How to animate layouts in Qt?

Question

Qt

Good day. I'm trying to animate the addition / extraction of objects from layout-a, and other than writing my own control, I didn’t find any better options.
Is there a way to implement this without writing a widget?

Qt Animation?

Answer 2

Writing your successor to some widget in Qt is quick and easy, it's hard to come up with something better. And for animation use QPropertyAnimation.
