a GoPort

Remarks

IsValidFrom and IsValidTo are true, by default, thus allowing users to draw links from or to these nodes. You may want to set those properties to false if you want prevent users from drawing links with a mouse-down and drag from the port, or to create a port with a different size or appearance.

Example

If you override this method, you may want the definition to do some of the things that the standard definition does:

protected virtual GoPort CreatePort() {
  GoPort p = new GoPort();
  p.Style = GoPortStyle.None;
  p.Size = new SizeF(6, 6);
  p.FromSpot = NoSpot;
  p.ToSpot = NoSpot;
  p.PortObject = this;
  return p;
}
