But you CAN'T release your textures and other GL resource in the unrealize method, because the gdk window will be already unmapped then, and gl_begin (either as glwindow->gl_begin(get_gl_context()) in C++ or gdk_gl_drawable_gl_begin (gldrawable, glcontext in plain C) will fail :-/ O. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
