Class Description

 Semi-Abstract base class defining a generic interface to the         
 underlying, low level, graphics system (X11, Win32, MacOS).          
 An instance of TVirtualX itself defines a batch interface to the     
 graphics system.                                                     
                                                                      


TVirtualX(const char *name, const char *title) : TNamed(name, title), TAttLine(1,1,1),TAttFill(1,1),TAttText(11,0,1,62,0.01), TAttMarker(1,1,1)
 Ctor of ABC

void GetWindowAttributes(Window_t, WindowAttributes_t &attr)
 Set WindowAttributes_t structure to defaults.

Bool_t ParseColor(Colormap_t, const char *, ColorStruct_t &color)
 Set ColorStruct_t structure to default. Let system think we could
 parse color.

Bool_t AllocColor(Colormap_t, ColorStruct_t &color)
 Set pixel value. Let system think we could alocate color.

void QueryColor(Colormap_t, ColorStruct_t &color)
 Set color components to default.

void NextEvent(Event_t &event)
 Set to default event. This method however, should never be called.

void GetPasteBuffer(Window_t, Atom_t, TString &text, Int_t &nchar, Bool_t)
 Get paste buffer. By default always empty.
