Connection creation customization [message #226451]

Hi,

I created a basis diagram and want to enhance this now but I have a few
problems doing this.

The first thing is the connection between to figures. The figure has a
rectangle on top and a vertical line beneath. I want to specify that only
the line can be used to dock the connection. Currently the connection can
be done starting from every point. Also a bad thing about this is the big
spacing between the connection polyline and the two vertical figure lines.
This occurs because of the width of the rectangle which is wider than the
polyline. How can I specify that the connection starts and ends directly
at the line figure?

The second problem are also related to the connections. If I add a
connection I want that they all have the same spacing to the brother
connection and that the connections are sorted based on a specific value
from the domain model. If I am right I have to define a custom
layoutmanager for this. The problem then is the vertical polyline of the
base figure, this should be resized if there is not enough space left to
add a connection with the static spaceing. How could I implement this?

Regards,
Tobias

Hello Tobias,

Are you working on sequence diagram? ;-)

I think you have to customize ConnectionAnchors by changing supclass of NodeFigure
used as a figure for diagram element.

Again I hope you can do that with the connection anchors.
