be adding a picture to illustrate this point in future releases of the CDL.</draft-comment></p>

<p>The displays and keys for the mobile device are shared between all running

applications. The Symbian platform controls and coordinates access to them.

When you meet the <xref href="GUID-BDDDF68F-F7C3-43AF-8B6C-C77C701FD2A9.dita">application

framework architecture</xref> requirements, the application framework manages

connections to the underlying architecture and also controls some of the elements

on the display. While the details of what is controlled by default by the

Symbian platform and what is controlled by your application are covered in

the relevant sections of this UI section, the following cases illustrate some

divisions about what is managed where: </p>

<ul>

<li><p>in the status pane: </p>

<itemgroup>

<p>The drawing of the status pane is managed by the Symbian platform.</p>

<p>The <i>battery pane</i>, <i>universal indicator pane</i>and <i>signal

pane</i> are managed by the Symbian platform.</p>

<p>The <i>title pane</i>, <i>context pane,</i> and <i>navi pane</i> are

managed by your application, although a default behavior is provided by the

application framework.</p>

</itemgroup>

</li>

<li><p>in the control pane:</p>

<itemgroup>

<p>The drawing of the control pane is managed by the Symbian platform.</p>

<p>The labels associated with the two softkeys are provided by application

resources.</p>

<p>The event loop that collects the commands that result from selections

and the passing of these commands on to your application are handled by the

application framework.</p>

<p>The <xref href="GUID-4941C035-C359-4968-9BD5-31F44EE5F810.dita">handling

of the commands</xref> received from the application framework need to be

handled in your application.</p>

<p>For more details, see <xref href="GUID-A4F3738C-CBFD-4151-9132-26FE05966715.dita">CBA buttons</xref> and <xref href="GUID-5918ED8A-B26B-41A0-94A6-AB6D51BF80A1.dita">Menu bars</xref>.</p>
