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