/**
   \class Qdriver
   \brief A driver implementing the methods specified by the UCdriver base class. 
  
    This driver writes to a QPicture graphics metafile. The frame() call of this
    class invokes a modal dialog QDisplayDialog that "plays" the metafile 
    in the display window. 
        
    <p>Usage: 
    
     <p>A program that uses this driver is required to include the two
     header files QTsupport.h and Qdriver.h
     
     <p>The program must be linked to the EclipseConsoleGraphics library.
