Hello Friends,

I have a window with more than one containers (say 5 containers).

Container1 have a list of jobs that must be assigned to Crews.

Container2 contains 3 containers ( say Crew1, Crew2, Crew3).

When I drag a job from the Container1 and move over Crew1 or Crew2 or
Crew3, the DragSource Feedback figure must resize with respect to a
given value and also must change it color.

Please direct me

Thanks in advance

Justin

showSourceFeedback(Request) will be invoked on the EditPart being dragged,
which will forward it to its EditPolicies. For the logic example, it's the
NonResizableEditPolicy that handles showing the source feedback. You can
show and update the feedback however you want in that method. You should be
able to get all the information you need from the request.
