and two concrete controls.
CGraphicExampleControl is a control class, derived from CCoeControl, which
links the app shell to the particular controls.
CDrawControl 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 MoveTo(), DrawLineTo(), DrawArc() etc.
CZoomControl illustrates the use of zooming.

The source code for this example application can be found in the directory:
examples\Graphics\GraphicsShell
This source code may be in the directory in which you installed
the Symbian platform, or it may be in the src\common\developerlibrary\ directory. The directory includes the two project files needed for
building the example: bld.inf and the .mmp file.
The Symbian build process describes
how to build this application. For the emulator, an application called GraphicsShell.exe is created in epoc32\release\winscw\<udeb
or urel>\.
Launch the emulator:
\epoc32\release\winscw\<udeb or urel>\EPOC.EXE.
Click on GRAPHICSSHELL to run the application. If using the TechView emulator, this will be in the Extras menu.
The controls are listed on the menu List of Programs. Press the appropriate menu item to select a specific control.
Step through each phase of the example by pressing the space bar or by tapping on the window drawn by that example.
