Dialog Introduction
- A dialog can be either modal or modeless.
- A modal dialog blocks user input to all other windows in the same application when it is visible. You have to close a modal dialog before other windows in the same application can get focus.
- A modeless one does not block user input.
- A dialog can belong to another dialog or a frame. Or, it can stand alone like a JFrame.

Extending JDialog
<p>If you need to extend JDialog, the class has two protected methods of importance:
<source lang="java">
protected void dialogInit() protected JRootPane createRootPane()</source>
extends JDialog to create your own dialog
