Change background for Widget by StyleSheet, buttons doesn’t show 3D frame.

Code:

---

QWidget {
	background: rgb(8, 8, 8);
}

---

somebody help me!

its because your style sheet also affects the background of your buttons. Is it only one specific widget? If so use th # selector with the object name. Or use ".QWidget".

Thank you!

It works fine. If I use the StackedWidget, the designer doesn't show correct.
