28\ingroup gpad
29
30A specialized TButton used in a group of Buttons.
31When a button from a group of TGroupButtons is selected, all other buttons
32from the group with the same name are disabled.
33
34For examples of use of TGroupButton objects, see:
35AttFillCanvas, TAttLineCanvas, TAttTextCanvas and TAttMarkerCanvas.
36
37A TGroupButton object is a specialized TPad including possible list
38of primitives used to build selections and options menus in a canvas.
