Hi, @kouba01 thank you so much for another interesting lecture about python for the files handling.

I need assistance here that how you have built this layout of user interface where each section is wrapped in a box and other children are in that box. And there is a frame border for the box and at the bottom a thick border. Please help me to understand it. If you can provide a small tutorial about this layout then it will be great for me to learn more Qt Designer layouts and interface actually it is looking very interesting to me.
