[Paraview] Paraviewweb

[Sebastien Jourdain]

Hi Jane,

keep the prarview mailing list in the loop so anyone could contribute and learn.

In your case that will be pretty simple.
If you use jQuery as JavaScript library that could look like that:

var sourceProxy = paraview.FindSource({name:"Fluid_f2.vtk"});
var representation = paraview.GetDisplayProperties({proxy: sourceProxy});
$('.my-button-class').click(function() {
  if($(this).toggleClass("showLabel").hasClass("showLabel")) {
    representation.setSelectionPointLabelVisibility(1);
  } else {
    representation.setSelectionPointLabelVisibility(0);
  }
});

Or you can create a python script on the server side that can be
called from the JavaScript.
For more details on that you can read the plugin documentation of
ParaViewWeb here.
