072:         * Floating window inherits its component properties and shaped panel properties from the root

077:         *
078:         * <p>
079:         * A floating window is created by calling the

084:         *

086:         * It's possible to add a menu bar to the floating window. Just call:
087:         * </p>
088:         * <pre>
089:         *   myFloatingWindow.getRootPane().setJMenuBar(myMenuBar);

091:         *
092:         * <p>
093:         * The floating window is placed as the BorderLayout.CENTER component of the content pane of the
094:         * root pane. You can add additional components in the other BorderLayout positions. Example, add a
095:         * status label at the bottom:
096:         * </p>
