Drag and Drop Available Target Indicator

      Disclosed is a technique to provide greater feedback to users
regarding available target objects during drag and drop operations.

      The conventional approach to indicate available target objects
to the user during drag and drop operations is to wait until the user
has dragged the source object over a target object.  At that point,
the target is emphasized if it is valid or a "not" pointer appears if
it is an invalid operation.  This "wait and see" approach is
inconsistent with the approach in other areas of the interface
(pull-down menus) where unavailable options are grayed once the user
selects the object.  The system does not wait until the user selects
the specific action to indicate an invalid choice.

      A technique is provided to indicate available target status to
the user at the moment a source object is chosen.  Two appearance
changes are provided here.  Others are possible.

      Available target emphasis - once the user has selected a source
object, all valid target objects are emphasized.  For example, a
solid box is placed around them or a shaded box is placed behind
them.

      Unavailable target graying - once the user has selected a
source object, all unavailable target objects are grayed.  This
method provides a consistent approach with that used to gray
unavailable actions on menu bar pull-downs and elsewhere.
