<section>      <p>Use the method <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classMAknToolbarObserver.html#201783ed07a47bc4081e3f1183030ca7" format="application/java-archive"><codeph>MAknToolbarObserver::DynInitToolbarL()</codeph></xref> to set properties

of toolbar items before the toolbar is shown. </p><p><codeph>DynInitToolbarL()</codeph> is

used for the toolbar notifying the observer when the toolbar is about to be

shown. This way you can use the toolbar observer to initialize the toolbar

before showing it, for example by dimming or hiding certain controls if their

functions are not available.</p>       <p>The example below shows how to hide

a toolbar item before the toolbar is drawn.</p>       <codeblock xml:space="preserve">void CMyAppView::DynInitToolbarL( TInt aResourceId, 

                                          CAknToolbar* toolbar )

    {

    if ( toolbar )

        {

        toolbar->HideItem( KButtonId, ETrue, EFalse );

        }

    }
