+the toolbar extension</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>The toolbar extension is intended for expanding fixed and floating toolbars.
+It is dependent on the parent toolbar it is located in. </p>
+<p>You must define the toolbar extension in resource definitions. You can
+add the extension to your toolbar either in resource definitions or dynamically
+during program execution like other toolbar items.</p>
+<p>Use the <codeph>AVKON_TOOLBAR_EXTENSION</codeph> resource structure when
+defining the toolbar extension. The extension structure should be defined
+in the actual toolbar’s <codeph>TBAR_CTRL</codeph> structure when defining
+the toolbar items in the resources. If you add the extension dynamically to
+the toolbar, use the extension structure resource ID when creating it.</p>
+<p>The example below shows how to add a toolbar extension as the last item
+to the view toolbar.</p>
+<codeblock xml:space="preserve">
+void CMyAppView::AddExtensionToToolbarL()
+    {
+    CAknToolbar* toolbar = Toolbar();
+    if ( toolbar )
+        {
+        CAknToolbarExtension* toolbarExtension = 
+            CAknToolbarExtension::NewL( R_MYAPP_TOOLBAR_EXTENSION );
+        toolbar-&gt;AddItemL( toolbarExtension, EAknCtToolbarExtension, 0, 0 );
+        }
+    }
+</codeblock>
+<p> You can also give the icon bitmap and skin ID information in the resource
+structure. This way you can change the default extension icon to an application
+specific icon. You can give separate bitmap or skin ID definitions to normal,
+pressed, and dimmed states.</p>
+<p>The example below shows the definition of a toolbar extension with a custom
+icon and three extension buttons.</p>

+<p>The toolbar extension events are provided to the observer of the parent
+toolbar in the same manner as the actual toolbar events. Therefore you don't
+need to (or are able to) set an observer to the toolbar extension separately.
