class Context
Defined at line 1852 of file fidling/gen/sdk/fidl/fuchsia.ui.pointerinjector/fuchsia.ui.pointerinjector/cpp/fidl/fuchsia.ui.pointerinjector/cpp/wire_types.h
The region from which injection is attempted for injected events. As the
context, it serves two purposes:
(1) Scoping. It confirms the |Device|'s authority to inject pointer events
on the specified target. Specifically, the context must be a view-tree
ancestor of the target.
(2) Coordinate System. It provides the reference coordinate system to define
the viewport's position and size, relative to the target.
