[Paraview-developers] Handling exceptions from within a Plug-in

[Ellon Paiva]

Hello Mathieu,

Thanks for your answer.

I think I was not clear in my question. Surely I can catch the exception 
in the plugin, but I'm looking for a way to inform paraview that an 
error occurred while executing the filter. Of course this information 
should be passed to ParaView when handling the exception, and probably 
it should halt the processing of the pipeline as well.

I'm looking now into the files of some plugins inside paraview source. I 
found that some plugins use the macro "vtkErrorMacro". Would this work 
for me?

Regards,

Ellon
