[Paraview-developers] How do you modifying the text display panel default settings via a plugin?

[Sebastien Jourdain]

Hi Niek,

If you try to automatically change any text representation that get created
to use some other font size default, the right way to do that is to almost
do the same thing as the example that you can find in ParaView source tree
under the following directory: Examples/Plugins/RepresentationBehavior

But the content of the onRepresentationAdded will look like that:

void pqSurfaceRepresentationBehavior::onRepresentationAdded(pqRepresentation*
rep)

{

  if(rep->getSMName() == "TextSourceRepresentation")

    {

    vtkSMPropertyHelper(rep->getProxy(), "FontSize").Set(12);

    rep->getProxy()->UpdateVTKObjects();

    }

}


Seb
