37 * DesktopManager implementation for Aqua
38 *
39 * Mac is more like Windows than it's like Motif/Basic
40 *
41 * From WindowsDesktopManager:
42 *
43 * This class implements a DesktopManager which more closely follows
44 * the MDI model than the DefaultDesktopManager. Unlike the
45 * DefaultDesktopManager policy, MDI requires that the selected
46 * and activated child frames are the same, and that that frame
47 * always be the top-most window.
48 * <p>
49 * The maximized state is managed by the DesktopManager with MDI,
50 * instead of just being a property of the individual child frame.
51 * This means that if the currently selected window is maximized
52 * and another window is selected, that new window will be maximized.
53 *
54 * @see com.sun.java.swing.plaf.windows.WindowsDesktopManager
