I'm trying to get an event by it's name and I was pointed to the following code:

const TypeClass* type = button3->GetClassType();
const RoutedEvent* clickEvent = Noesis::Gui::FindRoutedEventRecursive(type, clickEventName);

However, FindRuitedEventRecursive's 2nd parameter isn't a string event name, it's some NsSymbol which isn't making sense to me when I look at it's description.

We use symbols internally to avoid comparing strings. A symbol is internally an integer. You can create a symbol from string easily:
Having said that, that function should be getting a string instead of a symbol. We should avoid exposing those details in the public API whenever possible. Will be fixed.

Thanks. While you are at it you may want to change this too in event handlers.

NsSymbol eventName = e.routedEvent->GetName();

Otherwise we have to do:

string eventName = NsSymbol(e.routedEvent->GetName()).GetStr();

Yes, thanks for the feedback.
