<p>In the Symbian platform, <xref href="GUID-5F749184-C804-41FC-BA81-038783BDC967.dita">resource</xref> files

are used to define UI components such as status panes, <xref href="GUID-A4F3738C-CBFD-4151-9132-26FE05966715.dita">CBA

(Control Button Area) buttons</xref>, <xref href="GUID-5918ED8A-B26B-41A0-94A6-AB6D51BF80A1.dita">menu

bars</xref>, <xref href="GUID-DAC32BB9-C0EB-42FF-A596-C2F1A90A4BD7.dita">views</xref>,

dialogs, strings, and constants used in applications. The UI components consist

of data structures that are defined in resource files, and then are called

from the classes controlling the UI implementation. When UI component implementation

is split into these two approaches, it means that resources can be recompiled,

for example for new languages, without having to recompile the application

code (unless you change the resource identifiers).</p>

<note>

<p>For demonstration purposes, the sections on resources contain examples

with arbitrary values. In your own code, it is recommend that you use a system

of easy to remember value names.</p>
