connecting a connection [message #80496] Thu, 22 May 2003 15:33 Go to next message

Hello NG,

in my project I need to create connections between other connections or
between a connection and a figure. I added the required methods to the
connection-model, the connection-editpart and so on (just like in the models
and editparts of my connectable figures) and created an anchor for each new
connection-figure. If I try to connect these connections, the
ConnectionCommand is executed with the correct source, target and anchors,
but no connection is created. If I try to connect a connection and a figure,
the new connection is created between figure's anchor and the point(0,0) (it
looks just like the target anchor is null but I'm sure it isn't).

Has anyone any idea?

regards,

J

Sounds like NodeEditPart interface is not completely implemented on the
connection which is also a node?

when the new connectionEditPart is created, it will refresh and try to
obtain the ConnectionAnchors for source and target ends. Try putting
breakpoints in AbstractConnectionEditPart#getSource/TargetConnectionAnchor( )

I implemented the NodeEditPart - interface, just like in my FigureEditPart
(get/setSource/TargetConnectionAnchor(request/connection)... )

> Try putting breakpoints in
AbstractConnectionEditPart#getSource/TargetConnectionAnchor( )

This seems to be the problem. If the node is a connection,
AbstractConnectionEditPart#getSource/TargetConnectionAnchor( ) is never
called.
