Super introduction to Qt objects. Qt sounds amazing coming from a c# background. I love the idea of composition capability being inherited to all objects; what a smart design choice; no more having to create custom properties to achieve this for it is built right in. I can't wait to get started. It sounds so flexibly. Thanks for introducing me to this. Great Job!

Very good video. I would however mention that you do not need to set parents for widgets in constructor for widgets which are inside layouts. The parent is set automatically when widget is put into layout.

Great first video in your playlist, I'm going to go through the entire set if this is how you teach.

I do have one concern with your code though. Is there a memory leak issue introduced due to the way that QHBoxLayout and QVBoxLayout was created in the code? Shouldn't they both be parented to the "window" QWidget?
