<p>The application framework contains a set of libraries and components

provided by the Symbian platform to make common functions available to applications.

Examples of the available functionality include: </p>

<ul>

<li><p><xref href="GUID-E402616A-7ED8-45AC-B836-99C3A3760B33.dita">keyboard</xref> and <xref href="GUID-4D2AA522-82AB-4D1E-9F1E-5C6A35DEF195.dita">pointer</xref> support</p>

</li>

</ul>

<p>All GUI-based applications use the application framework architecture,

which means you need to derive the application classes from base classes provided

by AVKON. For more information on the classes involved in the application

framework, see <xref href="GUID-BDDDF68F-F7C3-43AF-8B6C-C77C701FD2A9.dita">Framework

requirements for GUI applications</xref>.

For more information on the UI, see <xref href="GUID-0F593BE1-1220-4403-B04E-B8E8A9A49701.dita">UI concepts</xref>.</p>

<p>In addition, the following concepts are relevant in the context of the

application framework:</p>
