left/right positioning in a scroolArea

EL-jos

greetings to everyone,
I have a problem that I can't solve alone after several tests, here is my problem: I want that when i will be an even number the positioning of the widget i is to the right if not to the left but with my code it doesn't work, here it is:

for(int i = 0; i < 15; ++i){

        WidgetTest *widget = new WidgetTest(ui->scrollAreaWidgetContents);

        int pair = i % 2;
        if(pair = 0){

            ui->scrollAreaWidgetContents->layout()->setAlignment(ui->scrollAreaWidgetContents->layout(),Qt::AlignRight);
            ui->scrollAreaWidgetContents->layout()->addWidget(widget);
        }else{

            ui->scrollAreaWidgetContents->layout()->setAlignment(ui->scrollAreaWidgetContents->layout(),Qt::AlignLeft);
            ui->scrollAreaWidgetContents->layout()->addWidget(widget);
        }
    }

note it is in a QScrollArea that I want to add the widgets

thank you in advance for your help

Well i used a QGridLayout and simply placed them where needed.
Im not sure bool setAlignment(QWidget *w, Qt::Alignment alignment) will work as we want
but i didnt test it.

        gridLayout = new QGridLayout(scrollAreaWidgetContents);

        frame = new QFrame(scrollAreaWidgetContents);
        gridLayout->addWidget(frame, 0, 0, 1, 1);

        frame_7 = new QFrame(scrollAreaWidgetContents);
        gridLayout->addWidget(frame_7, 1, 2, 1, 1);

@mrjj Thank you very much for your help, but will it be possible to do it in a loop?
since in my case I will create several widgets in a loop and I actually want some to be on the left and others on the right

Hi
Sure it is.

QFrame *MainWindow::MakeFrame( )
{
    QFrame *frame = new QFrame(ui->scrollAreaWidgetContents);
    frame->setFrameShape(QFrame::Box);
    frame->setFrameShadow(QFrame::Raised);
    frame->setMinimumSize(QSize(64, 64)); // make it min size so it dont get too small
    return frame;
}

void MainWindow::on_pushButton_2_released()
{
    for (int cc = 0; cc < 12; ++cc) {
        QFrame *frame = MakeFrame();
        ui->gridLayout->addWidget(frame, cc, cc % 2, 1, 1);
    }
}
