[Paraview] PV4.1, Custom Dock Widget: How to automatically add a glyph3d filter after loading data ?

Wed Sep 17 08:29:33 EDT 2014

Click on the "?" button on the ParaView UI with the filter active.
That'll take you a page that will list all such "properties" available
on the filter. Additionally, you can look at these xml files[1].
Locate the proxy using the group/name and then you'll have the details
for properties on it.
