[Paraview-developers] How to use the "Parameters" property of "Programmable Filter" in pvpython?

[Di Cheng]

Hi, everyone

I am using Programmable Filter in paraview. I noticed that there is a Parameters property in Programmable Filter. But I cannot use it in GUI, either in pvpython.

I referred the C++ document about this filter in [http://www.paraview.org/ParaView3/Doc/Nightly/www/cxx-doc/classvtkPythonProgrammableFilter.html], It is used to pass arguments to python script. BUT, I CANNOT USE IT in pvpython. I think it is because it accept two or more parameters and cannot be wrapped by XML file.

I know there is a undocumented GetClientSideObject() method which could work in "builtin:" mode. But it could only work locally

Currently, I am using a script generator to pass arguments
-----code-----
def pass_arg_script(d):
"""
generate script to pass parameters in dictionary d={'name':value}
value can be numpy arrays
"""
    s=""
    for k in d:
        s+='self.'+k+'='+repr(d[k])+'\n'
        s+="print '"+k+"=', self."+k+'\n'
    return s

pf.Script = s+ pf.Script
------end of code------

My question is: Is there any decent way to pass Parameters to Programmable Filter in pvpython?
