<p>In the Symbian platform, resource files are used to define UI components

</codeblock>

<p>This is the required <parmname>RESOURCE</parmname> definition that defines

the resource used for constructing the menu bar and the Control Button Area

(CBA) buttons used in the application. The menu bar is constructed later in

this resource file. The CBA buttons declaration uses a precompiled symbolic

ID from the <parmname>avkon.rsg</parmname> file, which in turns points to

a compiled resource that provides an <parmname>Options</parmname> text above

the left softkey and an <parmname>Exit</parmname> text above the right softkey.

The application framework handles the event generated by selection of the <parmname>Options</parmname> softkey

and opens the <parmname>MENU_PANE</parmname> resource. Selection of the <parmname>Exit</parmname> softkey

generates a <parmname>EAknSoftkeyExit</parmname> event that needs to be handled

by your code. For more information on event handling, see <xref href="GUID-A9330FEF-C559-4E2B-B064-0151FDADEA8C.dita">Event

handling</xref>.</p>
