Hi,
I would like to add ports to a NComposite but it seems that the method "CreateShapeElements" doesn't
work? When I try to use the "HeatExChanger1.Ports.ChildrenCount(null))" it gives 0??
That means that it fails to use the line.startplug.connect and line.endplug.connect methods. What should I do instead?
protected NCompositeShape CreateHeatExchanger(NPointF location, float scale)
{
NCompositeShape HeatExchanger = new NCompositeShape();
GraphicsPath graphicsPath = new GraphicsPath();
graphicsPath.StartFigure();
PointF[] points = new PointF[]
{
new PointF(175,140),
new PointF(175,160),
new PointF(150,170),
new PointF(200,170),
new PointF(175,180),
new PointF(175,200),
}; graphicsPath.AddLines(points); NPointF[] points2 = new NPointF[]
{
new NPointF(145,140),
new NPointF(205,140),
new NPointF(205,200),
new NPointF(145,200),
}; NPolygonPath exterior = new NPolygonPath(points2); HeatExchanger.Primitives.AddChild(new NCustomPath(graphicsPath, PathType.OpenFigure));
HeatExchanger.Primitives.AddChild(exterior);
HeatExchanger.Style.FillStyle = new NColorFillStyle(Color.Empty); HeatExchanger.UpdateModelBounds(); HeatExchanger.CreateShapeElements(ShapeElementsMask.Ports);
HeatExchanger.Location = location;
HeatExchanger.Width = HeatExchanger.Width * scale;
HeatExchanger.Height = HeatExchanger.Height * scale;
return HeatExchanger;
}
