It might be easiest to reimplement QWidget::paintEvent() and simply stretch/center the image by hand.

void MyWindow::paintEvent(QPaintEvent* event)
{
    static QPixmap bg(":/button/Resources/1.bmp");
 
    QPainter painter(this);
    // streched:
    painter.drawPixmap(rect(), bg, bg.rect());
    // or centered:
    // painter.drawPixmap((width() - bg.width()) / 2, (height() - bg.height()) / 2, bg);
}

void MyWindow::paintEvent(QPaintEvent* event)
{
    static QPixmap bg(":/button/Resources/1.bmp");

    QPainter painter(this);
    // streched:
    painter.drawPixmap(rect(), bg, bg.rect());
    // or centered:
    // painter.drawPixmap((width() - bg.width()) / 2, (height() - bg.height()) / 2, bg);
}
