<section> <title>Fixed toolbar</title><p>The UI framework always sets the+

fixed toolbar visible when an application or view is activated. You can change+

the toolbar visibility straight from the toolbar itself, like in the case+

of a floating toolbar. However, when hiding the toolbar with the <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknToolbar.html#f48c9775e05e7a6130a7c3c0d2a91199" format="application/java-archive"><codeph>CAknToolbar::SetToolbarVisibility()</codeph></xref> method, you should+
−
note that with that method the toolbar window is completely hidden and some+
−
other control should draw to its area to keep the area updated. If this is+
−
not applicable, you can use another method: <codeph>HideItemsAndDrawOnlyBackground()</codeph>.+
−
This will hide the toolbar but draw its background in the toolbar area. </p></section>+
−
<section><p>The example below shows how to hide or show the toolbar. You can+

also use <codeph>SetToolbarVisibility()</codeph> with the fixed toolbar if+

you don't need to draw the toolbar background. </p><codeblock xml:space="preserve">void CMyAppView::ChangeToolbarVisibility( TBool aHide )+
