There's a ton of ways to do it really. You could implement the event
handlers in each item, in the scene, in the view or using an
eventfilter on either the view or the scene.

Most times I'd say it's cleaner to not use an eventfilter and most times
I'd recommend using the event handlers in the items or in the scene
simply because that's likely to be closer to the logic of your app
than the view but these are just my preferences.
