Struct EventHandler 

pub struct EventHandler<T>(/* private fields */);

Implementations

impl<T> EventHandler<T>

pub fn new(handler: impl FnMut(T) + 'static) -> Self

pub fn new_scoped(scope_id: ScopeId, handler: impl FnMut(T) + 'static) -> Self

Create an event handler that runs under the given scope.

APIs that rely on the current scope, like spawn, will use scope_id instead of the scope of the element that received the event.

pub fn new_current(handler: impl FnMut(T) + 'static) -> Self

Create an event handler that runs under the scope creating it.

Shortcut for EventHandler::new_scoped with the current scope, so e.g tasks spawned in the handler are cancelled once the component creating it unmounts.

let on_press = EventHandler::new_current(|_| {
    spawn(async {
        save_document().await;
    });
});

Button::new().child("Save").on_press(on_press)

pub fn call(&self, data: T)
