hi, information keys are more for passing info between filters through
the pipeline. if all you want is to display a string, you could make a
second output port to your reader that produces a vtkTable and populate
it with the string. This could be displayed in the pv ui. here's a quick
example of what you'd do in your request data:
315 vtkInformation *outInfo;
316 vtkTable *output;
317 vtkStringArray *data;
318
319 // output port 1 -> bw data
320 outInfo=outputVector->GetInformationObject(0);
321 output
322 =
dynamic_cast<vtkTable*>(outInfo->Get(vtkDataObject::DATA_OBJECT()));
323 data=vtkStringArray::New();
324 data->SetName("BW Data");
325 data->SetNumberOfComponents(1);
326 data->InsertNextValue(bwData.c_str());
327 output->AddColumn(data);
328 data->Delete();

Hello,
I am trying to get meta-data information from a file into ParaView. I
have successfully built the information key-value pairs in the
information object in my reader, but I am uncertain how to get the
data out on the ParaView side of things.
Example:
I want to get the Calendar date meta-data from my model file. I added
Key to the information object to the results info object.
I set keys as follows:
request->AppendUnique(vtkExecutive::KEYS_TO_COPY(),
vtkENLILMetaDataKeys::REFDATE_CAL());
I have a function to add the value to the key like such:
void vtkENLILMetaDataKeys::populate_meta_data(vtkInformation* request,
vtkInformationStringKey *key, char* value)
{
request->Set(key, value);
}
I then add the values to the keys as follows:
vtkENLILMetaDataKeys::populate_meta_data(outInfo,
vtkENLILMetaDataKeys::REFDATE_CAL(), temp);
After I do this, I can successfully pull the placed data from the
information object from within the reader.
What I cannot figure out is how to access this object from within
Paraview.
My goal is to be able to include the calendar date (as text) in the
render view.
Can someone guide me in the correct direction on how to do this? I am
looking for possibly a python way of getting at this data.
Thanks,
Josh
