Qt/C++ 360安全卫士主界面动态按钮demo

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));

}
