application resources. Set it as application or view specific.</li>

the toolbar observer (<codeph><xref href="GUID-4C4ADE30-EE2A-31FE-B029-D0C62632064F.dita"><apiname>MAknToolbarObserver</apiname></xref></codeph>)

<li id="GUID-FDCAC051-D66D-4061-98A7-7A0DDAE8F916">In the case of a floating

toolbar, set the toolbar visible. (The framework sets the fixed toolbar automatically

visible when activating the application/view.)</li>
