This is an example on how to get inout from the Output Window. Just change what's done on the read method (listener implementation) to customize the behavior. Things that come to mind: chat client, text based games, etc...

[source,java]

 * Enable/create the tabs we need for the component

    private final String normal = "Output";

                OutputHandler.output(normal, "Welcome! Type something below.");
                //Create a monitor for the tab. This enables input in the tab as well.
                InputMonitor monitor = OutputHandler.createMonitor(normal);
                //Add a listener to be notified.
                monitor.addListener(Installer.this);
            }
        });
    }

    @Override
