Hello,

Try creating a custom Behavior class and return an instance of your arrow class from the StartDraw method. Assign the behavior object to flowhchart.CustomBehavior.

Below you can see how the CreateArrowBehavior class is implemented, change it so it creates new YourArrowClass instances instead of new Arrow instances:

[code]
public override InteractionState StartDraw(PointF pt)
{
  ChartObject ac = fc.ActiveObject;
  Node obj = fc.GetNodeAt(pt);
  int handle = 0;

  if (ac != null && !ac.notInteractive() && ac.pointInHandle(pt, ref handle))
  {
    return new InteractionState(ac, handle, Action.Modify);
  }
  else
  if (obj != null && obj.canHaveArrows(true))
  {
    return new InteractionState(
new Arrow(fc, obj), -1, Action.Create);
  }
  else
  if (obj == null && fc.AllowUnconnectedArrows)
  {
    return new InteractionState(
new Arrow(fc, fc.Dummy), -1, Action.Create);
  }
  else
  {
  return new InteractionState(
fc.Selection, -1, Action.Create);
  }
}
