Programatically create connection bend points [message #668289]

Hi,

is there a way to create bend points on a connection programatically and define the bend degree (e.g. 90°) ?

What I am trying to achieve is to create a connection from the right-hand side of an object to its top in order to visualize a recursive connection. This connection should have two 90 degrees bends.

Thanks, Remo

Yes there is, here is how I do this::

protected void addBendPoints(FreeFormConnection freeConnection, int firstX, int firstY, int secondX, int seondY) {
        Point bendpoint1 = Graphiti.getCreateService().createPoint(firstX, firstY);
        Point bendpoint2 = Graphiti.getCreateService().createPoint(secondX, seondY);
        freeConnection.getBendpoints().add(bendpoint1);
        freeConnection.getBendpoints().add(bendpoint2);
    }

If you put the bendpoints at the right places, they will have the required 90 degree .

Hi, I just tryed what you said and Its true. It creates the bending points. The problem is that the X and Y coordinates are global and I am creating the connection inside a container Shape so I Would need to access the local coordinates somehow in order to create a proper connection (it almost goes to the 0,0 and comes back to the target).

Any ideas?

Victor,

the tool behavior provider has methods getAbsoluteLocation that can give you
the location of the container shape, so you could calculate the right
positions. Connection locations are always absolute and refer to the diagram
itself.
