| 36 | +/** | |
| 37 | + * A <code>JWindow</code> is a container that can be displayed anywhere on the | |
| 38 | + * user's desktop. It does not have the title bar, window-management buttons, | |
| 39 | + * or other trimmings associated with a <code>JFrame</code>, but it is still a | |
| 40 | + * "first-class citizen" of the user's desktop, and can exist anywhere | |
| 41 | + * on it. | |
| 42 | + * <p> | |
| 43 | + * The <code>JWindow</code> component contains a <code>JRootPane</code> | |
| 44 | + * as its only child. The <code>contentPane</code> should be the parent | |
| 45 | + * of any children of the <code>JWindow</code>. | |
| 46 | + * As a conveniance <code>add</code> and its variants, <code>remove</code> and | |
| 47 | + * <code>setLayout</code> have been overridden to forward to the | |
| 48 | + * <code>contentPane</code> as necessary. This means you can write: | |
| 49 | + * <pre> | |
| 50 | + * window.add(child); | |
| 51 | + * </pre> | |
| 52 | + * And the child will be added to the contentPane. | |
| 53 | + * The <code>contentPane</code> will always be non-<code>null</code>. | |
| 54 | + * Attempting to set it to <code>null</code> will cause the <code>JWindow</code> | |
| 55 | + * to throw an exception. The default <code>contentPane</code> will have a | |
| 56 | + * <code>BorderLayout</code> manager set on it. | |
| 57 | + * Refer to {@link javax.swing.RootPaneContainer} | |
| 58 | + * for details on adding, removing and setting the <code>LayoutManager</code> | |
| 59 | + * of a <code>JWindow</code>. | |
| 60 | + * <p> | |
| 61 | + * Please see the {@link JRootPane} documentation for a complete description of | |
| 62 | + * the <code>contentPane</code>, <code>glassPane</code>, and | |
| 63 | + * <code>layeredPane</code> components. | |
| 64 | + * <p> | |
| 65 | + * In a multi-screen environment, you can create a <code>JWindow</code> | |
| 66 | + * on a different screen device. See {@link java.awt.Window} for more | |
| 67 | + * information. | |
| 68 | + * <p> | |
| 69 | + * <strong>Warning:</strong> Swing is not thread safe. For more | |
| 70 | + * information see <a | |
| 71 | + * href="package-summary.html#threading">Swing's Threading | |
| 72 | + * Policy</a>. | |
| 73 | + * <p> | |
| 74 | + * <strong>Warning:</strong> | |
| 75 | + * Serialized objects of this class will not be compatible with | |
| 76 | + * future Swing releases. The current serialization support is | |
| 77 | + * appropriate for short term storage or RMI between applications running | |
| 78 | + * the same version of Swing. As of 1.4, support for long term storage | |
| 79 | + * of all JavaBeans<sup><font size="-2">TM</font></sup> | |
| 80 | + * has been added to the <code>java.beans</code> package. | |
