How to access SuggestionMenu.getNumItems() from outside of a SuggestBox context?

[membersound]

HI,

I have a SuggestBox, and want to know how many items are currently displayed.
There is a private int SuggestionMenu.getNumItems() which would return this number. How can I access this or similar method to return the suggestions list size?

Copy this class in your project and modify this method and make it public.

SuggestBox has so many dependencies, also some protected which means I would have to copy a whole bunch of original gwt classes in my project. That's no option...

SuggestionDisplay's showSuggestions is passed the Collection of suggestions, you can thus easily extend DefaultSuggestionDisplay  and store the collection's size in a field to retrieve it later.

Thanks Thomas, I already have an extended SuggestionDisplay, so I implemented your hint and it now works as expected!
