Class Description

                                                                      
 TGScrollBar and TGScrollBarElement                                   
                                                                      
 The classes in this file implement scrollbars. Scrollbars can be     
 either placed horizontal or vertical. A scrollbar contains three     
 TGScrollBarElements: The "head", "tail" and "slider". The head and   
 tail are fixed at either end and have the typical arrows in them.    
                                                                      
 The TGHScrollBar will generate the following event messages:         
 kC_HSCROLL, kSB_SLIDERPOS, position, 0                               
 kC_HSCROLL, kSB_SLIDERTRACK, position, 0                             
                                                                      
 The TGVScrollBar will generate the following event messages:         
 kC_VSCROLL, kSB_SLIDERPOS, position, 0                               
 kC_VSCROLL, kSB_SLIDERTRACK, position, 0

TGHScrollBar(const TGWindow *p, UInt_t w, UInt_t h, UInt_t options, ULong_t back) : TGScrollBar(p, w, h, options, back)

Bool_t HandleButton(Event_t *event)

 Handle a mouse button event in a horizontal scrolbar.

Bool_t HandleMotion(Event_t *event)

void SetRange(Int_t range, Int_t page_size)
