There appears to be no way to set the focused item in a Flex after initialization. I tried adding stuff like

func (f *Flex) FocusItem(p Primitive) *Flex {
	for _, item := range f.items {
		item.Focus = item.Item == p
	}
	return f
}
``` but didn't have desired effect

I'm not quite sure I understand. (Your code appears to extend this package which confuses me.)

The Flex.AddItem() function includes a parameter focus which can be set to true to give it focus. If you don't know at that time which element should have focus, you can always use Application.SetFocus() later and provide your flex item.

Let me know if this clarifies it for you. If not, it would help to see some example code that illustrates your issue.

I'll reopen if it turns out this is not yet resolved.
