Hi, I've tried to add a selection handler to a suggestbox onSelection
where I expect that the Suggestion is my UserSuggestion that extends
IsSerializable and Suggestion but eclipse is having some objections:
The method addSelectionHandler
(SelectionHandler<SuggestOracle.Suggestion>) in the type SuggestBox is
not applicable for the arguments (new SelectionHandler<UserSuggestion>
(){})
suggestBox.addSelectionHandler(new SelectionHandler<UserSuggestion>(){
public void onSelection(SelectionEvent<UserSuggestion>
event) {
Long id = event.getSelectedItem().getId();
RootPanel.get("").add(new Label(id));
}
});
looking at the SuggestBox sources, would a raw type that extends
Suggestion do the trick (and would the gwt compiler know how to
translate to javascript)?
public HandlerRegistration addSelectionHandler(
SelectionHandler<Suggestion> handler) {
return addHandler(handler, SelectionEvent.getType());
}
public HandlerRegistration addSelectionHandler(
SelectionHandler<? extends Suggestion> handler) {
return addHandler(handler, SelectionEvent.getType());
}
