Struct OverlayHost 

pub struct OverlayHost { /* private fields */ }

Window-level modal stack + toast queue. Create with cx.new(OverlayHost::new) and render it as the last child of the root.

Implementations

impl OverlayHost

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

pub fn toast_stack(&self) -> Entity<ToastStack>

The inner ToastStack, for duration/clear/remove control.

pub fn toast( &mut self, message: impl Into<SharedString>, cx: &mut Context<'_, Self>, )

Push a plain toast.

pub fn toast_titled( &mut self, title: impl Into<SharedString>, message: impl Into<SharedString>, color: ColorName, cx: &mut Context<'_, Self>, )

Push a titled, colored toast.

pub fn open_modal<E>( &mut self, window: &mut Window, cx: &mut Context<'_, Self>, builder: impl Fn(ModalCloser, &mut Window, &mut App) -> E + 'static, ) -> usize

where E: IntoElement,

Open a modal above everything (stacked above any already open). The builder is re-invoked every frame (live content) and receives a ModalCloser to wire to its close affordances. Returns the modal’s id for close_modal.

Whatever was focused when the modal opened is refocused when it closes; Escape (with focus anywhere inside the modal) closes it.

pub fn close_modal( &mut self, id: usize, window: &mut Window, cx: &mut Context<'_, Self>, )

Close a modal by id, restoring the focus it captured on open.

pub fn close_top(&mut self, window: &mut Window, cx: &mut Context<'_, Self>)

Close the top-most modal, if any.

pub fn modal_count(&self) -> usize
