Overview

Single-select from a fixed Array(FormEnumOption), tracked by @focus_index — focus and selection are the same thing here, unlike FlagsField where they're independent. Wire format is the focused option's wire_value (see #value/#start); #value falls back to "" if @options is empty or @focus_index is somehow out of range, rather than raising. Up/Down move focus; Space or Enter commit; Esc cancels without writing back, per FormField's stated rationale that a picker with nothing chosen yet has no sensible commit value.

Instance Method Summary

• #handle_key(ev : KeyEvent) : Symbol | Nil

  Returns :commit or :cancel once the edit finishes; nil while it's still in progress (the key was consumed either way).

• #render(buffer : Buffer, y : Int32, x : Int32, width : Int32, height : Int32 = 1, focused : Bool = true) : Nil

  Draws this field's current edit state.

• #start(current_value : String) : Nil

  Loads a persisted wire-value string into this field's edit state.

• #status_hint : String

  Fragment of a host's status-bar hint describing this field's own key bindings while it's being edited — owned here (rather than left for a host to re-derive per kind) so the bindings shown to the user can never drift from what #handle_key actually does.

• #value : String

  The composed value after a :commit result.
