A SelectionEditPolicy which manages a List of handles provided by the
subclass. Handles are Figures which are added to the HANDLE layer, and
generally return a DragTracker for dragging them. Handles are accessible for
keyboard use if they return an accessible location.
SelectionHandlesEditPolicy implements
IAdaptable
for accessibility support. If any
of the managed Handles provide accesible locations, then a
AccessibleHandleProvider
is automatically created.
