如题，各位大佬，如何在圆环外再设置一个动态的椭圆，这个椭圆自动随着这个圆转动。。。
- void RingWidget::paintEvent(QPaintEvent *event)
- {
- Q_UNUSED(event);
- QPainter painter(this);
- painter.setRenderHint(QPainter::Antialiasing);
- QRadialGradient gradient(0, 0, height()/2);
- gradient.setColorAt(0, qRgb(3,139, 153));
- gradient.setColorAt(1.0, qRgb(169, 238, 125));
- painter.setBrush(gradient);
- int m_persent = 90;//绘制的环的比例
- int m_rotateAngle = 360*m_persent/100;
- int side = qMin(width(), height());
- QRectF ouRect(0, 0, side, side);//矩形长宽为窗口的长宽d
- QRectF inRect(20, 20, side-40, side-40);
- //画外圆
- painter.setPen(Qt::NoPen);
- //p.setBrush(QBrush(QColor(97, 117, 118)));
- painter.drawEllipse(ouRect);
- //画内圆
- //p.setBrush(QBrush(QColor(255, 107, 107)));
- painter.drawPie(ouRect, (90-m_rotateAngle)*16, m_rotateAngle*16);
- //画遮罩，遮罩颜色为窗口颜色
- painter.setBrush(palette().window().color());
- painter.drawEllipse(inRect);
- //画文字
- QFont f = QFont("Microsoft YaHei", 15, QFont::Bold);
- painter.setFont(f);
- painter.setPen(Qt::white);
- painter.drawText(inRect, Qt::AlignCenter, m_strDescribe);
- }
如上，以上是我绘制圆环的代码，怎么再这个圆环外再加一个动态的椭圆，这个椭圆的边框会自动围绕圆环进行转动。各位大佬，劳烦大家指点一下，小弟在此多谢了！
