如何将 GIF 设置为 QToolButton

问题描述 投票:0回答:2

我想在

"GIF"
上显示
QToolButton
图像。

目前,我将

QMovie
设置为
QLabel
,并通过隐藏
QLabel
显示
QToolButton

我也尝试过使用样式表设置 GIF,但失败了。

是否可以直接在

QToolButton
上显示动画图像(.gif)?

#include <QtGui>
#include <QToolButton>

class TOOTBtn : public QToolButton
{
    Q_OBJECT
public:
    TOOTBtn(const QString &imgPath, const QString &label, QWidget *parent = 0)
        : QToolButton(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"
#include <QApplication>
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("a.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();
}

QMovie*fan_gif=new QMovie("://png/gif/fan.gif");
QSize MovSize(48, 48);
fan_gif->setScaledSize(MovSize);
QLabel*pLabel = new QLabel(ui->toolButton_fan_1);
pLabel->setMovie(fan_gif);
fan_gif->start();
pLabel->setGeometry(5, 5, 48, 48);
