Substitute of QDesktopWidget

[Jeronimo]

Hi i am trying to show my photos in my program developed in QT. But this example is outdate i'm using QDesktopWidget for qt 5.7. So which is the new class you recommend me? Sorry it's because i want to edit my pictures with QT and take some type of effects.
Code:

imagen1 = new QImage(QApplication::desktop()->width(),QApplication::desktop()->height(),QImage::Format_RGB32);
    imagen1->fill(QColor(0,0,0).rgba());
    sincroniza = 0;

Good bye!

Hi! What do you mean by "outdated"? Looking at http://doc.qt.io/qt-5/qdesktopwidget.html, QDesktopWidget looks okay to me.

@Wieland I was thinking that the class was outdated but not.
