Class Description

 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                                                             
                                                                      


TGButton(const TGWindow *p, Int_t id, GContext_t norm, UInt_t options) : TGFrame(p, 1, 1, options)
 Create button base class part.

~TGButton()
 Delete button.

void SetState(EButtonState state)
 Set button state.

Bool_t HandleButton(Event_t *event)
 Handle mouse button event.

Bool_t HandleCrossing(Event_t *event)
 Handle mouse crossing event.

void SetToolTipText(const char *text, Long_t delayms)
 Set tool tip text associated with this button. The delay is in
 milliseconds (minimum 250). To remove tool tip call method with
 text = 0.
