Parameters: depth  A bit depth. visual_type  A visual type. Returns: Best visual with both depth and visual_type , or 0 if none. Glib::RefPtr<Visual> Gdk::Visual::get_best ( VisualType    visual_type )  [static]   Get the best visual of the given visual_type for the default GDK screen. Visuals with higher color depths are considered better. The return value should not be freed. 0 may be returned if no visual has type visual_type . Parameters: visual_type  A visual type. Returns: Best visual of the given type. Glib::RefPtr<Visual> Gdk::Visual::get_best ( int    depth )  [static]   Get the best visual with depth depth for the default GDK screen. Color visuals and visuals with mutable colormaps are preferred over grayscale or fixed-colormap visuals. The return value should not be freed. 0 may be returned if no visual supports depth . Parameters: depth  A bit depth. Returns: Best visual for the given depth. Glib::RefPtr<Visual> Gdk::Visual::get_best (   )  [static]   Get the visual with the most available colors for the default GDK screen. The return value should not be freed. Returns: Best visual. int Gdk::Visual::get_best_depth (   )  [static]   Get the best available depth for the default GDK screen. "Best" means "largest," i.e. 32 preferred over 24 preferred over 8 bits per pixel. Returns: Best available depth. VisualType Gdk::Visual::get_best_type (   )  [static]   Return the best available visual type for the default GDK screen. Returns: Best visual type. Glib::RefPtr<const Screen> Gdk::Visual::get_screen (   )  const   Gets the screen to which this visual belongs. Returns: The screen to which this visual belongs. Since: 2.2. Glib::RefPtr<Screen> Gdk::Visual::get_screen (   )    Gets the screen to which this visual belongs. Returns: The screen to which this visual belongs. Since: 2.2. Glib::RefPtr<Visual> Gdk::Visual::get_system (   )  [static]   Get the system'sdefault visual for the default GDK screen. This is the visual for the root window of the display. The return value should not be freed. Returns: System visual. const GdkVisual* Gdk::Visual::gobj (   )  const [inline]   Reimplemented from Glib::ObjectBase.
