The "Show more…" use case is already covered by SuggestBox without resorting to hacks like returning a special Suggestion: use setMoreSuggestions(true) on the Response. Rendering is then done by the SuggestionDisplay. The DefaultSuggestionDisplay ignores the info, but you can provide your own SuggestionDisplay. If you don't want to implement one from scratch, you can easily add the functionnality to DefaultSuggestionDisplay: override decorateSuggestionList to wrap the menu in a container where you add a "Show More" button and then override setMoreSuggestions to show/hide the button. Alternately, but a bit hackish, you can simply get a handle on the widget in decorateSuggestionList and cast to a Menu widget, and in setMoreSuggestions dynamically add a "Show More" MenuItem to the menu. The way you handle the click on "ShowMore" is up to you. You could e.g. create a Request with a different "limit", call your SuggestOracle and then call showSuggestions of your SuggestionDisplay with the result. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
