Qt程序设计-钟表自定义控件实例

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
