Build

The source code for this example application -can be found in the directory:

examples\Graphics\GraphicsShell

It -may be in the directory in which you installed Symbian platform, or it may -be in src\common\developerlibrary\. It includes the two -project files needed for building: bld.inf and the .mmp file.

The Symbian platform 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>\.

Usage

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.
