[Paraview-developers] Selecting blocks from drop down list

[Jorge Bañuls]

Hi Andy,

Indeed, the vtkExtractBlock filter is what I'm using in my script to
extract the blocks, which are currently specified by the user in the
properties panel as a string with the name of the block(s). Now that you
mention it though, it could be useful to see how this filter creates the
checklist. Is there a way to access the code behind this filter?

Thanks a lot for your help,

Jorge Bañuls
