| /** |
| * The main class for creating a dialog window. You can use this class |
| * to create a custom dialog, or invoke the many class methods |
| * in {@link JOptionPane} to create a variety of standard dialogs. |
| * For information about creating dialogs, see |
| * <em>The Java Tutorial</em> section |
| * <a |
| href="http://docs.oracle.com/javase/tutorial/uiswing/components/dialog.html">How |
| * to Make Dialogs</a>. |
| * |
| * <p> |
| * |
| * The {@code JDialog} component contains a {@code JRootPane} |
| * as its only child. |
| * The {@code contentPane} should be the parent of any children of the |
| * {@code JDialog}. |
| * As a convenience, the {@code add}, {@code remove}, and {@code setLayout} |
| * methods of this class are overridden, so that they delegate calls |
| * to the corresponding methods of the {@code ContentPane}. |
| * For example, you can add a child component to a dialog as follows: |
| * <pre> |
| * dialog.add(child); |
| * </pre> |
| * And the child will be added to the contentPane. |
| * The {@code contentPane} is always non-{@code null}. |
| * Attempting to set it to {@code null} generates an exception. |
| * The default {@code contentPane} has a {@code BorderLayout} |
| * manager set on it. |
| * Refer to {@link javax.swing.RootPaneContainer} |
| * for details on adding, removing and setting the {@code LayoutManager} |
| * of a {@code JDialog}. |
| * <p> |
| * Please see the {@code JRootPane} documentation for a complete |
| * description of the {@code contentPane}, {@code glassPane}, |
| * and {@code layeredPane} components. |
| * <p> |
| * In a multi-screen environment, you can create a {@code JDialog} |
| * on a different screen device than its owner. See {@link java.awt.Frame} for |
| * more information. |
| * <p> |
| * <strong>Warning:</strong> Swing is not thread safe. For more |
| * information see <a |
| * href="package-summary.html#threading">Swing's Threading |
| * Policy</a>. |
| * <p> |
| * <strong>Warning:</strong> |
| * Serialized objects of this class will not be compatible with |
| * future Swing releases. The current serialization support is |
| * appropriate for short term storage or RMI between applications running |
| * the same version of Swing. As of 1.4, support for long term storage |
| * of all JavaBeans™ |
| * has been added to the {@code java.beans} package. |
| * Please see {@link java.beans.XMLEncoder}. |
