Selectors

Select one or several stable-ID items from a visible list.

The site build compiles the dedicated Ada component example, constructs Selectors through its public API, and exports that exact styled surface. Read the capture source.

When to use it

Use a selector when choices must remain visible or when users can select multiple items.

State and ownership

The Flyology_TUI.Components.Selectors package defines this component.

Single and multiple modes share bounded item storage. The model validates the complete replacement before it changes the selection.

  • The application model owner applies updates during serial event dispatch.
  • Appearance and skin values are borrowed only while the component renders.

Input and updates

Arrows move focus. Space and mouse release toggle according to the configured selection mode.

Integration sequence

  1. Create the bounded model and populate it with caller-owned data.
  2. Route the current keyboard or local mouse event through the component handler.
  3. Apply the typed result, then render from the updated model with the current appearance.

See the linked package reference for its exact declarations and contracts.

Responsive and accessible behavior

  • Use dimensions and regions from the current layout or presentation value.
  • When a component owns mouse capture, route its matching release even when the pointer leaves the original bounds.
  • Retain a glyph, label, border, or text-attribute cue when the terminal reduces color.
