Host-level event returned by App::next.

Input has already been routed into the retained tree.

Variants

Updated

Routed input changed the tree; the next App::next call presents it.

Key(Key)

A key no component claimed: it routed through the tree untouched — pending damage from animations or other components never masks it — and matched no quit or clipboard chord. Hosts use it for scene-level hotkeys without intercepting the widget path.

Submitted

The focused widget submitted.

Pressed(Str)

An ID-carrying button fired.

Resized(Size)

A resize settled after Ui::resize ran.

Appearance(Appearance)

The terminal background flipped between dark and light. The retained context has already been restyled; hardcoded colors derived outside the theme are the app’s to refresh.

OverlayClosed(OverlayId)

A cancel from inside a layer dismissed the topmost visible overlay.

Highlighted

An ID-carrying select’s cursor rested on a new option.

Fields

id: Str

The select’s id.

value: Str

Value of the option under the cursor.

Changed

An ID-carrying select committed an option.

Fields

id: Str

The select’s id.

value: Str

Value of the committed option.

Filtered

An ID-carrying filterable select’s query changed.

Fields

id: Str

The select’s id.

query: Str

The new filter query.

value: Option<Str>

Value of the option under the cursor after re-filtering.
