I am just not getting the new Event handling. I have went over every
example I can find, but it is not clicking. How do you let composite
widgets subscribe to events from other composite widgets? From reading
it sounds like there is a HandlerManager that you register with by
implementing the HasxxHandlers interface, but I cannot piece together
how the Class that creates the event fires it off to the subscribers.
For example I have the following SimpleWidget that extends Composite
that contains a single button. I have another Composite widget that
wishes to be notified when that button is clicked. Can someone fill in
the blanks for me?
(Note I did not attempt to add the event handlers because I do not
want to confuse others who may have the same issue.)
public class SimpleWidget extends Composite{
private Button button;
public SimpleWidget() {
FlowPanel fp = new FlowPanel();
button = new Button("Click me");
//With listeners I would create an anonymous inner class
//that fires the click events to registered listeners.
//I don't know how to fire events for handlers
//button.addClickHandler(handler);???
fp.add(button);
initWidget(fp);
}
}
public class DoSomething extends Composite{
public DoSomething() {
FlowPanel fp = new FlowPanel();
SimpleWidget simple = new SimpleWidget();
fp.add(simple);
initWidget(fp);
}
}
