/**
* 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>. From the older <code>java.awt.Window</code> object
* you would normally do something like this:
* <PRE>
* dialog.add(child);
* </PRE>
* Using <code>JDialog</code> the proper semantic is:
* <PRE>
* dialog.getContentPane().add(child);
* </PRE>
* The same principle holds true for setting layout managers, removing
* components, listing children, etc. All these methods should normally be
* sent to the <code>contentPane</code> instead of to the <code>JDialog</code>.
* 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.
* <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>
* For the keyboard keys used by this component in the standard Look and
* Feel (L&F) renditions, see the
* <a href="doc-files/Key-Index.html#JDialog"><code>JDialog</code> key assignments</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}.
