Re: How to fire event

Firing a change event turns out being simple:

package simple.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.event.dom.client.ChangeEvent;
import com.google.gwt.event.dom.client.ChangeHandler;
import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.TextBox;

class OurChangeEvent extends ChangeEvent {}

public class Simple implements EntryPoint {

public void onModuleLoad() {
TextBox textBox = new TextBox();
RootPanel.get().add(textBox);

textBox.addChangeHandler(new ChangeHandler() {
public void onChange(ChangeEvent event) {
Window.alert("got change event on textBox");
}
});
textBox.fireEvent(new OurChangeEvent());
}
}
