Struct TabSwitcher 

pub struct TabSwitcher { /* private fields */ }

A Cmd+Tab-style overlay: a plain list of open items (no search query), navigated with ↑/↓ (or Tab/Shift-Tab to cycle) and confirmed with Enter. Esc requests dismissal via TabSwitcher::on_dismiss.

Deliberately NOT built on crate::CommandPalette/PickerDelegate generic abstraction — with only these two overlay use-cases in the codebase so far, a second bespoke ~150-line file is cheaper than generalizing early (YAGNI). Revisit if a third picker-shaped overlay (file-finder, go-to-line) shows up.

Caller-owned open/closed state, matching CommandPalette/Modal/Drawer: there is no internal open flag. The caller mounts a TabSwitcher into the tree only while it should be visible.

Implementations

impl TabSwitcher

pub fn new(cx: &mut Context<'_, Self>, items: Vec<TabSwitcherItem>) -> Self

pub fn on_dismiss( self, handler: impl Fn(&mut Window, &mut App) + 'static, ) -> Self

Registers a callback invoked when the user presses Esc, requesting that the caller unmount/close this switcher.

pub fn focus(&self, window: &mut Window, cx: &mut App)

Moves keyboard focus onto the switcher so Tab/↑/↓/Enter/Esc work immediately. Callers should invoke this once after mounting.

Trait Implementations

impl Focusable for TabSwitcher

fn focus_handle(&self, _cx: &App) -> FocusHandle

Returns the focus handle associated with this view.

impl Render for TabSwitcher

fn render( &mut self, _window: &mut Window, cx: &mut Context<'_, Self>, ) -> impl IntoElement

Render this view into an element tree.
