gdk-list-visuals ()

A 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)).
