Align text on center

[Roberrt]

How i could stop the Loading text from moving to the left, but still continue aligned to the center of the button?

auto timer = new QTimer();
auto button = new QPushButton(this);

button->setGeometry(50, 50, 200, 50);
QGridLayout* layout = new QGridLayout();
button->setLayout(layout);

QLabel* label = new QLabel(button);
label->setStyleSheet("qproperty-alignment: AlignCenter;");

layout->addWidget(label);

timer->setInterval(500);
timer->start();

QObject::connect(timer, &QTimer::timeout, [=]
{
    static int dot = 0;

    dot = (dot + 1) % 4;

    QString text = "Loading...";
    text.resize(7 + dot);

    label->setText(text);
});

static int dot = 0;

   dot = (dot + 1) % 4;

   QString text = QString("Loading%1").arg("",dot,'.');
   text=QString("%1%2").arg(text).arg("",10-text.size(),' ');

   label->setText(text);

Not the best I guess ;)
anyway can't work correctly because, space and point have not the same size on not fixed font.

Would be better to use a fixed left margin for the label.
