//  A TGroupButton object is a specialized TButton used in a group of Buttons.
//  When a button from a group of TGroupButtons is selected, all other buttons
//  from the group with the same name are disabled.
//
//  For examples of use of TGroupButton objects, see:
//    TAttFillCanvas, TAttLineCanvas, TAttTextCanvas and TAttMarkerCanvas.
//  A TGroupButton object is a specialized TPad including possible list
//  of primitives used to build selections and options menus in a canvas.
