cwgraph3d and events

[Toni2]

Hello!

I work with CwGraph3D an LabView. I like to have an event when the cursor on graph changed the position. Is possible to do this?

Thank for a help!

Hello Toni2,

What control exactly are you using? Can you post your example VI with the graph control?

Regards,

Sebastian

A "CwGraph3D " is a Component Works 3D graph.

You can find an LV example that uses the CW 3D graph in this thread.

The CW 3D graph ships with LV and if not written by NI, the rights to it are NI's.

Toni2,

I don't think you can register for a cursor move event. I suspect you will have to poll but I'll leave that for the NI Experts to settle.

Weird - I just experienced what I thought was deja vu when I thought I remembered the same thread you started before about this control.  Turns out you DID start a thread, but a different aspect of the same control.  

I need a nap.

What if you use ActiveX Register Event Callback? I have found that you could register for event CursorChange (attachment screenshot).

It was late yesterday so I have modified the CWGraph3D example in a way that it uses the mentioned callback VI. I have saved it in LabVIEW 2009 so let me know if you would like to have it in earlier version.

I can run the program, but i'dont now how to see the event in case of cursor changed. Can you add this part of code to?

Best regards!

Well, what I did, I put system beep into Callback VI (attached). That's why I know that the callback is working.
