+views in traditional architecture</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>If the application contains multiple views and they need to be switched,
+it can be done in various ways. One of the common ways is to delete the current
+view, create a new view, and add the new one to the control stack. Here, <parmname>CMyAppUi</parmname> has
+a custom method to change a view. Often a more generic approach should be
+favored, but for simplicity the basic idea could be as follows:</p>
+<codeblock id="GUID-CEEB1B52-944E-4C2D-A9A9-AB1D55559234" xml:space="preserve">void CMyAppUi::ChangeToView2L()
+    {
+    CCoeControl* newView = CMyAppView2::NewL(ClientRect());
+    if(iCurrentView)
+        {
+        RemoveFromStack(iCurrentView);
+        delete iCurrentView;
+        }
+    iCurrentView = newView;
+    AddToStackL(iCurrentView);
+    }
+</codeblock>
+<p>Although this architecture provides the most flexible way of manipulating
+different views, the <xref href="GUID-68B999C2-0993-4804-9624-42C3D88BE5C7.dita">view
+architecture</xref> should be considered. Among other things, it provides
+a ready framework for doing the essentials in view switching.</p>
+</conbody></concept>
