I would like to write my own XPresso result node, adding further data "types" to the list. Is there a documented way to do this?

Is there any XPresso node plugin code available?

Thanks!

Hi Kabe

How are you? The class GvOperatorData should do that for you.

Override the methods and register this class to get your own node.
Here is an example:
*click*

Search keyword: GvOperatorData

In the SDK you find an example to create custom datatypes - take a look

Bye...

Also don't forget to check the description files (gvresult.res, gvresult.h, gvresult.str) for the node's interface description.
