Re: gwt suggestbox.

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

I don't know if this helps, but I wrote a PersonSugggestOracle that
extends SuggestOracle

The method below calls the server.  It doesn't call the server if
there are not at least 2 characters typed.

On the server side, I have a sql query that uses the characters to
perform a 'like' comparison on the first name, or the lastname so it
works similar to like a multiword suggest oracle.
On the server, I return the Person Name as a small HTML string with
<b></b> tags surround the characters that the user typed to emphasize
the part of the first or last name that is matching. I also limit the
response to 12 matching records on the server.

 @Override
    public void requestSuggestions(Request request, Callback callback)
{
            nameCallback = callback;
            String q = request.getQuery();
            if (q >=2) {
                   asyncRequest.personSuggest(q,submitterId,12,new PersonsReceived
(request));
            }
    }
