I have a second pane which provides additional help on screen -- ideally I'd like to have a callback that occurs when the focused item changes, so that I can provide text relevant to that particular input field. Sort like an OnFocus() function or something.

I'd be happy to have that as a method on the FormItem, but it could also work to do do this in the Form itself.

Primitive and therefore also FormItem has Focus() which is called when it receives focus. Have you tried that?

@rivo commented on GitHub (May 28, 2021): [`Primitive`](https://pkg.go.dev/github.com/rivo/tview#Primitive) and therefore also `FormItem` has `Focus()` which is called when it receives focus. Have you tried that?

Box.SetFocusFunc() exists now. Let me know if this helps you.
