Re: [gef-dev] Connection not touching figure.

You shouldn't need to use multiple figures
to render an Icon+Text.  Label does this.  Then, you can override
the getBox() method in chopbox anchor to return the icon's box.

But, avoiding the text makes me think
this should be a special type of anchor.  You need chopboxes, with
two separate rectangles.

Fergal's answer made me rethink...

The simplest solution, if normal chopbox functionality is good enough for
you -  is to simply pass the correct figure (your inner rectangle)
to the 
ChopboxAnchor constructor :) in your implementation of 
NodeEditPart#getSource/TargetConnectionAnchor.

Usually you create the ChopboxAnchor like so

new ChopboxAnchor(getFigure())

But you can use something like

new ChopboxAnchor(getFigure().getChildren().get(0))  //or whatever
index 
your inner rectangle is in your custom figure.

Sorry for not thinking straight the first time.

Brian.
