Class GUIExceptionHandler

java.lang.Object
  dip.gui.GUIExceptionHandler

public class GUIExceptionHandler

extends java.lang.Object

Handles uncaught exceptions from an AWT event thread. Note that this class does NOT handle uncaught exceptions from non-AWT event threads!

This is an effective but nonportable (it will not work on non-Sun JVMs, and may not work in future Java versions) of handling uncaught exceptions.

This code was derived from a Java Developer Forum post.

Usage

At the beginning of your application set the System property to the name of your exception handler class:

        System.setProperty("sun.awt.exception.handler" ,"dip.gui.GUIExceptionHandler");
        

Alternatively, this can be done transparently with the registerHandler() method.

When an uncaught exception occurs in the EventDispatchThread, it will check the value of "sun.awt.exception.handler", create an instance of the class and call its handle method.
