Hand cursor display zone

GoDiagram (6 and previous)
1

On a CollapsingRecordNode (CRN), the cursor changes to a hand when the mouse hovers close to the boundaries, indicating that the CRN can be linked to other GoNodes from there…

I am looking for a way to make the zone that triggers the cursor change wider as it is sometimes very difficult to position the mouse at the exact position to fire the event, especially on zoomed-out diagram.

Thanks in advance for any hints on how to accomplish this!

In CollapsingRecordNodeItem:

    // don't need the top and bottom ports, so don't create them!
    protected override GoPort CreatePort(int spot) {
      if (spot == GoObject.TopCenter || spot == GoObject.BottomCenter)
        return null;
      GoPort p = base.CreatePort(spot);
      p.Size = new SizeF(8, 8);         // Add this line, the sample uses 4, 4 (the GoTextNode default)
      p.AutoRescales = false;
      return p;
    }
