Supported image format for QMovie?

[cookie1909]

I have a simple tutorial with QMovie to display an animated gif image. I download the gif file from this link http://www.gifs.net/Animation11/Anim...d_dog_face.gif.

However calling movie->isValid() always returns false for me. What are the supported file types for QMovie? I thought animated GIF was one of them.

Thanks in advance for your help.

#include <QtGui/QApplication>
#include<QWidget>
#include<QHBoxLayout>
#include<QLabel>
#include<QMovie>
#include<QPushButton>
#include<QSlider>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QWidget *win=new QWidget();
    QHBoxLayout *lay=new QHBoxLayout();
    QPushButton *play=new QPushButton("PLAY");
    QPushButton *stop=new QPushButton("STOP");
    QSlider *slider=new QSlider();
    slider->setMinimum(0);
    slider->setMaximum(200);
    QLabel *label=new QLabel;
    QMovie *movie = new QMovie("anim03.gif");
    if (movie->isValid())
        label->setMovie(movie);
    else
        label->setText("asdfasdf");
    QObject::connect(play,SIGNAL(clicked()),movie,SLOT(start()));
    QObject::connect(stop,SIGNAL(clicked()),movie,SLOT(stop()));
    QObject::connect(slider,SIGNAL(valueChanged(int)),movie,SLOT(setSpeed(int)));
    lay->addWidget(label);
    lay->addWidget(play);
    lay->addWidget(stop);
    lay->addWidget(slider);
    win->setLayout(lay);
    win->show();
    return a.exec();
}

    slider->setMaximum(200);
    QLabel *label=new QLabel;
    QMovie *movie = new QMovie("anim03.gif");
    if (movie->isValid())
        label->setMovie(movie);
    else
        label->setText("asdfasdf");
    QObject::connect(play,SIGNAL(clicked()),movie,SLOT(start()));
    QObject::connect(stop,SIGNAL(clicked()),movie,SLOT(stop()));
    QObject::connect(slider,SIGNAL(valueChanged(int)),movie,SLOT(setSpeed(int)));
    lay->addWidget(label);
    lay->addWidget(play);
    lay->addWidget(stop);
    lay->addWidget(slider);
    win->setLayout(lay);
    win->show();
    return a.exec();
}

To copy to clipboard, switch view to plain text mode

you can get supported formats by calling QMovie::supportedFormats.
btw, I can't load that image even in browser.
