| 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. | ||
