Alignment of layout doesn't work

bergungsdackel

Hello.

I tried to create some buttons and labels in a layout (no matter which layout - vbox, hbox, gridlayout) but it doesn't align. Its position is everytime in the top left corner and I can't change it...

Code from mainwindow.cpp

    QGridLayout *gLayout = new QGridLayout(this);

    QLabel *headText = new QLabel(this);
    headText->setText("Welcome to your point'n'click adventure");
    QPushButton *startButton = new QPushButton("&Start game",this);

    gLayout->setAlignment(Qt::AlignCenter);
    gLayout->addWidget(headText,0,0,Qt::AlignCenter);
    gLayout->addWidget(startButton,1,0,Qt::AlignCenter);

    this->setLayout(gLayout);

Hi and welcome to devnet,

What version of Qt ?
On what OS ?
What is MainWindow ?
Please provide a complete minimal compilable example that reproduce the behaviour so that people can test.

On a side note, QGridLayout *gLayout = new QGridLayout(this); already applies the layout on the widget represented by this therefore this->setLayout(gLayout); is redundant. If MainWindow is a QMainWindow, then you can't apply a layout on it because it already has one that provides all the bells and whistles of that class.
