Hello -- I'm having a problem that's specific to GTK on Quartz for the Mac (GTK-OSX), in case anyone has knowledge of that port. We have a cross-platform windowing system written in lisp, which on the Linux platform is built on top of GTK, where it works fine. Now I'm trying to bring it up on GTK-OSX, and there's a basic problem. It comes up and runs, but from what I'm seeing on the screen, it appears that it's not doing clipping between sibling and cousin GTK widgets, and so a widget often gets drawn over sibling or cousin widgets that are in front of it. Is there a known difference related to this in GTK on Quartz, or should it work the same as on X? I'm not seeing anything in the GTK API that would give me control over clipping between widgets other than the GDK_CLIP_BY_CHILDREN flag, though that flag is presumably on by default and it doesn't help to enable it explicitly. Our windowing system doesn't use GTK's preferred "packing" model, where sibling widgets are arranged side-by-side without overlapping each other. Our system was designed long ago on the model where windows are placed explicitly at arbitrary positions, often with overlap between siblings. So we use the GtkFixed class for our generic windows. We also call gtk_fixed_set_has_window on each one, passing TRUE, which on X causes each GtkFixed widget to use a real X window, and I believe that it's the underlying X window system that's doing the clipping between the sibling X windows. So my guess is that GTK on Quartz is not doing something similar to achieve clipping between sibling widgets. Maybe gtk_fixed_set_has_window isn't creating a Quartz window for the GtkFixed widget, or maybe non-top-level Quartz windows don't automatically do clipping between siblings. I don't know Quartz at all, though, so I don't have a good guess about that. I didn't have much success googling for that info. Ken Cheetham cheetham@xxxxxxxxx Franz Inc.
