本文讲解Qt钟表自定义控件实例。

效果如下：

创建钟表类

#ifndef TIMEPIECE_H
#define TIMEPIECE_H

#include <QWidget>
#include <QPropertyAnimation>
#include <QDebug>
#include <QPainter>
#include <QtMath>

#include <QTimer>

#include <QTime>
#define PI 3.14159
#define Div_Max  12 //大刻度值
#define Div_Min  5 //小刻度值
class TimePiece : public QWidget
{
    Q_OBJECT
    //属性系统定义
    Q_PROPERTY(QColor borderColor READ getBorderColor WRITE setBorderColor)
public:
    explicit TimePiece(QWidget *parent = nullptr);
    ~TimePiece();
protected:
    void paintEvent(QPaintEvent *);//重绘

public:
    QColor getBorderColor()const;
    void setBorderColor(const
