Class Description

                                                                      
 TGCanvas and TGViewPort and TGContainer                              
                                                                      
 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.                
                                                                      
 A TGContainer frame manages a content area. It can display and       
 control a hierarchy of multi-column items, and provides the ability  
 to add new items at any time. By default it doesn't map subwindows   
 which are items of the container. In this case subwindow must        
 provide DrawCopy method, see for example TGLVEntry class.            
 It is also possible to use option which allow to map subwindows.     
 This option has much slower drawing speed in case of more than 1000  
 items placed in container. To activate this option the fMapSubwindows
 data member must be set to kTRUE (for example TTVLVContainer class)  
                                                                      
   The TGContainer class can handle the keys:                         
                                                                      
    o  F7, Ctnrl-F - activate search dialog                           
    o  F3, Ctnrl-G - continue search                                  
    o  End - go to the last item in container                         
    o  Home - go to the first item in container                       
    o  PageUp,PageDown,arrow keys - navigate inside container         
    o  Return/Enter - equivalent to double click of the mouse button  
    o  Contrl-A - select/activate all items.                          
    o  Space - invert selection.                                      
                                                                      

 Create a canvas container. This is the (large) frame that contains
 all the list items. It will be shown through a TGViewPort (which is
 created by the TGCanvas).
