Enabling quick access to functions with a toolbar

To use the Toolbar API, follow the steps below.

Link the AVKON libraries ( avkon.lib , eikcoctl.lib ) to the project file of the application.
Define the toolbar in the application resources. Set it as application or view specific.
Provide a class that implements the toolbar observer ( MAknToolbarObserver ) interface. Set the class as the observer of the toolbar ( CAknToolbar ) created in the previous step.
If the toolbar items were not defined in the resources, add them dynamically in the application code.
In the case of a floating toolbar, set the toolbar visible. (The framework sets the fixed toolbar automatically visible when activating the application/view.)
Handle toolbar events using the observer interface methods.
