Stoyan,

Has the polyline been made available as line type for Layered Layout yet?

If not, when do you think this can be made available?

Thank you.

LayeredLayout.LinkType = Straight sets the links Style to Polyline and inserts a control point for each layer the link passes through. Do you need something different than this?

Thank you but I am not able to get the result that you've described. I will send you an e-mail shortly with an attachment.

Thank you

You could insert an additional point at each end of the link to implement that:

Code
Select All
private void miLayoutLayered_Click(object sender, EventArgs e)
{
	LayeredLayout ll = new LayeredLayout();
	ll.Orientation = MindFusion.Diagramming.Layout.Orientation.Horizontal;
	ll.Arrange(diagram);

	foreach (DiagramLink link in diagram.Links)
	{
		PointCollection p = link.ControlPoints;

		PointF sp = p[0];
		p.Insert(1, new PointF(sp.X + 5, sp.Y));

		PointF ep = p[p.Count - 1];
		p.Insert(p.Count - 1, new PointF(ep.X - 5, ep.Y));

		link.UpdateFromPoints(false, true);
	}
}


I hope that helps,
Stoyan

Thank you. I was wondering if there was a way to set all lines to have exactly two points (three segment) specifically while minimizing total distance and overlap with a node. The first and last segment would be horizontal.

Thank you for your help.

You need to shift the nodes in such a way that links that pass across more than one layer do not bend?

I think it mainly has to do with how the lines are drawn.
Let is what I am getting now and right is what I am trying to get to.

As you may notice, the line in the example have three segments (at most) that goes across the layers if necessary.

It might be possible; could you email the saved xml for that diagram to support@mindfusion.eu, along with your layout code?

We have added a StraightenLongLinks property that will let you get a similar layout. You can find the updated version on the PM page. Now the file you sent us is laid out as shown below:

Code
Select All
private void miLayoutLayered_Click(object sender, EventArgs e)
{
	LayeredLayout ll = new LayeredLayout();
	ll.Orientation = MindFusion.Diagramming.Layout.Orientation.Horizontal;
	ll.EnforceLinkFlow = true;
	ll.StraightenLongLinks = true;
	ll.NodeDistance *= 7;
	ll.LayerDistance *= 3;
	ll.Arrange(diagram);
}




Currently it ignores the node sizes; we'll implement that in the next few days, along with better centering of short links.

Now StraightenLongLinks supports nodes of different size and finds better positions for closer nodes. You can find the new build on the PM page.

Stoyo,

Thank you very much for this. I have tested the property on the back-end but I am running an applet and in this case

ll.setStraightenLongLinks(true);

doesn't seem to work. Is this the correct syntax?

Thank you again.

We haven't implemented this in the Java applet yet.

Stoyan,

Thank you for the confirmation. Do you know how soon this would be implemented in Java Applet?

Thank you.

Stoyan,

I was wondering if you had any estimate when this new feature would be available in Java Applet.

Thank you,

James

We won't have a Java developer available to implement this at least for a couple of weeks.
