    19 <section><title>Description</title> <p> <filepath>GraphicsShell</filepath> provides

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

    21 a control class, derived from <codeph>CCoeControl</codeph>, which links the

    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

    25 context such as <codeph>MoveTo()</codeph>, <codeph>DrawLineTo()</codeph>, <codeph>DrawArc()</codeph> etc. </p> <p> <codeph>CZoomControl</codeph> illustrates

    26 the use of zooming. </p> </section>
