Struct Action

pub struct Action<Message> { /* private fields */ }

Available on crate feature wgpu only.

A runtime action that can be performed by some widgets.

Implementations

impl<Message> Action<Message>

pub fn capture() -> Action<Message>

Creates a new “capturing” Action. A capturing Action will make other widgets consider it final and prevent further processing.

Prevents “event bubbling”.

pub fn publish(message: Message) -> Action<Message>

Creates a new Action that publishes the given Message for the application to handle.

Publishing a Message always produces a redraw.

pub fn request_redraw() -> Action<Message>

Creates a new Action that requests a redraw to happen as soon as possible; without publishing any Message.

pub fn request_redraw_at(at: Instant) -> Action<Message>

Creates a new Action that requests a redraw to happen at the given Instant; without publishing any Message.

This can be useful to efficiently animate content, like a blinking caret on a text input.

pub fn and_capture(self) -> Action<Message>

Marks the Action as “capturing”. See Self::capture.

pub fn into_inner(self) -> (Option<Message>, Option<RedrawRequest>, Status)

Converts the Action into its internal parts.

This method is meant to be used by runtimes, libraries, or internal widget implementations.
