<concept id="GUID-B238952B-1691-49F4-B8B9-9F755011A7DD" xml:lang="en"><title>View

resource statements in the view architecture</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>If defined, the Symbian platform uses the <parmname>VIEW</parmname> <xref href="GUID-5F749184-C804-41FC-BA81-038783BDC967.dita">resources</xref> statements

to define separate <xref href="GUID-E849C798-07A0-47B3-BDBF-203325062FBD.dita">menu

bars</xref> and <xref href="GUID-A4F3738C-CBFD-4151-9132-26FE05966715.dita">CBAs</xref> for

different views in your application. For more information on views, see <xref href="GUID-DAC32BB9-C0EB-42FF-A596-C2F1A90A4BD7.dita">Views</xref>.</p>

<p>To define specific GUI component resources for a view:</p>

<ol>

<li id="GUID-33696BB5-19CF-4A04-90DA-DB4063308E6B"><p>Determine

the view requirements of your application.</p></li>

<li id="GUID-52943370-2366-4794-8731-E7D5AC3219FE"><p>Create a <parmname>AVKON_VIEW</parmname> resource

in your resource file. The <parmname>AVKON_VIEW</parmname> structure is defined

in the <parmname>avkon.rh</parmname> file. The syntax is as follows:</p>

<codeblock id="GUID-39D69E48-33FD-4B24-8969-AC6CA113ABF5" xml:space="preserve">RESOURCE AVKON_VIEW r_myapp_view1

{

menubar = r_myapp_menubar1;

cba = R_AVKON_SOFTKEYS_OPTIONS_BACK;

}</codeblock>

<p>where:</p>

<ul>

<li><p><parmname>r_myapp_view1</parmname> is a unique name for the

resource declaration.</p></li>

<li><p><parmname>menubar</parmname> defines the <xref href="GUID-5918ED8A-B26B-41A0-94A6-AB6D51BF80A1.dita">menubar</xref> resource.</p>

</li>

<li><p><parmname>cba</parmname> defines the <xref href="GUID-A4F3738C-CBFD-4151-9132-26FE05966715.dita">control

pane</xref> resource.</p></li>

</ul>

<p>All values refer to other resources defined either in the resource file

or to <xref href="GUID-CBB00F6A-CBA7-4872-B0A1-A86A863725F5.dita">precompiled values

available from the Symbian platform</xref>. Note that if an element is not

declared, then the default value declared in the structure is used. By default,

all elements are not used.</p></li>

<li id="GUID-28EA7785-EE88-4901-B525-DC864506FBC6"><p>Call the view

resource in the UI implementation.</p></li>

</ol>

<note>

<p>You can call <parmname>BaseConstructL()</parmname> without any parameters,

in which case the default application menu and CBA are used for the view. </p>
