Hello!

I know that vtkClientServer.cxx wraps up some functions.

I use this knowledge to pass some data from the filter to the widgets which support this filter, for user to get more information about the filter

How can I pass a vtkIntArray via it? The function is generated in vtkClientServer.cxx file, but vtkIntArray is unknown… Seems like functions returning this kind of values are not wrapped up

Thanks

What is the signature of the method you’re trying to have wrapped?
