// TGButton, TGTextButton, TGPictureButton, TGCheckButton TGRadioButton //
// and TGSplitButton //
// //
// This header defines all GUI button widgets. //
// //
// TGButton is a button abstract base class. It defines general button //
// behaviour. //
// //
// Selecting a text or picture button will generate the event: //
// kC_COMMAND, kCM_BUTTON, button id, user data. //
// //
// Selecting a check button will generate the event: //
// kC_COMMAND, kCM_CHECKBUTTON, button id, user data. //
// //
// Selecting a radio button will generate the event: //
// kC_COMMAND, kCM_RADIOBUTTON, button id, user data. //
// //
// If a command string has been specified (via SetCommand()) then this //
// command string will be executed via the interpreter whenever a //
// button is selected. A command string can contain the macros: //
// $MSG -- kC_COMMAND, kCM[CHECK|RADIO]BUTTON packed message //
// (use GET_MSG() and GET_SUBMSG() to unpack) //
// $PARM1 -- button id //
// $PARM2 -- user data pointer //
// Before executing these macros are expanded into the respective //
// Long_t's //
// //
