QFrame with border-radius inside QGraphicsScene

[DeRatizator]

For some reason QFrame with round border gets drawn with square background in QGraphicsScene.
It appears normally if added to other widgets using layout. Should I do something special in case of QGraphicsScene/QGraphicsView to clip background properly ?

Got the same problem with QPushButton, QWidget in general. Anyone could help?

you can fix this problem by setting attribute of a the widget ( QPushButton , QToolButton or any other widget which can have border-radius ) like this :

QPushButton btn;
btn.setAttribute(Qt::WA_NoSystemBackground,true);
btn.setStyleSheet(".........

Please do not forget that the widget won't have a default background anymore and you need to set the background color in your stylesheet.
