In this example we shall show you how to create a com.google.gwt.user.client.ui.SuggestBox example. Google Web Toolkit is an open source set of tools that allows web developers to create and maintain complex JavaScript front-end applications in Java. A SuggestBox is a text box or text area which displays a pre-configured set of selections that match the user’s input. To create a SuggestBox one should perform the following steps:
- The
SuggestBoxExampleclass implements thecom.google.gwt.core.client.EntryPointinterface to allow the class to act as a module entry point. It overrides itsonModuleLoad()method. - We create new HorizontalPanel.
- We create a new
SuggestBox, with thegetCountries()method, that hasMultiWordSuggestOracleobject, where it adds the countries to be set in theSuggestBox. - We create and add new
Labelto theHorizontalPanel. - We add the
SuggestBoxto theHorizontalPaneland then add theHorizontalPanelto theRootPanel, that is the panel to which all other widgets must ultimately be added,
as described in the code snippet below.
