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)



 Create a horizontal scrollbar widget.


void Layout()



 Layout and move horizontal scrollbar components.


Bool_t HandleButton(Event_t *event)



 Handle a mouse button event in a horizontal scrolbar.


Bool_t HandleMotion(Event_t *event)



 Handle mouse motion event in a horizontal scrollbar.


void SetRange(Int_t range, Int_t page_size)



 Set range of horizontal scrollbar.


void SetPosition(Int_t pos)



 Set logical slider position of horizontal scrollbar.
