<concept id="GUID-88917386-AD48-4C76-A1C7-46F0B1E85A18" xml:lang="en"><title>Implementing

UI text localization</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>To allow your application to support different languages:</p>

<ol>

<li id="GUID-4C53C331-EDCB-49A6-A2AE-1946E0CBA85E"><p>In the resource

file for your application, use unique symbolic IDs, also known as a logical

name, for all UI texts that need to appear on the screen.</p>

<note>

<p>The Symbian platform provides some unique symbolic IDs that you can use

in your code, which means that the UI texts used for these IDs match those

used elsewhere in the device. Do not define any values for these symbolic

IDs.</p>

</note>

</li>

<li id="GUID-F64825B7-7A7F-4F07-ADFF-21C794534B39"><p>For each language

your application supports, create a resource file as follows:</p>

<ol>

<li id="GUID-509946C5-B45A-4481-8D71-F74DF32EF18A"><p>Create a text

file with the extension <parmname>lNN</parmname>, where NN is a two digit

number that matches the Symbian OS language code for your target language.</p>

<itemgroup>

<p>The file naming suggestion reflects the Symbian platform convention, Symbian

OS uses <parmname>&lt;application_name&gt;_NN.rls</parmname>.</p>

</itemgroup>

</li>

<li id="GUID-256733D4-214F-40E9-9DF1-E60469A8E8BD"><p>Define all

the symbolic IDs using the following syntax:</p>

<codeblock id="GUID-5EBA1490-2538-4AFA-B348-8D12D0322820" xml:space="preserve">#define symbolicID "value in target language"</codeblock>

<p>Each symbolic ID must be on its own line.</p></li>

<li id="GUID-AB1ADD82-91F4-4FEF-97C3-D077E73F8A4B"><p>Repeat for

each supported language.</p></li>

</ol>

</li>

<li id="GUID-089BCEFD-8E83-4CAE-80C8-14461BC333DC"><p>Create a file

to include the compiled localization files in your resource file, as follows:</p>

<ol>

<li id="GUID-44F02DD4-1502-4BAB-B128-5FC570CB6ABC"><p>Create a text

file with the extension <parmname>loc</parmname>.</p><p>The file naming

suggestion reflects the Symbian platform naming convention, Symbian OS uses <parmname>&lt;application_name&gt;.rls</parmname>.</p>

</li>

<li id="GUID-D40E9CEB-031F-405A-B031-3B5DDB84C1B2"><p>Add <parmname>#ifdef</parmname>, <parmname>#elif</parmname>,

and <parmname>#include</parmname> statements for including the appropriate

languages in your application resource files. An example syntax is as follows:</p>

<codeblock id="GUID-702C92E6-EEE5-4C0F-8498-8C182C0F0097" xml:space="preserve">#ifndef __LOCALIZATION_LOC__

#define __LOCALIZATION_LOC__

#ifdef LANGUAGE_SC			// language code for default                                               

#include "..\data\localization.l01"

#elif LANGUAGE_01			// language code for UK

#include "..\data\localization.l01"

#endif 

#endif</codeblock>

</li>

</ol>

</li>

<li id="GUID-3B918E68-258B-4724-9C15-58BC60713E75"><p>Include your <parmname>loc</parmname> file

in your resource file.</p></li>

<li id="GUID-E15A7374-0C92-48E8-8D47-955C974BFBB6"><p>Add your supported

language codes to the <parmname>LANG</parmname> statement in your project <parmname>mmp</parmname> file.</p>

</li>

<li id="GUID-F185FF9B-A926-44E5-9FAD-AD9ABFC8C215"><p>Build your

resource files</p>

<note>

<p>Some IDEs do not fully support building resource files for different

languages, so you may need to use the command line interface of the Symbian

build chain.</p>

</note>

</li>

<li id="GUID-88D12169-4847-426C-A0AE-8107DE18183F"><p>Include the

appropriate compiled resource files in your deployment package.</p><p>For

more information on deploying, see <xref href="GUID-7369BBF7-5432-455D-BBB3-872D310358F2.dita"/>.</p>

</li>

</ol>

<p> The following localization strategies are available:</p>

<ul>

<li><p>Create an installation package for each language your application

supports and add only the appropriate compiled resource file to the package</p>

</li>

<li><p>Create an installation package that includes support for

more than one language, which means there is more than one compiled resource

file in the package. The mobile device user selects the desired language upon

installation, and only the compiled resource file is installed</p></li>

<li><p>Create an installation package that includes support for

more than one language, which means there is more than one compiled resource

file in the package.</p></li>

</ul>
