pub struct ManagerProxy { /* private fields */ }

Implementations

impl ManagerProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.session.scene/Manager.

pub fn take_event_stream(&self) -> ManagerEventStream

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

Panics

Panics if the event stream was already taken.

pub fn set_root_view( &self, view_provider: ClientEnd<ViewProviderMarker>, ) -> QueryResponseFut<ManagerSetRootViewResult, DefaultFuchsiaResourceDialect>

Sets the root view of the scene graph to the view provided by view_provider.

Subsequent calls will replace the view tree with the one starting at the new root view. The root view is shared between all clients of Manager.

Returns a fuchsia.ui.views.ViewRef referencing the view provided by view_provider. If this ViewRef cannot be returned (e.g. in Flatland case, if the ViewCreationToken is dropped before it is given to Scenic), then the connection to the Manager will be closed.

The client can expect that:

(1) Its root view will be focused once it’s connected to the scene. (2) The logical size and position of its root view match the display.

TODO(https://fxbug.dev/42055565): Fix this situation. NOTE: the ViewRef is only returned after the child view is connected to the scene graph. Therefore, the caller must guarantee that the child view will eventually be connected before waiting for the ViewRef; if the child view doesn’t connect, it is possible to deadlock.

pub fn present_root_view_legacy( &self, view_holder_token: ViewHolderToken, view_ref: ViewRef, ) -> QueryResponseFut<ManagerPresentRootViewLegacyResult, DefaultFuchsiaResourceDialect>

Presents a view tree to the display, via the provided view holder token.

This call will present the view using the legacy GFX API.

Subsequent calls will replace the view tree with the one starting at the new root viewport. The root view is shared between all clients of Manager.

The client can expect that:

(1) Its root view will be focused once it’s connected to the scene. (2) The logical size and position of its root view match the display.

TODO(https://fxbug.dev/42055565): Fix this situation. NOTE: this method returns only after the child view is connected to the scene graph. Therefore, the caller must guarantee that the child view will eventually be connected before waiting for the return; if the child view doesn’t connect, it is possible to deadlock.

pub fn present_root_view( &self, viewport_creation_token: ViewportCreationToken, ) -> QueryResponseFut<ManagerPresentRootViewResult, DefaultFuchsiaResourceDialect>

Presents a view tree to the display, via the provided viewport token.

Subsequent calls will replace the view tree with the one starting at the new root viewport. The root view is shared between all clients of Manager.

The client can expect that:

(1) Its root view will be focused once it’s connected to the scene. (2) The logical size and position of its root view match the display.
