Struct GraphicalPresenterProxy

pub struct GraphicalPresenterProxy { /* private fields */ }

Implementations

impl GraphicalPresenterProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.element/GraphicalPresenter.

pub fn take_event_stream(&self) -> GraphicalPresenterEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn present_view( &self, view_spec: ViewSpec, annotation_controller: Option<ClientEnd<AnnotationControllerMarker>>, view_controller_request: Option<ServerEnd<ViewControllerMarker>>, ) -> QueryResponseFut<GraphicalPresenterPresentViewResult, DefaultFuchsiaResourceDialect>

Presents the view described by view_spec.

If view_controller_request is provided, it will be connected to a ViewController implemented by the GraphicalPresenter server. When the view is dismissed, the ViewController channel is closed with a ZX_OK, at which point it is safe to clean up resources backing the view. To dismiss the view, the client should call ViewController.Dismiss() and wait for the ZX_OK epitaph. Not providing a view_controller_request handle will make it impossible for the client to observe the view’s lifecycle.

• view_spec describes the view to present
• annotation_controller a handle to an AnnotationController, allowing the GraphicalPresenter server to observe and update the view’s annotations.
• view_controller_request an optional request for a controller for the view

• error view_spec must contain view_holder_token and view_ref for Gfx views, OR viewport_creation_token for Flatland views, but never both. If both are set, error PresentViewError.INVALID_ARGS is returned.
• error PresentViewError.INVALID_ARGS if spec.view_holder_token or spec.view_ref are missing or invalid.
