Widget#fireEvent? (how about looking at how things are done in existing widgets? look specifically for the com.google.gwt.event.logical.shared.* events)

If your goal is to do a treatment when the event occurs on the child widget you must implement the corresponding interface in your custom Widget. for example:

public class MyWidget extends Composite implements HasClickHandlers

{

    private TextBox text = new TextBox();

    private PushButton button = new PushButton("MyButton");

    public MyWidget()

    {

         ....

         initWidget(...);

     }

     @Override

   public HandlerRegistration addClickHandler(ClickHandler handler)

   {

      return button.addClickHandler(handler);

   }

}
