Struct ToolbarEntry 

pub struct ToolbarEntry { /* private fields */ }

A toolbar item under construction. Build a command with toolbar_button, a two-state button with toolbar_toggle, a pull-down with toolbar_menu, a search field with toolbar_search, and the gaps with toolbar_space / toolbar_flexible_space.

Implementations

impl ToolbarEntry

pub fn action(self, f: impl Fn() + 'static) -> ToolbarEntry

Run f when the item is chosen. On a toggle or a search field the value binding carries the change; an action here runs in addition to it.

pub fn icon(self, symbol: Symbol) -> ToolbarEntry

Draw a standard Symbol, using the platform’s own icon set — an SF Symbol on macOS, a freedesktop icon name on GTK and Qt, a Fluent glyph on Windows.

pub fn image(self, name: impl Into<ImageName>) -> ToolbarEntry

Draw a bundled image from resource/images — for an icon only this app has. Prefer ToolbarEntry::icon for anything standard: one PNG cannot look native on four desktops.

pub fn tooltip<M>(self, t: impl IntoText<M>) -> ToolbarEntry

Hover help. Defaults to the item’s label.

pub fn placeholder<M>(self, t: impl IntoText<M>) -> ToolbarEntry

The empty-state prompt of a search item (ignored on other kinds).

pub fn enabled(self, on: bool) -> ToolbarEntry

Enable or disable the item once, at build.

pub fn enabled_when(self, f: impl Fn() -> bool + 'static) -> ToolbarEntry

Enable the item while f reads true, re-evaluated whenever its reactive reads change. This is the live path: it patches the one item rather than rebuilding the bar, so a command greying out never disturbs a search field mid-word.
