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

[Verhoeven, Nicolaas (UK)]

(errata)
Typo in first message

The constructor is not
myDecorator::pqIrisAnnotationDecorator(pqDisplayPanel* panel) : Superclass(panel)
but
myDecorator:: myDecorator(pqDisplayPanel* panel) : Superclass(panel)

Apologies

I have inherited a plugin for text annotation which is based on the source 'Annotated Time'.
The text plugin is constructed as given by http://www.cmake.org/Wiki/ParaView/Plugin_HowTo#Deprecated

I know the constructor of myDecorator can be used to access the property FontSize e.g.
myDecorator::pqIrisAnnotationDecorator(pqDisplayPanel* panel) : Superclass(panel)
{
  pqRepresentation* rep = panel->getRepresentation();
  vtkSMProxy* repProxy = rep->getProxy();
  vtkSMProperty* smProb = repProxy->GetProperty("FontSize");
  QVariant v = pqSMAdaptor::getElementProperty(smProb);
  int fontSize0 = v.value<int>();
}
Therefor appending the following to this should change the fontsize.

  v.setValue<int>(12);
  pqSMAdaptor::setElementProperty(smProb0,v);

However this does not have any effect.

Questions:
Is it possible to use a 'decorator' to change the default settings as set by rendering.xml
If yes. What do I have to add to achieve my goal?
Further the used methods are flagged as deprecated.
What are the recommended alternatives?
Can these be used to change to default values via a plugin?

Regards

Niek
