Catch all uncaught exceptions in GUI

Question

Is there a way to catch any uncaught exceptions within my GUI so that I can do some special handling instead of it being echoed to the console?

Answer 1

It's actually an AWT class that's catching the errors: EventDispatchThread. There is a way to override that mechanism, but it's unsupported, and the only place it's documented is in the source code of that class. Here's an example.
public class MyApp
  public static void main(String[] args)
    System.setProperty("sun.awt.exception.handler",
                       "MyApp$EDTErrorHandler");
    // create and show the GUI
   * This class will be instantiated by the
   * EventDispatchThread the first time it
   * encounters an exception or error.
  public static class EDTErrorHandler
     * This method is invoked by the AWT event
     * dispatch mechanism when an unexpected
     * exception or error is thrown during
     * event dispatching.
    public void handle(Throwable t)
      // handle the error
}
