/**
|
|
* 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://java.sun.com/docs/books/tutorial/uiswing/components/dialog.html">How
|
|
* to Make Dialogs</a>.
|
|
*
|
|
* <p>
|
|
*
|
|
* The <code>JDialog</code> component contains a <code>JRootPane</code>
|
|
* as its only child.
|
|
* The <code>contentPane</code> should be the parent of any children of the
|
|
* <code>JDialog</code>.
|
|
* As a convenience <code>add</code> and its variants, <code>remove</code> and
|
|
* <code>setLayout</code> have been overridden to forward to the
|
|
* <code>contentPane</code> as necessary. This means you can write:
|
|
* <pre>
|
|
* dialog.add(child);
|
|
* </pre>
|
|
* And the child will be added to the contentPane.
|
|
* The <code>contentPane</code> is always non-<code>null</code>.
|
|
* Attempting to set it to <code>null</code> generates an exception.
|
|
* The default <code>contentPane</code> has a <code>BorderLayout</code>
|
|
* manager set on it.
|
|
* Refer to {@link javax.swing.RootPaneContainer}
|
|
* for details on adding, removing and setting the <code>LayoutManager</code>
|
|
* of a <code>JDialog</code>.
|
|
* <p>
|
|
* Please see the <code>JRootPane</code> documentation for a complete
|
|
* description of the <code>contentPane</code>, <code>glassPane</code>,
|
|
* and <code>layeredPane</code> components.
|
|
* <p>
|
|
* In a multi-screen environment, you can create a <code>JDialog</code>
|
|
* 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<sup><font size="-2">TM</font></sup>
|
|
* has been added to the <code>java.beans</code> package.
|
|
* Please see {@link java.beans.XMLEncoder}.
