How to display Widgets in the midle of a Window

**revellix** · 24th July 2011, 20:25

Following problem:

I want to display a widget in the middle of a QMdiSubWindow. I also want to use Tabs later. Therefore I add a QStackWidget to a QMdiSubWindow. The first QStackWidget is a Widget I constructed called inAOrifice. Now in the Fullscreenmode the inAOrifice Widget isnt that big and I want to display it in the middle of the QMdiSubWindow, in the QStackWidget respectively. It always appears in the left upper corner. Any suggestions? I have tried a lot already. Cant see my mistakeâ€¦

Most common code yet â€¦

Qt Code:

Switch view

MainChild::MainChild(QWidget *parent) : QMdiSubWindow(parent)
{
    this->setAttribute(Qt::WA_DeleteOnClose);
 
    inAOrifice = new inputAOrifice(this);
    stackLayout = new QVBoxLayout(this);
    stackWidget = new QStackedWidget;
 
    stackWidget->addWidget(inAOrifice);
    stackLayout->setAlignment(stackWidget,Qt::AlignCenter);
    this->setWidget(stackWidget);
 
}

MainChild::MainChild(QWidget *parent) : QMdiSubWindow(parent)
{
    this->setAttribute(Qt::WA_DeleteOnClose);

    inAOrifice = new inputAOrifice(this);
    stackLayout = new QVBoxLayout(this);
    stackWidget = new QStackedWidget;

    stackWidget->addWidget(inAOrifice);
    stackLayout->setAlignment(stackWidget,Qt::AlignCenter);
    this->setWidget(stackWidget);

}
