/**
* An implementation of a scrollable menu -- a popup window containing
* <code>JMenuItem</code>s that is displayed when the user selects an item on
* the <code>JMenuBar</code>. In addition to <code>JMenuItem</code>s, a
* <code>JMenu</code> can also contain <code>JSeparator</code>s.
* <p>
* In essence, a menu is a button with an associated <code>JPopupMenu</code>.
* When the "button" is pressed, the <code>JPopupMenu</code> appears. If the
* "button" is on the <code>JMenuBar</code>, the menu is a top-level window.
* If the "button" is another menu item, then the <code>JPopupMenu</code> is
* "pull-right" menu.
*
* If the menu contains more items than displayable on the screen the menu
* becomes scrollable by hiding some of the items and adding an add and a down
* arrow at both ends of the menu to scroll the menu with this arrows.
*
* description: A popup window containing menu items displayed in a menu bar.
