Hi folks,
I have a problem in adding a NPointPort to a NCustomShape. The NCustomShape is in a library browser.
Always if I drop (a copy of) the master in the drawing document, the port is on position 0,0 of the drawing document and not in the shape bounds.
In the following code I create the custom shape with one port (to the fourth point):
private NCompositeShape createComplexCompositeShape()
{
NCompositeShape shape = new NCompositeShape()
NPolygonPath newElement = new NPolygonPath(new NPointF[]
{
new NPointF(0, 10),
new NPointF(0, 90),
new NPointF(50, 90),
new NPointF(50, 100),
new NPointF(50,90),
new NPointF(100, 90),
new NPointF(100, 10),
new NPointF(50, 10),
new NPointF(50, 0),
new NPointF(50,10),
});
shape.Primitives.AddChild(newElement);
shape.UpdateModelBounds();
shape.Style.FillStyle = new NColorFillStyle(Color.AliceBlue);
shape.Style.StrokeStyle = new NStrokeStyle(1, Color.FromArgb(0, 0, 0x88));
// create the shape ports
shape.CreateShapeElements(ShapeElementsMask.Ports);
NPointPort port1 = new NPointPort(shape.UniqueId, PointIndexMode.Custom, 4);
shape.Ports.AddChild(port1);
return shape;
}
Any tips?
Kind Regards
Wilhelm

Hi Wilhelm,
The problem with the port positioning is the anchor model that you pass to the NPointPoint constructor. A composite shape does not implement the INPoints interface and that is why the point port cannot position itself correctly - it will always return (0,0) as its scene coordinates. To fix the problem just replace:
NPointPort port1 = new NPointPort(shape.UniqueId, PointIndexMode.Custom, 4);
with
NPointPort port1 = new NPointPort(newElement.UniqueId, PointIndexMode.Custom, 4);

Hi Nevron support,
thank you for the good tip. It works now.
