Detailed Description

Toolbar leaf widget for the ra8_widget tree model (#145 Phase 2).

The e-reader Library screen carries a toolbar: a wide search field on the left (a bordered box showing a placeholder hint) and a fixed-width count chip on the right (e.g. "12 books"). Tapping the search field opens the on-screen keyboard. ra8_widget_toolbar_t extracts that into a reusable ra8_widget leaf. render fills the band, draws the bordered search field with its hint and the right-aligned count text, all through the injected ra8_widget_paint_t backend (no ra8_gfx dependency). on_input treats the search field as a tap target: a touch inside it bumps searches, self-invalidates fast, and fires the optional on_search callback; a tap on the count chip (or a button event) is declined so it keeps routing.

nodiscard

Bind a widget instance to a toolbar.

Wires w to render + route bar: sets its vtable to ra8_widget_toolbar_vtable, points its ctx at bar, and makes it visible. The caller still sets w's fixed / flex for its parent's layout.

Parameters

[in,out]	w	Widget to turn into a toolbar (non-NULL).
[in]	bar	Toolbar descriptor (non-NULL; outlives `w's` use).

Returns: ra8_err_t

Return values

k_ra8_ok	Bound; `w` renders + routes `bar`.
k_ra8_err_null_ptr	`w` or `bar` is NULL.

Precondition: w and bar are non-NULL.; bar outlives every render / dispatch of w.

Postcondition: On success w->vt == ra8_widget_toolbar_vtable(), w->ctx == bar, w->visible == true.; On failure w is left unchanged.

Note: Not thread-safe.

◆ ra8_widget_toolbar_vtable()

const ra8_widget_vtable_t * ra8_widget_toolbar_vtable ( void )

Return the shared vtable backing every toolbar widget.

One immutable vtable serves all toolbars: render fills the band, the bordered search field + hint, and the count chip through the toolbar's ra8_widget_paint_t; on_input latches a touch inside the search field and declines everything else; measure is NULL. ra8_widget_toolbar_init binds it.

Returns: Non-NULL pointer to the static toolbar vtable.

Precondition: None.; None.

Postcondition: The returned pointer is non-NULL and references static storage.; No state is modified.

Note: Pure; thread-safe (returns a pointer to immutable static data).
