Qt实现动态雷达扫描图

话不多说，先看效果图

在看代码

CRadarAnimation.h

#ifndef CRADARANIMATION_H
#define CRADARANIMATION_H

#include <QObject>
#include <QQuickPaintedItem>
#include <QTimer>
#include <QPainter>

class CRadarAnimation : public QQuickPaintedItem
{
    Q_OBJECT
public:
    CRadarAnimation();
    virtual ~CRadarAnimation();

protected slots:

    virtual void paint( QPainter *painter ) override;

    void onTimerTimeout();


private:
    QRectF maxInsideSquareRect();
    void drawCircle( QPainter *painter );
    void drawOutLineCircle( QPainter *painter, const double diameter );
    void drawPie( QPainter *painter );

private:
    // int m_1kmPixels =
    QTimer   m_timer;
    uint16_t m_rotateCount = 0;
};

#endif // CRADARANIMATION
