class ViewRefInstalled
Defined at line 175 of file fidling/gen/sdk/fidl/fuchsia.ui.views/fuchsia.ui.views/cpp/fidl/fuchsia.ui.views/cpp/markers.h
A method of enabling ViewRef holders to determine if a ViewRef has been
"installed" in the view tree: the time it is first connected, transitively,
to the root view. Typically, after installation, view focus may be
transferred to that ViewRef.
Note: It's important to distinguish between a ViewRef's installed status and
current connected-to-view-tree status. The former undergoes a state
change once, from "no" to "yes". The latter may change continuously,
depending on view tree topology. As such, "installed" cannot imply
"currently connected to view tree"; even a hypothetical
"ViewRefConnected" protocol is fundamentally racy.
