Abstract

Disclosed is a method for controlling the order of connections within an object oriented visual builder. A user interface that is appropriate for one user may not make sense to another. Within many object oriented visual builders, a connection is made by drawing a line from a source object to a target object. The user then specifies an event on the source object and a method on the target object. There may be more than one target method for each source event. The order in which target methods are invoked is the order in which the links are created. This order can be changed from within a special editor, but this user interface is not intuitive to some people.

Expose Connection List as Property

      Disclosed is a method for controlling the order of connections
within an object oriented visual builder.  A user interface that is
appropriate for one user may not make sense to another.  Within many
object oriented visual builders, a connection is made by drawing a
line from a source object to a target object.  The user then
specifies an event on the source object and a method on the target
object.  There may be more than one target method for each source
event.  The order in which target methods are invoked is the order in
which the links are created.  This order can be changed from within a
special editor, but this user interface is not intuitive to some
people.

      This problem can be solved by exposing the links associated
with a single source event as a property.  To do this, the links must
be named, and put in a list.  This list can be compiled at the time
that the link is created, and exposed as an object property.  Since
most builders have some type of property editor, this invention can
easily be added to many existing builders.  From within the property
editor, the user first chooses an event and then is presented with a
list of links.  These links can be rearranged by a drag and drop
scheme.  The approach is both intuitive and efficient.
