I've been toying around with a diagramming tool that is based of the
SchemaEditor GEF example. My app has roughly the same structure as the
schema editor example, but I require connections to anchor to the edge of
the 'table' figure at the height of the 'column' figure. This required me
to implement a new AbstractConnectionAnchor subclass to provide the anchor
point.
Now, my connections all seem to show up, and away from the source figure
they route nicely around other 'table' figures to the target 'table'
figure. However, at the source 'table' figure, the connection runs right
through the figure if the target figure is not completely to one side or
the other. I've attached a small screen capture of my diagram that shows
the problem (as a uuencoded gif file).
I've debugged this quite a bit, but can't see what the problem is. It
looks like the routing algorithm simply doesn't consider the source
figure, but does consider any figures further out. Note, I'm using GEF
3.0.1 and eclipse platform 3.0.1.
Thanks in advance for any help on this.
