    connect(timer, &QTimer::timeout, this, &MainWindow::SetValueProgress);

}

MainWindow::~MainWindow()

    delete ui;
}

void MainWindow::on_pushButton_clicked()

    QMovie *movie=new QMovie("/home/adx-soft1/Desktop/Sankarapandiyan/loadinggif/loadingimage.gif");
    if (!movie->isValid())
    {
        // Something went wrong :(
    }
    // Play GIF
    //QLabel  * label = new QLabel();

    label=new QLabel();
    label->setGeometry(115,60,128,128);
    label->setMovie(movie);
    label->show();
    movie->start();
}
void MainWindow::SetValueProgress()
{
    //label->hide();
}

@sankarapandiyan said in Gif is not displayed while clicking the Push button.-----> Loading GIF Operation is not works properly:

movie->isValid()

what does it return?

Hi
To avoid managing the timer we could use
QTimerSingle shot.

    QMovie *movie = new QMovie(":/somegif.gif");
    if (!movie->isValid()) {
        // Something went wrong :(
        return;
    }
    // Play GIF
    auto label = new QLabel(); // no this as we want it as a window
    //label->setGeometry(115,60,128,128); This moves it to top corner of screen...
    label->resize(128, 128);
    label->setMovie(movie);
    label->show();
    movie->start();
    // start time to close it after 10 secs
    QTimer::singleShot(10000, [label] {
        label->close();
        label->deleteLater();
    });
