Hi Utkarsh,
The addPropertyLink works exactly as desired and triggers the necessary update
mechanism. For a few places I still have direct connect() to catch the signal
and do something additional with it, but that was expected. I don't know why I
still need an SetImmediateUpdate to get the changes propagated properly, but
that can wait. The most important thing is that I can now load my reader module
in paraview 5.2 and move forward.
Thank you,
/mark

Mark,
As you can expect, connecting Qt widgets to vtkSMProperty's on proxies
in a two-way-link is common in ParaView panels and hence ParaView
provides quite a few ways for doing that. For your use-case, where
you're connecting a QCheckBox to an IntVectorProperty on the proxy,
your pqPropertyWidget subclass can do something like the following:
Assuming your XML for the group is as follows:
QCheckBox *checkbox = ...
vtkSMProperty* smProperty = smgroup->GetProperty("InterpolateFields");
this->addPropertyLink(checkbox, "checked", SIGNAL(toggled(bool), smProperty);
That should do it.
