Showing feedback based on target part [message #233978] Tue, 08 May 2007 23:13

I am trying to get DnD to work in my diagram. I have several parts
in a row and I want to be able to drag one of them across the row and
show feedback (different cursor) if it is valid or not to drop them if a
certain attribute matches. At this point, I am only able to get called
for the source element, not the targets. I thought that I could just
install a NonResizeableEditPolicy as a SELECTION_FEEDBACK_ROLE and get
the appropriate calls there, but for some reason, this prevents the
ghost feedback figure from showing (even though the right methods seem
to be getting called). Also, from the doc, it seems that a REQ_HOVER
request should be sent when hovering over a part, but I'm not getting
that request.

Any help with this would be greatly appreciated.
