Thanks,
Brian
