Expand description

Shared behavior of component controller types.

Required Methods§

source

fn sender(&self) -> &Sender<C::Input>

Provides access to the component’s sender.

source

fn state(&self) -> &StateWatcher<C>

Provides access to the state of a component.

Returns the root widget of the component.

source

fn detach_runtime(&mut self)

Dropping this type will usually stop the runtime of the component. With this method you can give the runtime a static lifetime. In other words, dropping the controller or connector will not stop the runtime anymore, instead it will run until the app is closed.
