关于Qt的动态效果的button

现在我有一份代码，但我不会具体怎么使用。请问Qt大神能给我一个具体使用的例子吗。代码如下：

Button::Button(QWidget *parent) : QPushButton(parent)
{
//保存图片成员初始化
buttonPicture = new QPixmap();
pressPicture = new QPixmap();
releasePicture = new QPixmap();

//关闭按钮的默认显示
this -> setFlat(true);
}

void Button::setButtonPicture(QPixmap pic)
{
*buttonPicture = pic;

this -> setIcon(QIcon(*buttonPicture));
}

void Button::setPressPicture(QPixmap pic)
{
*pressPicture = pic;
}

void Button::setReleasePicture(QPixmap pic)
{
*releasePicture = pic;
}

void Button::set_X_Y_width_height(int x, int y, int width, int height)
{
this -> setIconSize(QSize(width, height));
this -> setGeometry(x, y, width, height);
}

void Button::mouseDoubleClickEvent(QMouseEvent *event)
{
//null
}

void Button::mousePressEvent (QMouseEvent *event)
{
this -> setIcon (QIcon(*pressPicture));
}

void Button::mouseMoveEvent(QMouseEvent *event)
{
//null
}

void Button::mouseReleaseEvent (QMouseEvent *event)
{
this -> setIcon(QIcon(*releasePicture));
emit clicked();
}

一个简单例子：

class Button;
class Widget : public QWidget
{

   Q_OBJECT

public:

   Widget(QWidget *parent = 0);
private:

   Button *botton;
};

//实现方法

Widget::Widget(QWidget *parent)

   : QWidget(parent)
{

   botton = new Button(this);

   botton->set_X_Y_width_height(10,10,80,30); //设置button停靠位置和大小

    //设置button原图片，按下时图片，抬起时图片

   botton->setButtonPicture(QPixmap("d:\\1.png"));

   botton->setPressPicture(QPixmap("d:\\2.png"));

   botton->setReleasePicture(QPixmap("d:\\3.png"));
}

按下时：

抬起时：
