Syntax   GUI.Disable (widgetID : int)

Description   Disables a widget specified by widgetID.

Used in conjunction with GUI.Enable to enable and disable widgets.

Disabled widgets generally are "grayed out" to visually depict their disabled status.

Disabled widgets do not respond to keystrokes or mouse clicks.
