UserEvent

Enum UserEvent 

Source
pub enum UserEvent<Msg> {
    Msg(Msg),
    Quit,
    OpenWindow {
        key: u64,
        title: String,
        width: u32,
        height: u32,
    },
    CloseWindow {
        key: u64,
    },
    A11y(Event),
}
Expand description

Mensaje interno del event loop. Msg lo dispara la app desde un hilo de fondo vía Handle::dispatch o Handle::spawn; Quit cierra la ventana y termina el proceso.

Variants§

§

Msg(Msg)

§

Quit

§

OpenWindow

Pide abrir una ventana OS secundaria con la key dada (la app la usa para distinguir cuál es en App::secondary_view). Idempotente: si ya existe una con esa key, se enfoca en vez de duplicar. La crea el event loop (que tiene el ActiveEventLoop); por eso va por mensaje.

Fields

§key: u64
§title: String
§width: u32
§height: u32
§

CloseWindow

Pide cerrar la ventana secundaria con esa key. No afecta a la primaria.

Fields

§key: u64
§

A11y(Event)

Evento del adapter AccessKit: el lector de pantalla solicitó el árbol inicial, pidió ejecutar una acción (focus, click, etc.) o se desactivó. El adapter usa el EventLoopProxy para enviarlos al hilo del runtime.

Trait Implementations§

Source§

fn from(e: Event) -> Self

Converts to this type from the input type.
