 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 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.
