Since gtk-2.20 a OpenGL-redraw sometimes clears all parent-widgets; with gtkglarea and with gtkglext and also direct into a gtk_drawing_area_new, on Linux and Windows. See Bugzilla-bugs 626751 and 645208. This problem also exists with gtk3. So we have tried to make a new opengl-binding, with a own toplevel-window for OpenGL and direct with glx. The project is Gtk-Toolbox-2.00 (GPL); see http://www.gcad3d.org/gui_gtk/devdoc/index.htm This solves the problem of clearing all parent widgets. But the following problem exists: The OpenGL-window lies exactly over an paned-window, but the OpenGL-window does not resize before idle starts. There seems to be no way to update the resize before the idle-loop starts.
In the configure-event-handler we do: gtk_widget_get_allocation (works fine) gtk_window_resize (resizes, but long after next idle ..) return FALSE; In the next following idle (gdk_threads_add_idle) we do the opengl-reconfig and redraw; but most times the gtk-window did not resize. Is there a method to wait until resize is finished ? The files are: http://www.gcad3d.org/gui_gtk/gtk_opengl_v2.c http://www.gcad3d.org/gui_gtk/tst_gui_gl2.c This means, Opengl works well in the new window, but we could not yet solve the (pure Gtk-problem) of resizing the toplevel-window claenly. Please help if you have ideas .. regards Franz Reiter _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
