[Paraview] custom view plugin - minimal example needed

Tue Jan 23 13:55:02 EST 2018

Thanks, Mathieu, unfortunately the RenderView or the other hardcoded views
won't work for us.
As I described, I need to implement a custom view with a bunch of input
fields and buttons to represent data statistics.

The corresponding Qt views of the 4 mentioned View classes are created in
pqStandardServerManagerModelInterface::CreatePQView using hardcoded tests
such as:
 if (xmlname == pqSpreadSheetView::spreadsheetViewType())
  {
    return new pqSpreadSheetView(group, name, proxy, server, parent);
  }
Is it feasible to create another, generic vtkPVView-derived class besides
vtkPVRenderView...vtkSpreadSheetView, which will allow to define the view
elements using the plugin mechanism?

We can add menus, buttons and toolbars through plugins, why not customize a
generic view? Is there a reason that forbids such customization, or is it
just one of those topics that hasn't received sufficient interest or
funding, but could be implemented in principle?
Thanks
Kolja
