Does anybody know if there is a Qt widget that simulates this effect?
What I want to do is when the user inputs some data and these data are invalid, this bubble appears and tell to user ‘hey, there is an error here!’

Well, I would use a frameless (setting Qt::FramelessWindowHint) QDialog with a custom painting.
