TUI::BoolField

Inherits TUI::FormField < Reference < Object

Two-state toggle, rendered as ◉ yes ○ no / ○ yes ◉ no. Wire format is the literal string "true" or "false" (see #value/#start). Left/Right and Space are equivalent ways to flip @bool_pending; Enter and Esc both commit — there's no cancel path, matching FormField's stated rationale that a bool edit has no sensible discard-in-place gesture.

Instance methods

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).

Source

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

Draws this field's current edit state. height bounds how many buffer rows this field may draw into. focused gates any keyboard-cursor decoration that should be suppressed when rendering a persisted value outside an active edit session (only FlagsField uses this — see its #render).

Source

start(current_value : String) : Nil

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

Source

status_hint

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.

Source

value

The composed value after a :commit result.
