[Paraview] linking vtkSMStringVectorProperty to a SLOT

[Utkarsh Ayachit]

There;s no direct way around this. You can handle it in use Qt code by
using a singleshot timer and calling some other slot only on idle.
Alternatively try to look at the code that's modifying the "Array"
property. Instead of using the SetElement() API, change it to using
the SetElements() API which modifies all elements and then fires the
modified event.
