It primarely does the same, that is :

  • add representation for a 2D equalizer widget in a chart view
  • add the Equalizer filter

With some improvements :

  • add vtkSMNewWidgetRepresentationProxyAbstract and pqInteractivePropertyWidgetAbstract to prevent code duplication between 2D and 3D widgets.
  • add ShowInteractiveWidgets and HideInteractiveWidgets python functions in paraview.simple and it's corresponding tracing, as well as deprecating Show3DWidgets and Hide3DWidgets
  • add XML hint WidgetVisibilityLink to allow interactive widget linked to a source with multiple output to only be shown when a specific output port is selected in the Pipeline Browser. The behavior is shown in the following GIF :
