Re: [GtkGLExt] Window size issue

[Shawn Bakhtiar <shashaness hotmail com>]

I know someone brought this up before. I don't recall if there was a resolution to it or not.

I have successfully patched and compiled the latest from the GtkGLExt git repo and running on OS X Snow Leopard (10.6), although I am use the 10.5 building to the 368 architecture.

However, any application (including the examples), that uses the library, takes over the entire window, overlapping all other widgets.

Any ideas how I should trace this down?


The code is straight out of the example (which does the same thing), gtk_gl_init() has already been called in main, and the container is main_hbox, which then has other widgets added to it later in the code.

     glconfig = gdk_gl_config_new_by_mode (GDK_GL_MODE_RGB    |
                                           GDK_GL_MODE_DEPTH  |
                                           GDK_GL_MODE_DOUBLE);
   
     if(glconfig != NULL){

         GtkWidget * drawing_area = gtk_drawing_area_new ();
         gtk_widget_set_size_request (drawing_area, 200, 200);
         
         /* Set OpenGL-capability to the widget. */
         gtk_widget_set_gl_capability (drawing_area,
                                       glconfig,
                                       NULL,
                                       TRUE,
                                       GDK_GL_RGBA_TYPE);
         
         gtk_widget_add_events (drawing_area,
                                GDK_BUTTON1_MOTION_MASK    |
                                GDK_BUTTON2_MOTION_MASK    |
                                GDK_BUTTON_PRESS_MASK      |
                                GDK_VISIBILITY_NOTIFY_MASK);
         
         g_signal_connect_after (G_OBJECT (drawing_area), "realize",
                                 G_CALLBACK (realize), NULL);
         g_signal_connect (G_OBJECT (drawing_area), "configure_event",
                           G_CALLBACK (configure_event), NULL);
         g_signal_connect (G_OBJECT (drawing_area), "expose_event",
                           G_CALLBACK (expose_event), NULL);
         
         g_signal_connect (G_OBJECT (drawing_area), "button_press_event",
                           G_CALLBACK (button_press_event), NULL);
         g_signal_connect (G_OBJECT (drawing_area), "motion_notify_event",
                           G_CALLBACK (motion_notify_event), NULL);
         
         g_signal_connect (G_OBJECT (drawing_area), "map_event",
                           G_CALLBACK (map_event), NULL);
         g_signal_connect (G_OBJECT (drawing_area), "unmap_event",
                           G_CALLBACK (unmap_event), NULL);

                                   G_CALLBACK (key_press_event), drawing_area);
         
         gtk_box_pack_start (GTK_BOX (main_hbox), drawing_area, TRUE, TRUE, 0);
         
         gtk_widget_show (drawing_area);
