如何在Qt中绘制“ x”？

Question

To draw an ellipse in Qt, we can simply go QGraphicsScene->addEllipse();

Is there an equivalent method to draw an 'x'? And when redrawing a scene, how would you delete said 'x' (say, to move it)?

Answer 1

使用QGraphicsScene :: addSimpleText（const QString＆text，const QFont＆font = QFont（））绘制字母“ x”。
