>From the logo example:
/* * Configure OpenGL-capable visual. */ /* Try double-buffered visual */ glconfig = gdk_gl_config_new_by_mode (GDK_GL_MODE_RGB | GDK_GL_MODE_DEPTH | GDK_GL_MODE_DOUBLE); if (glconfig == NULL) { g_print ("*** Cannot find the double-buffered visual.\n"); g_print ("*** Trying single-buffered visual.\n"); /* Try single-buffered visual */ glconfig = gdk_gl_config_new_by_mode (GDK_GL_MODE_RGB | GDK_GL_MODE_DEPTH); if (glconfig == NULL) { g_print ("*** No appropriate OpenGL-capable visual found.\n"); exit (1); } } ...... /* Set OpenGL-capability to the widget. */ gtk_widget_set_gl_capability (drawing_area, glconfig, NULL, TRUE, GDK_GL_RGBA_TYPE); This function first tries to create a glconfig using double buffered, if fails, uses single buffer). This works on OS X 10.6 Snow Leopard.
