PROTOCOLS
Controller
Defined in fuchsia.ui.test.scene/controller.fidl
Controls a UI test scene. Allows a test to attach test Views to the scene and add View-related instrumentation.
AttachClientView
*** NOTE: ViewProvider
is no longer the preferred way for a parent
and child view to agree on a ViewportCreationToken / ViewCreationToken
pair. Flatland-based clients are encouraged to use PresentView
(below)
instead of AttachClientView
.
Elicits the server to request a view using the
fuchsia.ui.app.ViewProvider
handle provided, and attach it to the
scene.
RETURN VALUE
This method returns the KOID for the client view's ViewRef
.
SYNCHRONIZATION
This call returns as soon as the client ViewRef
is available. Note
that this signal does NOT necessarily indicate that the view has been
attached to the scene.
LIFE CYCLE
Clients may drop the Controller
connection once AttachClientView
has
returned.

RegisterViewTreeWatcher
Registers a ViewTreeWatcher
on the client's behalf.
The ViewTreeWatcher
registered on behalf of the client will currently
be scoped globally; we intend to restrict the scope to the client view's
subtree as soon as it's feasible to do so.
For more information on geometry observation, see the documentation in //sdk/fidl/fuchsia.ui.observation.geometry/watcher.fidl.
