Hi, sorry for re-opening a topic from 2009.
In the above code, you said nameCallback = callBack, where is this
nameCallback being used?
I don't quite understand how to use the callback.
I was just wondering if there's a full implementation / example available
on how to extend the SuggestOracle using RPC.
public class MySuggestOracle extends SuggestOracle {
@Override
public void requestSuggestions(Request request, Callback callback) {
}
}
// in my ManageSomePageView.java
TextBox textBox = new TextBox();
horizontalPanel.add(new SuggestBox(new MySuggestOracle(), textBox));
Thanks
Jan
