That's exactly how listeners work. Let's say you have a Button,
TextBox and a Label. Each time the Button is pressed, you want the
Label to display the text in the TextBox. You would do some like the
following:
TextBox text = new TextBox();
Label display = new Label();
Button button = new Button();
// now you need to add the listeners
button.addClickListener(new ClickListener() {
onClick(Widget arg0) {
display.setText(text.getText());
}
});
RootPanel.add(text);
RootPanel.add(display);
RootPanel.add(button);
Keep in mind that if you want the TextBox and the Label to be
accessible from the anonymous inner class, you'll need to make them
fields or final (they can't be local variables).
