Class Description

                                                                      
 TGCanvas and TGViewPort                                              
                                                                      
 A TGCanvas is a frame containing two scrollbars (a horizontal and    
 a vertical) and a viewport. The viewport acts as the window through  
 which we look at the contents of the container frame.
TGViewPort(const TGWindow *p, UInt_t w, UInt_t h, UInt_t options, ULong_t back) : TGCompositeFrame(p, w, h, options, back) 
 Create a viewport object.
void SetContainer(TGFrame *f) 
 Add container frame to the viewport. We must make sure that the added
 container is at least a TGCompositeFrame (TGCanvas::AddFrame depends
 on it).
