Arcs between connections [message #143129] Sun, 18 July 2004 21:49

Hello,

I am working on a project that involves two or more connections
originating from a single connection anchor. I need to draw an arc
between these connections such that the arc is anchored a short distance
below the origin of the two most distant connections.

I am currently doing this by extending the Draw2d PolylineConnection
class' paint method. For a given connection I set (using absolute
coordinates) the termination point of the arc and then use the
Graphics.drawArc method to produce the arc.

My problem is that when using a ScalableFreeformRootEditPart with a zoom
manager zooming the diagram causes the arcs to disappear. Are there any
special considerations that need to be made when using absolute
coordinates on a scalable canvas? Or are there other more appropriate
mechanisms for adding arcs between connections?

Thank you,

Bill Glenn
