Class Overview
Subclass for observing changes to the focus state of an WindowId
.
You should use the same instance of this class for observing multiple
WindowId
objects, since this class is fairly heavy-weight -- the
base class includes all of the mechanisms for connecting to and receiving updates
from the window.
