Struct WidgetRunner

Source

pub struct WidgetRunner<A: Clone + 'static> { /* private fields */ }

Expand description

Represents an widget Handler<A> caller that manages the async tasks if needed.

See Handler::into_wgt_runner for more details.

Implementations§

Source §

impl<A: Clone + 'static> WidgetRunner<A>

Source

pub fn event(&mut self, args: &A)

Call HandlerExt::widget_event and start UI task is needed.

Source

pub fn update(&mut self)

Update async tasks.

UI node implementers must call this on UiNodeOp::Update. For preview events before delegation to child, for other after delegation.

Source

pub fn deinit(&mut self)

Drop pending tasks.

Dropped tasks will log a warning.

UI node implementers must call this on UiNodeOp::Deinit, async tasks must not run across widget reinit.
