Hello,

I’m yet again stuck, I apologize for all the questions I’ve been posting recently, but all of the answers have been very helpful, so I’m trying it again :)

I want to register some callbacks to update my UI accordingly. One of them is a global one I was able to register with the help of the documentation: http://www.ephere.com/autodesk/max/docs/902.html. (SystemNotificationCode.SelNodesPostDelete).

Problem 1:

Now I would like to also have a callback for when the stack of my object(s) is getting collapsed. I found:

void NotifyPostCollapse(IINode node, IObject obj, IIDerivedObject derObj, int index);

in ‘IBaseObject’ however I don’t know how to actually register to it? I thought about inheriting IBaseObject, this didn’t really work because then I’d have to implement all the methods from IBaseObject, I tried to inherit from BaseObject but even then I don’t know what to do with my new class…

Problem 2:

I want to register an INodeEvenCallback. I got this so far:

var hmm = new NodeEventTest();

m_Global.INodeEventCallback.CreateUnmanagedWrapper(hmm);

   class NodeEventTest : INodeEventCallback

   {

       public override void GeometryChanged(ITab<UIntPtr> nodes)

       {

           DebugMethods.Log("GeomChanged");

 

           base.GeometryChanged(nodes);

       }

 

       public override void LinkChanged(ITab<UIntPtr> nodes)

       {

           DebugMethods.Log("Link Changed");

           base.LinkChanged(nodes);

       }

 

       public override void LayerChanged(ITab<UIntPtr> nodes)

       {

           DebugMethods.Log("Layer Changed");

           base.LayerChanged(nodes);

       }

   }

This doesn’t work though, am I registering it correctly, with CreateUnmanagedWrapper? I’ve also tried .Create() and .InitializeLifetimeService() without luck.

Thank you in advance!
