JApplication

java.lang.Object
- app.JApplication

All Implemented Interfaces:

java.awt.event.WindowListener, java.lang.Runnable, java.util.EventListener, javax.swing.RootPaneContainer
```
public abstract class JApplication
extends java.lang.Object
implements javax.swing.RootPaneContainer, java.lang.Runnable, java.awt.event.WindowListener
```
A JApplication is a swing application that looks and behaves like a JApplet.
Specializations of this class must implement the init() method. They may also implement the destroy(), start(), and stop() methods.
