Class Description

                                                                      
 TRootEmbeddedCanvas                                                  
                                                                      
 This class creates a TGCanvas in which a TCanvas is created. Use     
 GetCanvas() to get a pointer to the TCanvas.                         
                                                                      

 Create an TCanvas embedded in a TGFrame. A pointer to the TCanvas can
 be obtained via the GetCanvas() member function. To embed a canvas
 derived from a TCanvas do the following:
 TRootEmbeddedCanvas *embedded = new TRootEmbeddedCanvas(0, p, w, h);
      [note name must be 0, not null string ""]
 Int_t wid = embedded->GetCanvasWindowId();
 TMyCanvas *myc = new TMyCanvas("myname", 10, 10, wid);
 embedded->AdoptCanvas(myc);
      [ the MyCanvas is adopted by the embedded canvas and will be
        destroyed by it ]

 Delete embedded ROOT canvas.

 Handle mouse button events in the canvas container.

 Handle mouse button double click events in the canvas container.

 Handle configure (i.e. resize) event.

 Handle keyboard events in the canvas container.

 Handle mouse motion event in the canvas container.

 Handle expose events.

 Handle enter/leave events. Only leave is activated at the moment.
