Struct ViewProxy

pub struct ViewProxy { /* private fields */ }

Implementations§

impl ViewProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.ui.views/View.

pub fn take_event_stream(&self) -> ViewEventStream

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

§Panics

Panics if the event stream was already taken.

pub fn present(&self, view_token: ViewToken) -> Result<(), Error>

Provides the View with an attachment point to Scenic’s scene graph.

When Present() is called the View’s implementation should create a View resource within Scenic by providing it with the view_token (using a fuchsia.ui.gfx.CreateResourceCmd and fuchsia.ui.gfx.ViewArgs).

Then the implementation should attach its graphical content to the newly-created View resource using a fuchsia.ui.gfx.AddChildCmd.

If the implementation already owns a View resource (because Present() had already been called before), then it should terminate the connection with an error.

TODO(https://fxbug.dev/42098670): Allow re-parenting Views with a new Present() call.
