一，先上最终效果图

由于制不来gif就只能传个hover状态的了,所以看不出实际效果了

二，主要代码：

1.头文件

#include<QObject>

#include <QWidget>

#include<QPaintEvent>

#include<QEvent>

#include<QPushButton>

#include<qpropertyanimation.h>

#include<QDebug>

class my360button : public QPushButton

    Q_OBJECT

public:

    my360button(QPixmap pixnormal,QPixmap pixenter,QPixmap pixleave,QWidget*parent);

    ~my360button();

protected:

    void enterEvent(QEvent*);

    void leaveEvent(QEvent*);

    void paintEvent(QPaintEvent*);

    QPropertyAnimation*m_enteranimation;

    QPropertyAnimation*m_leaveanimation;

    QList<QPixmap> m_enterlist;

    QList<QPixmap> m_leavelist;

    QPixmap m_pixnormal;

    int m_enterIndex;

    int m_leaveIndex;

    bool m_enter;

    bool m_leave;

public slots:

    void entervaluechange(QVariant var){m_enterIndex=var.toInt();update();}

    void leavevaluechange(QVariant var){m_leaveIndex=var.toInt();update();qDebug()<<m_leaveIndex;}

};

.cpp文件

#include"my360button.h"

#include<QPainter>

#include<QDebug>

my360button::my360button(QPixmap pixnormal,QPixmap pixenter,QPixmap pixleave,QWidget*parent):QPushButton(parent)

    setCursor(Qt::PointingHandCursor);

    m_leave=false;

    m_enter=true;

    m_leaveIndex=0;

    m_enterIndex=0;

    m_pixnormal=pixnormal;

    for(int i=0;i<10;i++)//进入

        m_enterlist<<pixenter.copy(i*(pixenter.width()/10),0,pixenter.width()/10,pixenter.height());

    for(int j=0;j<8;j++)//离开

        m_leavelist<<pixleave.copy(j*(pixleave.width()/8),0,pixleave.width()/8,pixleave.height());

    m_enteranimation=new QPropertyAnimation(this,"");

    m_enteranimation->setStartValue(0);

    m_enteranimation->setEndValue(9);

    m_enteranimation->setDuration(600);

    connect(m_enteranimation,SIGNAL(valueChanged(QVariant)),this,SLOT(entervaluechange(QVariant)));

    m_leaveanimation=new QPropertyAnimation(this,"");

    m_leaveanimation->setStartValue(0);

    m_leaveanimation->setEndValue(7);

    m_leaveanimation->setDuration(600);

    connect(m_leaveanimation,SIGNAL(valueChanged(QVariant)),this,SLOT(leavevaluechange(QVariant)));

my360button::~my360button()

    delete m_leaveanimation;

    delete m_enteranimation;

void my360button::enterEvent(QEvent *)

    m_enter=true;

    m_leave=false;

    m_enteranimation->start();

void my360button::leaveEvent(QEvent *)

    m_enter=false;

    m_leave=true;

    m_leaveanimation->start();

void my360button::paintEvent(QPaintEvent *)

    QPainter painter(this);

   if(m_enter)

    painter.drawPixmap(rect(),m_enterlist.at(m_enterIndex));

   if(m_leave)

    painter.drawPixmap(rect(),m_leavelist.at(m_leaveIndex));
