 *
 * Zaval Light-Weight Visual Components Library (LwVCL) is a pure Java
 * alternative to humble AWT-based and SWING-based GUI interfaces for
 * wide ranges of platforms, including J2SE, PersonalJava and J2ME.
 *
 * Designed as light-weight but, alternatively to Swing, built separately
 * from AWT (not on top of the java.awt library like Swing), the LwVCL is
 * the good alternative to highly performant, memory-efficient, flexible
 * GUI solution for embedded, stand-alone and applet applications.
 *
 * For more info on this product read Zaval Light-Weight Visual Components Library Tutorial

 * The latest product version is always available from the product's homepage:
 * http://www.zaval.org/products/lwvcl/
 * and from the SourceForge:

/**
 * This is status bar light weight component. The component is a light weight container that
 * uses special layout manager to place status bar components, so don't set any other
 * layout manager for the container. The container layouts child components according to
 * it percentage constraint. The constraint should be passed to <code>add</code> or
 * <code>insert</code> methods of the container as an Integer object where the int value
 * defines the percent. The percent determines width of the child relatively the container width.
 * The sample below illustrates the component usage
 * <pre>
 *   ...
 *   LwStatusBar status = new LwStatusBar();
 *   status.add (new Integer(30), new LwLabel("Label 1"));
 *   status.add (new Integer(70), new LwLabel("Label 2"));
 *   ...
 * </pre>
 * <p>
 * The child components should have identical borders, so the component has special
 * <code>setBorderView</code> method that defines the common border view. The view
 * will set for all added components.
