How to resize my .gif file to full screen in any monitor? C++

[Raikoho]

I have created an app that show my gif, but any gifs shows with their own size and i do not know how to resize they to full screen. I use only QLabel, becouse it doesn't show any frame and icons. I need only gif as result. Here my code:

#include <QtGui>
#include <QMainwindow>
#include <QString>
#include <QPixmap>
#include <QtWidgets>
#include <QLabel>
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QLabel* label = new QLabel();
    label->setWindowFlags(Qt::FramelessWindowHint);
    label->setSizePolicy(QSizePolicy::Ignored, QSizePolicy::Ignored);
        label->setScaledContents(true);
        label->setMargin(0);
    label->setMask((new QPixmap("F:\\ADDOBE ANIMATE\\proj\\ulq.gif"))->mask());
 QMovie *movie = new QMovie("F:\\ADDOBE ANIMATE\\proj\\ulq.gif");
 label->setMovie(movie);
 movie->start();
    label->show();
 return a.exec();


}

Can u help me how to resize result to full screen? And is this code a good way to show animations? Sorry for mistakes in English

You still can use a frameless QWidget / QWindow. (setWindowFlags(Qt::FramelessWindowHint)), because then you could do something like:

window.showFullScreen();

(showFullScreen() does not work on QLabel)
