A SelectionEditPolicy which manages a List of handles provided by the subclass. Handles are Figures which are added to the HANDLE layer, and generually 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.
