<div dir="ltr"><div><div><div><div><div>Dear catalyst users,<br></div>I am sorry I cannot document the detailed steps how to set up the catalyst to paraviewweb connection, bescause I am only experimenting how to get it right at the moment. I have received several emails asking for guidance, but I would like to ask you to pose your questions on this mailing list so that others may contribute who have more experience.<br></div>Again, the essential step is happening in pqCatalystConnectReaction::connect(). You don't need any Qt calls, but if you follow that method, you find that a vtkSMLiveInsituManager is created, which can be used for the further client-server communication. I could receive a rendered image from catalyst in the web client, but a real "live" connection is not yet working. I cannot answer questions like "How did you do it", because my setup is a big mess, and I would have to go through all steps again if I wanted to document this mess. If you describe instead what you did and what doesn't work, we may be able to find a solution together.<br><br></div>If you study the contents of pv_web_catalyst.py and Web/Javascript/Widgets/CatalystBrower it seems like all this has already been solved one year ago.<br><br></div>Regards<br></div>Sven<br></div><div class="gmail_extra"><br><div class="gmail_quote">2016-05-23 18:44 GMT+02:00 Sven Kramer <span dir="ltr"><<a href="mailto:svenkramer40@gmail.com" target="_blank">svenkramer40@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div>Sure, I would share the code.

However, you'll probably find a cleaner solution to invoke pqCatalystConnectReaction::connect() from the web client.<span class="HOEnZb"><font color="#888888"><br><br></font></span></div><span class="HOEnZb"><font color="#888888">Sven<br></font></span></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">2016-05-23 7:22 GMT+02:00 Sebastien Jourdain <span dir="ltr"><<a href="mailto:sebastien.jourdain@kitware.com" target="_blank">sebastien.jourdain@kitware.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Glad to ear that you managed to get something going.
