class GetViewRef

Defined at line 177 of file fidling/gen/sdk/fidl/fuchsia.ui.composition/fuchsia.ui.composition/cpp/fidl/fuchsia.ui.composition/cpp/markers.h

Hanging get to receive the ViewRef of the child View. This will only fire when the View ref

is different from the previously-returned View ref. Note: currently the View ref will not

change after it is first received, but this will change if/when the API changes to allow

relinking of views.

The ViewRef is not returned until the View is included in the View tree, in other words when

there is a chain of ancestor transforms all the way back up to the root of the scene graph,

i.e. the display.

It is invalid to call `GetViewRef` while a previous call is still pending. Doing so will

cause both this channel and the Flatland channel that handed out ChildViewWatcher to be

closed.

A `GetViewRef` call will hang if the View was created using `CreateView`, but returns the

View if the View was created using CreateView2. This is because `CreateView` does not mint

a ViewRef for that View.
