I want to make a custom app with PyQt5 ( GPL and commercial license) or Pyside2 ( LGPL), that uses ParaView Framework. But I’m having problem with the license. Do I have to pay to use it? How much?

What license are you asking about? ParaView’s license requires no fee for use. For PyQt5, you would have to ask the folks that own it.

Hi Gon,

I’m trying to do the same but my problem is the paraview results always opens in a separate window. Can you please help me with coding or share your code if it’s possible?
