Re: [Paraview] points and cells labels
One possible solution is to add the labels as a point data or cell data array of type vtkStringArray and then use the selection labeling mechanism to label with this string array.

Re: [Paraview] points and cells labels
Thanks Utkarsh for your response. that's what I already did. I used empty string on points where I don't want to display properties. But the user must use the selection inspector to see the labels. Is there a way to do the selection from the filter code. It will be perfect if I can select the points I want from inside the filter code, or simply select all points will help also.

Re: [Paraview] points and cells labels
Nehme, Is this in a custom application/python or ParaView GUI. In python/custom-app you can yourself create (representations, DataLabelRepresentation) representation proxy and connect it to the output of your filter. Then it will label all points/cells.

But it most certainly is not recommended. Fetching data from the output of any filter/source should be done only by views such as the render view/xy line plot view/ spreadsheet view etc. However if you insist on getting the data to the client side create a client-delivery representation. Look at the implementation of Fetch() function in Utilities/VTKPythonWrapping/paraview/servermanager.py for details. However I'd still recommend to rethink -- do you really need the full data or just some meta-data that can be obtained from the vtkPVDataInformation associated with the input?

Information properties are properites with information_only=1 set in the XML (eg. in Servers/ServerManager/Resources/rendering.xml the Camera proxy has CameraPositionInfo as an information property). Such properties need an InformationHelper which knows how to obtain the values from the server. For simple Get*() methods, you can use the SimpleDoubleInformationHelper/ or SimpleIntInformationHelper / etc. based on the type of the property. Complex information helpers can be written as well. Look at TimeStepsInformationHelper (vtkSMTimeStepsInformationHelper.h|cxx) as an example. Information objects are used to get data from server which cannot be simply put in a property for example information about the data object produced by a filter (vtkPVDataInformation). These are vtkPVInformation subclasses. You can create you own vtkPVInformation subclass that knows how to collect information and then serialize/deserialize it for transfer to the client from the server (if needed). To gather such information, one uses vtkProcessModule::GatherInformation(vtkIdType connectionID, vtkTypeUInt32 serverFlags, vtkPVInformation* info, vtkClientServerID id) where id is vtkSMProxy::GetID() returned for the proxy from which you want to collect the information. In your case, information property may be an easier solution -- if I understand your problem correctly. There is a pqServerManagerModel instance accessible as pqApplicationCore::instance()-getServerManagerModel() that can be used to access sources/filters their representations, views etc. Take a look at Qt/Core/pqServerManagerModel.h for the API. That should help you access the visualization pipeline. How to get, for instance, the ids of the nodes which are displayed after the application of a filter to the model ? Not sure I understand what you mean by that. Can you please elaborate?

I'm using the svn version of paraview and the parser seems to hang but
it doesn't report an error. I assume that's a bug which will be fixed
pretty soon
