[Paraview] Replacement for colorByArray

[Reuter, Michael A.]

Hi,

I have an application that I’m trying to conform back to git-master in preparation for the version 4.2 release. In the application, I used the pqPipelineRepresentation::colorByArray function to preset the colormap array before the data is rendered. I see that this function has been removed. I did a bit of digging and tried to use the following as a replacement (signal is our default array name):

pqDataRepresentation *drep = objectBuilder->createDataRepresentation(…);
vtkSMPropertyHelper(drep->getProxy(), “Representation”).Set(“Surface”);
vtkSMPropertyHelper(drep->getProxy(), “ColorArrayName”).Set(“signal”);
drep->getProxy()->UpdateVTKObjects();

However, this doesn’t seem to set the correct array as the view shows Solid Color for the array when it renders. I’m either invoking things incorrectly or at the wrong time, but I don’t know what. What am I missing or is there a more appropriate alternative to this method?

Thanks,
M
