[Paraview] Highlighting Selected Area

[Rafael March]

Thanks for the reply, Utkarsh !
 
Yeah, that's a possibility ! I'll try to do this way !

But I think what I need is even simpler as changing the active selection: I need only to change only the colors ! I mean, if I had a method vtkCell::setColor(int,int,int), for instance, it would be exactly what I need ! :)
 
Thanks y'all,
Rafael March.

Hey Rafael,

Okay this is a bit advanced (and hacky at the same time -- in ParaView design
object inspector panels are never meant to affect the active selection), but you
can give it a try for your plugin.

In your custom object, when the user changes the 'index' you can set up
a ("sources", "ThresholdSelectionSource") proxy instance
(create a new one if needed) and set it as the selection input to the proxy the
panel is showing (vtkSMSourceProxy::SetSelectionInput). You can look at
pqSelectionInspectorPanel::select to see how the a new selection source may be
created.

I want to do is, when a specific integer is selected, the cells which have this
number associated as scalar data have their edges "highlighted". By
highlighted I mean coloured in green, pink, red, or any different color.
