/** is an abstract service for a component which offers a more complex user
    interface to users within a toolbar.

    <p>
    A generic toolbar function is represented as a button which has a state
    (enabled,disabled and selected, not selected). A toolbar controller can
    be added to a toolbar and provide information or functions within a more
    sophisticated user interface.<br/> A typical example for toolbar controller
    is the font chooser within the toolbar. It provides all available fonts in
    a dropdown box and shows the current chosen font.
    <p>
