Layout.Arrange only arranges top-level nodes. Try this method to also arrange containers' contents:

The router should pull links apart automatically if you call RouteAllLinks method, instead of link.Route called from a loop as shown in the linked post. So try replacing the foreach loop in Arrange with a call to diagram.RouteAllLinks().

I hope that helps,

There is something I'm missing - I'm an idiot
Please ignore that last question.

The problem was that the DiagramView doesn't contain a Diagram until it has been activated, so I wasn't hooking up the the Diagram to insert my graph elements.

I have pretty much everything working that I need now, except zooming...

I am trying to use the DiagramView::SetZoomFactor to zoom around the current mouse position.  I am unsure what units the pivot point is in.

I have tried the following in the MouseWheel event:
GetPosition(<view>)
<view>.TransformToDocument(point)
<View>.SetZoomFactor(zoom,transformedPoint);

but that doesn't zoom centred around the mouse.

What do I need to do?

Thanks,

Jim.

OK, ClientToDoc works better than TransformToDocument, but it still doesn't feel like the zooming is around the mouse position.  It kind of starts off around the mouse but as I zoom in, the section of the diagram I want to look at starts to slide out of view.

Thanks,

Jim.

Hmmm, yes your example does work.
I am doing the same thing in my code and it doesn't work.

I have found that if I change to using:

e.GetPosition(diagram.DocumentPlane)

and don't do any transform then I can get it to work as expected.

Since I've got zooming to work as I want, then that takes care of all my current issues.

Thanks for all your help.

Jim.
