Description

GraphicsShell provides +an application shell, 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.

Build

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>\.

+
Usage
    +
  1. Launch the emulator:

    \epoc32\release\winscw\<udeb +or urel>\EPOC.EXE.

  2. +
  3. Click on GRAPHICSSHELL to +run the application. If using the TechView emulator, this will be in +the Extras menu.

  4. +
  5. The controls are listed +on the menu List of Programs. +Press the appropriate menu item to select a specific control.

  6. +
  7. Step through each phase +of the example by pressing the space bar or by tapping on the window drawn +by that example.
