[Paraview] Custom panel widget

[Utkarsh Ayachit]

> Is it possible to create a custom widget for a filter which would allow me to retrieve the results of its computation? I would like to reproduce the functionality of the pqDoubleVectorPropertyWidget and populate it with values computed by the filter. I know how to create and register the widget but I do not know how do I send values to it from the filter. In paraview code base  I found vtkEventQtSlotConnect but I do not know if it is of any use to my problem.

There are several ways of skinning this cat. Can you elaborate of what
exactly is your use-case? Do you want the default values for this
double-vector-property (DVP) set using some values provided by the VTK
filter, but allow user to override using UI?
