[Paraview] Location widgets properties

[Nehmé Bilal]

Hello,

I have a plugin that use location widgets to manipulate points position.
To create the widgets, I use vtkSMNewWidgetRepresentationProxy.
I am able to manipulate the points position correctly, but I would
like to manipulate some other properties of these widgets specially
colors.
Anyone know how can I change the color of vtkSMNewWidgetRepresentationProxy ?

Thank you
