Dynamic creation of ConnectionAnchors [message #247827]

Hi,

I would like to create a node which can have always an available
ConnectionAnchor (i.e. add new anchor by itself).
For the moment, I have found a solution which consists in adding a
refreshAnchors() method which is called by refreshVisuals() method. The
first connection is OK but the problem with this solution comes when you
want to draw a second connection : the connection cannot find the location
of the second anchor! Indeed refreshVisuals() method (of the NodeEditPart)
is not called and I need to move or resize the NodeFigure if I want to see
the connection to go to the correct location.

I guess I should call refreshAnchors() at the end of the connection but I
do not know where exactly.I have been trying to find a solution for 2
days and now I have any idea how I can solve this problem so my questions
are very simple :
- Which method should call refreshAnchors() ?
- If it is a wrong way to manage this feature, how should I do ?

Thanks,
Matthieu

Hi,
Is there any specialist in connection mechanism in order to explain to me
(or give me information about...)"how I can have a feedback of my
connection to call the method I want to use" ?

The questions of my previous post still need answers so I am listening to
you if you have any piece of information about this topic.

Thanks,
Matthieu
