The Graphics class is a wrapper class for a device context. It also provides functionality for drawing lines, rectangles, and ellipses; writing text; saving and restoring graphic states; setting the origin of the device context; and clipping the painting area. The constructor is private since Graphics objects are intended to be created internally by Small Windows only.

When drawing a line, it can be solid, dashed, dotted, dashed and dotted, as well as dashed and double-dotted:

  class Window; 
  enum PenStyle {Solid = PS_SOLID, Dash = PS_DASH, Dot = PS_DOT, 
                 DashDot = PS_DASHDOT, DashDotDot =PS_DASHDOTDOT};
  class Graphics { 
    private: 
      Graphics(Window* windowPtr, HDC deviceContextHandle); 

The Save method saves the current state of the Graphics object and Restore restores it:

    public: 
      int Save(); 
      void Restore(int saveId);
