[Paraview] linking vtkSMStringVectorProperty to a SLOT

[Nehme Bilal]

Thanks Utkarsh. This will solve the problem.
I have another question:
to get the array from the client, I implemented a method in my server
side that look like this:
void SetArrays(const char *array, int state).
This works perfectly but what if my StringVectorProperty was an
information_only property that I want to set in the server side and
display in the client.
How can I set the element of an information_only StringVectorProperty
that looks like this in the server side: ?
      <StringVectorProperty
         name="Arrays"
         command="GetArrays"
         repeat_command="1"
         number_of_elements_per_command="2"
         element_types="2 0"
         information_only=1>
      </StringVectorProperty>

Thank you,
Nehme
