[Paraview] custom view plugin - minimal example needed

Fri Jan 26 03:26:31 EST 2018

Hi Kolja

Inheriting directly from vtkPVView is not possible as there is specific
code dedicated to managing each type of base view. Even if it was possible,
it would not allow you to add QtWidget anywhere in the view.
This is not possible due to design.
However, there are possibilities to add Qt widgets in the properties panel,
in the view tool items and in any dedicated QDockWidget or QToolbar you may
want to add in your plugin.

Also please keep in mind this mailing list is a volontary Q&A, We do offer
consulting services [1] if you want to work with ParaView development team
directly.

Best,
