SuggestBox in GWT - The correct way to create and populate.

Hi everyone, its been a while. Here, in this post, I will be discussing about creating, initializing and populating a suggestbox in gwt. Suggestbox is a text box or text area which displays a pre-configured set of selections that match users input.

Suggestbox is similar to an autocomplete search box. Each Suggestbox is associated with a single SuggestOracle. The SuggestOracle is used to provide a set of selections given a specific query string. SuggestBox uses a MultiWordSuggestOracle as its oracle.

Following are the steps to create and populate a SuggestBox and declaration of MultiSuggestOracle.

1) First step is to declare MultiSuggestOracle.

private final MultiWordSuggestOracle oracle = new MultiWordSuggestOracle();

2) Create SuggestBox

@UiField (provided = true) 
SuggestBox sbox = new SuggestBox(oracle);

The important thing to remember is to add (provided = true).

3) Populating the SuggestBox

private void populateSuggestBox() 
    {
List names = new ArrayList();

names.add("Sujith");
names.add"Mohan");
names.add("Justin");
names.add("Range");

          for (String val : names)
        {
            oracle.add(val);
           }
     }

This way a suggestbox can be created and populated in gwt.
