How to insert an animated picture (GIF) in a QLabel

[AngiSad]

I have been trying to insert an animated picture GIF in a QLabel. I searched in Google to see how to do it (I am a newbie )
I used this code:

#include <QtGui>
 
int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QLabel w;
 
    // On crée une vidéo. Ici, c'est un GIF
    QMovie movie("c:/Mickey-11.gif");
    // On l'associe à un label
    w.setMovie (&movie);
    // On lance la vidéo
    movie.start ();
 
    w.show();
    return app.exec();
}

#include <QtGui>
 
int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QLabel w;
 
    // On crée une vidéo. Ici, c'est un GIF
    QMovie movie("c:/Mickey-11.gif");
    // On l'associe à un label
    w.setMovie (&movie);
    // On lance la vidéo
    movie.start ();
 
    w.show();
    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

(from http://qt.developpez.com/faq/?page=animation#gif_anime)

but it is not working. They mentioned compiling the GIF plugin but I didn't know how to do it.

Thanx for your help
