## Class Description

     TRootEmbeddedCanvas

     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.

void SavePrimitive(ofstream &out, Option_t *option)

     Save an embedded canvas as a C++ statement(s) on output stream out.
