qtcharts 星座图

要在Qt中绘制星座图，你可以使用Qt的绘图类和图形界面工具。下面是一个简单的示例代码，演示如何使用Qt绘制星座图：

#include <QApplication>
#include <QPainter>
#include <QPointF>

void drawConstellation(QPainter* painter)
{
    // 例如，这里是一些星座坐标的示例数据
    QPointF star1(50, 50);
    QPointF star2(100, 100);
    QPointF star3(150, 50);
    QPointF star4(200, 100);

    // 设置画笔和画刷
    painter->setPen(Qt::blue);
    painter->setBrush(Qt::yellow);

    // 绘制星座连线
    painter->drawLine(star1, star2);
    painter->drawLine(star2, star3);
    painter->drawLine(star3, star4);

    // 绘制星座点
    painter->drawEllipse(star1, 5, 5);
    painter->drawEllipse(star2, 5, 5);
    painter->drawEllipse(star3, 5, 5);
    painter->drawEllipse(star4, 5, 5);
}
