Class Description

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


TRootEmbeddedCanvas(const char *name, const TGWindow *p, UInt_t w, UInt_t h, UInt_t options, ULong_t back) : TGCanvas(p, w, h, options, back)
 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 ]

~TRootEmbeddedCanvas()
 Delete embedded ROOT canvas.

Bool_t HandleContainerButton(Event_t *event)
 Handle mouse button events in the canvas container.

Bool_t HandleContainerDoubleClick(Event_t *event)
 Handle mouse button double click events in the canvas container.

Bool_t HandleContainerConfigure(Event_t *)
 Handle configure (i.e. resize) event.

Bool_t HandleContainerKey(Event_t *event)
 Handle keyboard events in the canvas container.

Bool_t HandleContainerMotion(Event_t *event)
 Handle mouse motion event in the canvas container.

Bool_t HandleContainerExpose(Event_t *event)
 Handle expose events.

Bool_t HandleContainerCrossing(Event_t *event)
 Handle enter/leave events. Only leave is activated at the moment.
