Qt封装QPropertyAnimation动画基类，所有界面通用实现界面类似手机滑动切换_qparallelanimationgroup 页面平滑切换

简单粗暴，直接上代码：
#include “Cbaseanimation.h”

#ifndef CBASEANIMATION_H
#define CBASEANIMATION_H
#include <QObject>
#include <QPropertyAnimation>
#include <QParallelAnimationGroup>
#include <QtWidgets/QWidget>

#include <QTimer>
// 界面动画基类
class CBaseAnimation : public QObject
{
    Q_OBJECT
public:
    CBaseAnimation();
    ~CBaseAnimation();

    void SetAnimation(QWidget *curwidget, QWidget *destwidget,bool directon);
//    void SetAnimation(QWidget *widget,int Duration,bool directon);

//    void SetTimeOutReturn(bool enable,uint mse = 0);


//    bool GetTimeOutReturnEnable();
private:

    QLabel * pixmapLabel;
    bool isAnimationFinish;
//    QWidgetList widgetlist;
//    QTimer * m_timer;
//    bool isTimeOutReturnEnable;
signals:
