|
20 an application shell, and two concrete controls. </p> <p> <codeph>CGraphicExampleControl</codeph> is |

22 app shell to the particular controls. </p> <p> <codeph>CDrawControl</codeph> illustrates |
|
23 the drawing of shapes in a window. The code draws points, lines and shapes; |
|
24 this exercises a variety of drawing functions provided by the window graphics |
