about selfloop

Is it not possible to specify the start and end points of the self-loop?

Currently, when a self-loop is created, it is automatically created at the top of the node.

Also, the LinkShape is changed from Cascading to Bezier.

You can specify them from SetSelfLoopShape event handler -

Code
Select All
void OnSetSelfLoopShape(object sender, LinkShapeEventArgs e)
{
	e.Handled = true;

	var link = e.Link;
	var r = link.Origin.Bounds;
	link.Shape = LinkShape.Cascading;

	var points = link.ControlPoints;
	points.Clear();
	points.Add(new PointF(r.X + 5, r.Y));
	points.Add(new PointF(r.X + 5, r.Y - 5));
	points.Add(new PointF(r.X - 5, r.Y - 5));
	points.Add(new PointF(r.X - 5, r.Y + 5));
	points.Add(new PointF(r.X, r.Y + 5));
	link.UpdateFromPoints();
}

Thank you for your response.

When OnSetSelfLoopShape is reached, the ControlPoints of the Link is set to the Bezier value.

Is it possible to get the ControlPoints when the mouse is released?

Sorry.

e.Handled = true

The above was missing.

I was able to achieve what I wanted.

In a self-transition, a link will pass through a node if it is implemented with the following properties.
Is it possible to make it go around the outside of the target node?
--Proterty
RouteLinks: True
LinkShape: Cascading

The sample code above places points around the node, have you left only the Handled assignment from it? AutoRoute does not apply to self-loops, so you'd just see the link as drawn by user if you don't assign to ControlPoints from that handler. If you want to specify only end points without other coordinates, you can still call the Route method:

Code
Select All
void OnSetSelfLoopShape(object sender, LinkShapeEventArgs e)
{
	e.Handled = true;

	var link = e.Link;
	var p = link.StartPoint = e.Link.Origin.Bounds.Location;
	link.StartPoint = new PointF(p.X + 10, p.Y);
	link.EndPoint = new PointF(p.X + 20, p.Y);
	link.Route();
}

I was able to implement it based on your answer.
