What a toolbar item is. The variants are the vocabulary every desktop toolbar shares; each backend realizes one with its native control, never with a drawn imitation.

Variants

Button

A push button running the item’s action.

Toggle

A two-state button. on seeds it; the user flipping it emits ToolbarValue::On, and the app’s own writes arrive as ToolbarPatch::On.

Fields

on: bool

Menu

A button that drops a menu: the same MenuItem model the menu bar uses, so a toolbar menu and its menu-bar twin are one list of commands.

Fields

items: Vec<MenuItem>

Search

A search field. Edits emit ToolbarValue::Text; the app’s own writes arrive as ToolbarPatch::Text.

Day creates this item itself, from a .searchable() surface whose placement resolved to the toolbar (docs/search.md); apps declare search on the surface, never here.

Fields

text: String

placeholder: String

suggestions: Vec<String>

Completions for the current text, drawn by the field’s own completion affordance where it has one (AutoSuggestBox, QCompleter, <datalist>). Empty = none.

Segmented

A row of mutually exclusive choices drawn as one control: the native segmented control (NSSegmentedControl, a linked GTK/Qt button box, a XAML toggle strip, .day-segmented on the web).

This is what a set of related toolbar toggles should be when exactly one of them is on at a time: three separate toggles say “three independent switches” to the eye and to a screen reader, and leave the app to keep them exclusive. Choosing a segment emits ToolbarValue::Selected; the app’s own writes arrive as ToolbarPatch::Selected.

Fields

segments: Vec<ToolbarSegment>

One entry per segment. A segment with an icon draws it in place of its title where the platform does that, and keeps the title as its accessible name.

selected: usize

Label

Static text, for a status or a caption.

Separator

A divider between neighbors in the same placement bucket, where the platform draws one (macOS toolbars have no separator, so AppKit renders it as a fixed space, docs/toolbars.md). Grouping is all it does: alignment is ToolbarPlacement’s job.
