<p>To use the Toolbar API, follow the steps below.</p>

<ol>

<li id="GUID-EE77C9E2-8E00-4267-81D7-348CEA8196D5">Link the <codeph>AVKON</codeph> libraries

(<codeph>avkon.lib</codeph>, <codeph>eikcoctl.lib</codeph>) to the project

file of the application.</li>

<li id="GUID-ACA972C5-9E34-4220-9161-AFC18AD3194F">Define the toolbar in the

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

<li id="GUID-5B1DAC49-E8B3-4602-A1DF-B9071FAD8587">Provide a class that implements

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

interface. Set the class as the observer of the toolbar (<codeph><xref href="GUID-9E7F4397-3DE4-36A3-A55B-56D9E39BEFF2.dita"><apiname>CAknToolbar</apiname></xref></codeph>)

created in the previous step.</li>

<li id="GUID-37161421-986B-4DBA-8E81-57CF8AA3CBBC">If the toolbar items were

not defined in the resources, add them dynamically in the application code.</li>

<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>

<li id="GUID-32345118-A446-458E-A91D-2AEEE33E13C3">Handle toolbar events using

the observer interface methods.</li>
