Package com.sun.lwuit Description

<P>
<p>
            Main widget package containing the component/container "composite" similar
            both in terminology and design to Swing/AWT. Unlike Swing/AWT a full windowing
            system is not applicable in this case and forms are placed using a Display abstraction
            more in line with the MIDP API.
        </p>
        <p>
            Components are placed in a container with layout managers that are used to detemine
            component positioning <A HREF="../../../com/sun/lwuit/layouts/package-summary.html"><CODE>com.sun.lwuit.layouts</CODE></A>, containers can be nested
            deeply in a similar way to Swing/AWT. All components are lightweight and drawn by
            the <A HREF="../../../com/sun/lwuit/plaf/UIManager.html" title="class in com.sun.lwuit.plaf"><CODE>UIManager</CODE></A> which allows us to theme everything using
            styles. It also alows elaborate UI customizability by deriving <A HREF="../../../com/sun/lwuit/plaf/LookAndFeel.html" title="class in com.sun.lwuit.plaf"><CODE>LookAndFeel</CODE></A>
            and overriding specific methods for drawing/sizing components.
