I am creating a new QHBoxLayout and adding two widgets to this layout. I want them to be beside each other and in the center like the image below.

Currently, they are aligned horizontally but with a lot of space.

    auto layout= new QHBoxLayout(this);
    layout->addWidget(button1, 0, Qt::AlignmentFlag::AlignCenter);
    layout->addWidget(button2, 0, Qt::AlignmentFlag::AlignCenter);
