a dialog</title><prolog><metadata><keywords></keywords></metadata></prolog><conbody>
<p>Constructing and running a dialog is quite straightforward:</p>
<codeblock xml:space="preserve" id="GUID-E91FFC65-C45C-41F0-924F-F8ECE8F4B9AA">void CDlgappAppUi::ConstructL()
    {
    BaseConstructL();
    iAppView = new (ELeave) CDlgAppMainView;
    iAppView-&gt;ExecuteLD(R_DLGAPP_MAIN_DIALOG); // modeless
    AddToStackL(iAppView);
    }
</codeblock>
<p>Because the dialog is modeless, <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCEikDialog.html#2bb826c038d23806445872d768e7d151" format="application/java-archive"><parmname>CEikDialog::ExecuteLD()</parmname></xref> returns
immediately after being called. The dialog can (and must) be added to the
control stack with the <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Control_Environment/CCoeAppUiClass.html#%3a%3aCCoeAppUi%3a%3aAddToStackL%28CCoeControl%20%2a%2cTInt%2cTInt%29" format="application/java-archive"><parmname>CCoeAppUi::AddToStackL()</parmname></xref> method, because
modeless dialogs do not do this for themselves.</p>
<p>The application extends the dialog just as it would normally extend
a <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Control_Environment/CCoeControlClass.html" format="application/java-archive"><parmname>CCoeControl</parmname></xref>-derived view in order to achieve
the desired functionality. For more information, see <xref href="GUID-B5DE1C86-2B16-4B22-887F-7079E54A8ED6.dita">Traditional
Symbian UI application architecture</xref>.</p>
