Hi,

I have a diagram that contains elliptical shapes. When I select them, the
border that is painted around them is rectangular and the connections in
my diagram are routed around the figure as if it was rectangular. Is there
a way to make the border elliptical?

Thanks in advance,

Hi,

To have your connection linked on the ellipse, you must define specific
anchors :
- add interface NodeEditpart on the editpart which control your ellipse
- implement getTargetConnectionAnchor,getSourceConnectionAnchor on the
editPart to return your own anchors.
- see EllipseAnchor.

To have the custom feedback of selection (not a rectangle similar to the
bounds of your figure), try to extend the pocily which manage the
selection (NonResizableEditPolicy, or ResizableEditpolicy)of your figure
and override the createDragSourceFeedbackFigure() and
createSelectionHandles()

Hi,

thanks for your reply! I successfully managed to make the connections go
to the ellipse borders using the EllipseAnchor now. I haven't had time to
test the thing with the custom feedback of selections. But I also have the
problem that connections that don't go to the ellipse elements are routed
around those elements as if the element was rectangular. Do you or someone
else have a solution or idea for that as well?

I suppose that you use the ShortestPathConnectionRouter and the
algorithm which calculate the path uses the bounds of the figures, so if
you don't like this behavior, you must implement your own router or
customize this one.

Thanks,

that's what I was afraid of.
