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

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

app shell to the particular controls. </p> <p> <codeph>CDrawControl</codeph> illustrates

the drawing of shapes in a window. The code draws points, lines and shapes;

this exercises a variety of drawing functions provided by the window graphics

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

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