gdk:visual-best-with-depth (depth)

depth -- an integer for the bit depth

The best gdk:visual object for the given depth.

Get the best visual with depth for the default GDK screen. Color visuals and visuals with mutable colormaps are preferred over grayscale or fixed-colormap visuals. Nil may be returned if no visual supports depth. The gdk:visual-best-with-depth function has been deprecated since version 3.22 and should not be used in newly written code. Visual selection should be done using the gdk:screen-system-visual and gdk:screen-rgba-visual functions.
