Hi all,

I'm trying to create an instance of NTreeLayout as follows

Dim treeLayout As New NTreeLayout(document)

but I'm getting this error

'New' cannot be used on a class that is declared 'MustInherit'

now then, looking at the user guide, it should be possible to create an instance that way...
What I'm doing wrong?

User Guide - Tree Layout

Thank you all for your responses.

Thank you for your answer, you may want to update the documentation then...

User Guide - NTreeLayout

The tree layout is used to automatically arrange graphs, which represent tree structures. The tree layout algorithms are encapsulated inside the NTreeLayout class (derived from NLayout), which can be instanced on demand:

' create a new tree layout associated with the specified document 
Dim treeLayout As New NTreeLayout(document)

Hi,

This topic is not part of the official Nevron .NET Vision documentation. Here's a link to a topic about a specific tree layout:

Layered Tree Layout

As you can see on the navigation on the left, there isn't a link to this old topic, you are referencing. Only the file of this topic has left. Most probably we forgot to delete it from the server. Thank you very much for reporting that. We will delete it from the server soon, so that there isn't any confusion.

Best Regards,
Nevron Support Team
