gdk:list-visuals ()

The list of gdk:visual objects.

Lists the available visuals for the default screen. A visual describes a hardware image data format. See the gdk:screen-list-visuals function.

For example, a visual might support 24-bit color, or 8-bit color, and might expect pixels to be in a certain format. The gdk:list-visuals function has been deprecated since version 3.22 and should not be used in newly written code. Use the call (gdk:screen-list-visuals (gdk:screen-default)).
