 This class creates a main window with menubar, scrollbars and a      
 drawing area. The widgets used are the new native ROOT GUI widgets.  
                                                                      


TRootCanvas(TCanvas *c, const char *name, UInt_t width, UInt_t height) : TGMainFrame(gClient->GetRoot(), width, height), TCanvasImp(c)
 Create a basic ROOT canvas.

TRootCanvas(TCanvas *c, const char *name, Int_t x, Int_t y, UInt_t width, UInt_t height) : TGMainFrame(gClient->GetRoot(), width, height), TCanvasImp(c)
 Create a basic ROOT canvas.

void CreateCanvas(const char *name)
 Create the actual canvas.

~TRootCanvas()
 Delete ROOT basic canvas. Order is significant. Delete in reverse
 order of creation.

void Close()
 Called via TCanvasImp interface by TCanvas.

void CloseWindow()
 In case window is closed via WM we get here.

UInt_t GetCwidth() const
 Return width of canvas container.

UInt_t GetCheight() const
 Return height of canvas container.

void GetWindowGeometry(Int_t &x, Int_t &y, UInt_t &w, UInt_t &h)
 Gets the size and position of the window containing the canvas. This
 size includes the menubar and borders.

void SetStatusText(const char *txt, Int_t partidx)
 Set text in status bar.

Bool_t ProcessMessage(Long_t msg, Long_t parm1, Long_t)
 Handle menu and other command generated by the user.

Int_t InitWindow()
 Called by TCanvas ctor to get window indetifier.

void SetCanvasSize(UInt_t w, UInt_t h)
 Set size of canvas container. Unix in pixels.

void SetWindowPosition(Int_t x, Int_t y)
 Set canvas position (units in pixels).

void SetWindowSize(UInt_t w, UInt_t h)
 Set size of canvas( units in pixels).

void SetWindowTitle(const char *title)
 Change title on window.

void FitCanvas()
 Fit canvas container to current window size.

void ShowMenuBar(Bool_t show)
 Show or hide menubar.

void ShowStatusBar(Bool_t show)
 Show or hide statusbar.

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.
