    Default Unanswered: Listener best practice

    Unanswered: Listener best practice


    Is it generally considered best practice to add listeners for UI interaction (button presses/list item taps/etc) within a controller or within the views themselves?

    Kind of depends. The logic needs to be in the controller so you can put the listeners and logic in the controller. The only reason why I would say you can listen for it in a view (minus not using MVC) is to fire a custom event. I have created a container which has many children but I don't want the controller to have too intiment knowledge of how a view is structured so I have the container listen for events on it's children and then fire a custom event on itself. Then if I ever have to change the layout on that container, I only have to change the view not find where that logic is implemented in any controller.

    That makes sense. So your controller would still listen for your custom event, but the view would handle capturing the component event and translating it to your custom event, correct?

    Yes, correct. Basically turning that container into a fully fledged widget that can handle itself apart from an application.
