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                             
                                                                      




 TGVScrollBar(const TGWindow *p, UInt_t w, UInt_t h,                           UInt_t options, ULong_t back)


 Create a vertical scrollbar.



void Layout()


 Layout and move vertical scrollbar components.



Bool_t HandleButton(Event_t *event)


 Handle mouse button event in vertical scrollbar.



Bool_t HandleMotion(Event_t *event)


 Handle mouse motion in a vertical scrollbar.



void SetRange(Int_t range, Int_t page_size)


 Set range of vertical scrollbar.



void SetPosition(Int_t pos)


 Set logical slider position of vertical scrollbar.



void SavePrimitive(ostream &out, Option_t *option /*= ""*/)


 Save an vertical scrollbar as a C++ statement(s) on output stream out.



TGDimension GetDefaultSize()




 TGVScrollBar(const TGWindow *p = 0, UInt_t w = 2, UInt_t h = 4,                UInt_t options = kVerticalFrame,                Pixel_t back = GetDefaultFrameBackground())
