+<p>The call on the first phase constructor method of the UI controller
+occurs in the <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknDocument.html" format="application/java-archive"><parmname>CAknDocument</parmname></xref>-derived

+UI controller are as follows:</p>
+<ul>
+<li><p>C++ default constructor, which cannot contain any code that
+might leave. A common implementation is:</p>
+<itemgroup>
+<codeblock id="GUID-277B178E-63D3-4201-A9EB-041E597CA455" xml:space="preserve">CMyAppAppUi::CMyAppAppUi()
+    {
+    // No implementation required
+    }</codeblock>
+<p>The class declaration for this constructor in the class header file
+needs to be public to support the construction method required.</p>
+</itemgroup>
+</li>
+<li><p>Symbian 2nd phase constructor with code that might leave.
+A common implementation is:</p>
+<itemgroup>
+<codeblock id="GUID-D6CB5AB6-012E-43ED-A25A-A903532BB650" xml:space="preserve">
