| /** | |
| * 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="https://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}. | |
