<section><title>Description</title> <p> <filepath>BitmapsShell</filepath> provides

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>The <codeph>CBitmapControl</codeph> and <codeph>CFbsControl</codeph> classes,

derived from <codeph>CGraphicExampleControl</codeph>, define behaviour for

their particular controls. </p> <p> <codeph>CBitmapControl</codeph> illustrates

the handling and rendering of bitmaps. </p> <p> <codeph>CFbsControl</codeph> illustrates

the use of the font and bitmap server. </p> </section>

<section><title>Build</title> <p>The source code for this example application

can be found in the directory: </p> <p> <filepath>examples\Graphics\Bitmaps</filepath>  </p> <p>It

may be in the directory in which you installed Symbian platform, or it may

be in <filepath>src\common\developerlibrary\</filepath>. It includes the two

project files needed for building: <filepath>bld.inf</filepath> and the <filepath>.mmp</filepath> file. </p> <p><xref href="GUID-3100800B-B2F7-50EF-BD4C-3C345ECCB2A5.dita">The Symbian platform build
