[tingsking18]

论坛里发言就"要" 的真不少啊.....
为有发扬QT,这个小demo,拿去吧.....

#include <QtGui>

class TOOTBtn : public QPushButton
{
    Q_OBJECT
public:
    TOOTBtn(const QString &imgPath, const QString &label, QWidget *parent = 0 )
        : QPushButton(label,parent)
    {
        if(!imgPath.isEmpty()){
        _movie = new QMovie(imgPath, QByteArray(), this);
        connect(_movie, SIGNAL(frameChanged(int)), this, SLOT(iconChged(int)));
        _movie->start();
       }

        setIconSize(QSize(64,64));
    }

private slots:
    void iconChged(int){
        setIcon( _movie->currentPixmap());
    }

private:
    QMovie *_movie;

};


#include "main.moc"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QWidget window;
    TOOTBtn btn("zoe.gif", "Test Btn....", &window);
    btn.move(100,100);
    window.show( );
    window.resize(640,400);
    window.setWindowTitle("TOOTzoe.com Animating Button Test....");
    QObject::connect(&btn, SIGNAL(clicked()), &window, SLOT(close()));

    return app.exec();
}

#include "main.moc"

包含moc文件，如此之怪？

[Aisy_D]

用 QMoive 或者 paintevent + timer....

如果设置为按钮背景动画该怎么样做.?

[Aisy_D]

#include <QtGui>

class TOOTBtn : public QPushButton
{
    Q_OBJECT
public:
    TOOTBtn(const QString &imgPath, const QString &label, QWidget *parent = 0 )
        : QPushButton(parent), _label(label)
    {
        if(!imgPath.isEmpty()){
        _movie = new QMovie(imgPath, QByteArray(), this);
        connect(_movie, SIGNAL(frameChanged(int)), this, SLOT(iconChged(int)));
        _movie->start();
       }

    }

private slots:
    void iconChged(int){

        QTextDocument Text;
        Text.setHtml(_label);

        QPixmap currFrame = _movie->currentPixmap();
        QPixmap pixmap(Text.size().width(), currFrame.height());
        pixmap.fill( Qt::transparent );
        QPainter painter( &pixmap );
        painter.drawPixmap(( pixmap.width()-currFrame.width()) / 2  ,
                           ( pixmap.height()-currFrame.height()) / 2, currFrame );
        Text.drawContents(&painter, pixmap.rect());

        setIcon(QIcon( pixmap));
        setIconSize(pixmap.rect().size());
    }

private:
    QMovie *_movie;
    QString _label;

};


#include "main.moc"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QWidget window;
    QString TOOTLabel = QObject::tr("<h2><i>Hello</i> <font color=red>TOOTzoe.com</font></h2>"
                                    "<b>Animating Button Test....<b>");
    TOOTBtn btn("zoe.gif", TOOTLabel, &window);
    btn.move(100,100);
    window.show( );
    window.resize(640,400);
    window.setWindowTitle("Animating Button Test....");
    QObject::connect(&btn, SIGNAL(clicked()), &window, SLOT(close()));

    return app.exec();
}

还有更高级的效果, 不便相告.....
