    I am developing Accounting Software for which I want to use QT Textline, and Label, like widgets, Can I use LGPL Licence? I will sell the Accounting Software Under the Brand name to the end user.
    I will not modify the qt code, I will use PySide 6 in python

      @Sunil-Pandya Yes, you can use LGPL license for commercial products as long as you link dynamically (no static LGPL libraries). You have to provide your users the possibility to replace Qt or any other LGPL libraries with their own versions.
      Keep in mind: I'm not a lawyer!

        In addition to @jsulm, don't forget that if you sell/distribute your code you are required to provide a means for your users to download the full source code of Qt, without just pointing to TQtC web site. Probably meaning you need to put it somewhere on your web site. Just so you are aware.
