Is there documentation for how to call a javascript function when:

1. In a PageControl when Pages are swiped in or out - e.g. onPageHasFocus/onPageLostFocus?
2. A Control like TextInput has focus or lost focus?

Also, is there a complete list of Triggers?

Sounds like you are looking for the `<Activated>` trigger or `Activated` event for pages, and `<WhileFocusWithin>` for text inputs. You can also use `Focus.Lost` and `Focus.Gained` events.
