    10 resource values available from the Symbian platform</title><prolog><metadata><keywords></keywords></metadata></prolog><conbody>

    11 <p>The Symbian SDK provides a generated resource header file that contains

    12 symbolic IDs to resources in the Symbian platform for use in your code. The

    13 file with the symbolic IDs is the <parmname>avkon.rsg</parmname> file and

    14 it is in the <parmname>./epoc32/include</parmname> folder. The file contains

    15 commonly used resource structures for your resource file declarations.</p>

    16 <p>A common example is the <parmname>R_AVKON_SOFTKEYS_OPTIONS_EXIT</parmname> symbolic

    17 ID, which maps to the <parmname>CBA</parmname> resource that results in the

    18 softkeys <parmname>Options</parmname> and <parmname>Exit</parmname>. The <parmname>Options</parmname> softkey

    19 is bound to a command that results in the application framework opening the

    20 options menu based on the <parmname>MENU_PANE</parmname> resource. The <parmname>Exit</parmname> softkey

    21 returns the <parmname>EAknSoftkeyExit</parmname> command, which would need

    22 to be handled in the appropriate place for <xref href="GUID-4941C035-C359-4968-9BD5-31F44EE5F810.dita">command

    23 handling</xref> in your application architecture. Note that the Symbian platform

    24 enumerations are in the avkon.hrh file,

    25 which is in the <parmname>/epoc32/include</parmname> folder. In general, you

    26 can map the commands returned from the CBA options by comparing the names

    27 of the symbolic IDs to the symbolic names in the enumerated list.</p>

    28 <p>Other symbolic IDs for other purposes are also available in the <parmname>avkon.rsg</parmname> file.</p>

    29 <p>When the precompiled resources fit the needs of your application, you

    30 can use them to access already existing resource structures. </p>

    31 <p>For examples of how these symbolic IDs are used, see</p>
