- public class GraphicalMessageHandler
- extends MessageHandler
This is a message handler that reports errors in a graphical dialog box.
When an applet or application starts up, it should call setContext()
to specify a component with respect to which the display window
should be created. This ensures that if the application is iconified
or deiconified, that the display window goes with it. If the context
is not specified, then the display window is centered on the screen,
but iconifying and deiconifying may not work as desired.
This class is based on (and contains code from) the diva GUIUtilities
class.
