QPainter. How to draw a number + Animation?

Question

Qt

How to draw a number (let's say 1) in QPainter and animate the change from 1 to 10 on button click?

Answer 1

Try to read the documentation and ask Google about examples of using QPainter, read any book on Qt. It's not a question, it's a "do the lab for me" task.
