Connection routing style while drawing [message #57798]

Originally posted by: tim.rti.com

In my application, a user can add rectangles as well as make connections
between rectangles. Ideally, when a user makes connections, the connection
will be rectilinear, avoiding obstacles.

I modified my connector editpart (extends ConnectionNodeEditPart)
createConnectionFigure method with the following code:

RoutingStyle style = (RoutingStyle) ((View) getModel())
..getStyle(NotationPackage.eINSTANCE.getRoutingStyle());

style.setAvoidObstructions(true);
style.setRouting(Routing.RECTILINEAR_LITERAL);

The problem is, when a user clicks on a rectangle and starts to drag away
from it, there is a straight dotted line that appears. Is there any way to
make this dotted line also rectilinear and avoid obstacles?

Thanks in advance!

I don't know of an easy solution for this but you may want to watch:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=158844

If this extension point is exposed then you may be able to add your own
router or possibly extend another with the functionality that you need.
GEF's ShortestPathConnectionRouter seems to be a step in the direction
that you want to go.
