To configure your project to use Ext GWT (GXT), you can either follow the instructions in the setup.txt file in the Ext GWT download, or you can select your GWT module file and right-click to select the Google Web Toolkit > Configure for using Ext GWT (GXT) command. This will add the gxt.jar to your classpath and module file and various GXT files to your war folder.

In addition to standard types events, Ext GWT (GXT) includes a large number of untyped events which can be configured by right-clicking on the widget and selecting the event type.

button.addListener(Events.Select,
    new Listener<ButtonEvent>() {
    public void handleEvent(ButtonEvent e) {
    }
});

Hold the Ctrl key down to remove an event handler.
