How do I use the zValue to display items on the scene?

[anda_skoa]

Hi guys, I have four QGraphicsItems that are stacked one on top of the other using the zValue. Each QGraphicsItem is the same size as the scene rect, so I can only display one item at a time.

Why bother with z value if only one if visible at any given time?

void MainWindow::on_nextBtn_clicked()
{
    if(pageIterator <= 3){
        pagesList.at(pageIterator)->hide();
        pageIterator++;
        pagesList.at(pageIterator)->show();
    }
}

void MainWindow::on_nextBtn_clicked()
{
    if(pageIterator <= 3){
        pagesList.at(pageIterator)->hide();
        pageIterator++;
        pagesList.at(pageIterator)->show();
    }
}

You said you had four pages. This code is allowing access to 5 entries in pagesList.

Cheers,
