Qt QGraphicsView和StyleSheets

Question

Can I use CSS/stylesheets to style a item in QGraphicsView, like QGraphicsWidget? If yes, how?

Answer 1

I don't think it's directly possible, at least if you apply a stylesheet to the QGraphicsView itself it will not affect any widgets inside of it. However, you can assign a stylesheet to a widget before adding it into the scene, then it will keep it's style after being added:

QGraphicsScene scene;
QPushButton b;

b.setStyleSheet("QPushButton{background-color:red}");
scene.addWidget(&b);

QGraphicsView view(&scene);
view.show();
