public static class Component.Event
extends ConnectorEvent

Superclass of all component originated events.

Events are the basis of all user interaction handling in Vaadin. To handle events, you provide a listener object that receives the events of the particular event type.

 Button button = new Button("Click Me!");
 button.addListener(new Button.ClickListener() {
     public void buttonClick(ClickEvent event) {
         getWindow().showNotification("Thank You!");
     }
 });
 layout.addComponent(button);
 

Notice that while each of the event types have their corresponding listener types; the listener interfaces are not required to inherit the Component.Listener interface.
