Hello.
I'm having some trouble understanding the new event handlers.
When creating a composite A containing widgets B and C, I want
different events from B and C to create a ValueChangeEvent on A. This
way other widgets using A can handle one event instead of two.
A - ValueChangeHandler
B - KeyUpHandler
C - ChangeHandler
What's the best way to do this?
class A extends Composite implements HasValueChangeHandlers<String> {
private Panel container;
private TextBox B;
private ListBox C;
A() {
B.addKeyUpHandler(....?....);
C.addChangeHandler(....?.....);
container.add(B);
container.add(C);
initWidget(container);
}
public HandlerRegistration addValueChangeHandler
(ValueChangeHandler<String> handler) { ....?..... };
}
