Hi,
I have too problems with gtkglextmm.
1) The gtkglextmm widget is not invalidated (redrawn) if the size of the
gtkglextmm area is too small. I use this instruction (from the
gtkglextmm examples): get_window()->invalidate_rect(get_allocation(),
false);
I think you should instead use this code to accomplish that:
Gdk::Rectangle lRect = get_allocation ();
get_window ()->invalidate_rect (Gdk::Rectangle (0, 0, lRect.get_width (), lRect.get_height ()),
false);
Try using BUGLE to track down the problem. It is hard to say why that happen :-)2) I have multiple gtkglextmm widgets that share the same display lists and textures. In fact, textures are compiled in display lists so that I only call display lists to draw the scene. All work fine, but if I enable texturing and at the time I am switching to the view where the display lists were initialized, I get the following message in the console:
Couldn't alloc placeholder sz 40000 ofs 7c0000

End of memory blocks
No segmentation fault happens and the program just goes on. Note that
this problem does not occur if I disable texturing.
Any ideas ?
