Arrange QDockWidgets in QMainWindow in multiple columns

I have a class which inherits from QMainWindow. In the constructor, I set the Central Widget to NULL and then add several QDockWidgets to make a user interface which consits of QDockWidgets only: 

UserWidget::UserWidget(QWidget * parent) : QMainWindow(parent)
{
    this->setCentralWidget(NULL);
    // create Widgets for User communication e.g. PushButtons etc.
    // ...
    dockWidget_ = new QDockWidget;
    dockWidget->setAllowedAreas(Qt::AllDockWidgetAreas);
    dockWidget->setWidget(userWidget_);
    this->addDockWidget(Qt::RightDockWidgetArea);

Now I add another QDockWidget but instead of Qt::RightDockWidgetArea, I choose Qt::LeftDockWidgetArea: 

    dockWidget_ = new QDockWidget;
    dockWidget->setAllowedAreas(Qt::AllDockWidgetAreas);
    dockWidget->setWidget(userWidget2_);
    this->addDockWidget(Qt::LeftDockWidgetArea);

Up to here, the appearance of my program is similar to this:

enter image description here

Proceeding further with adding another QDockWidget: 

    dockWidget_ = new QDockWidget;
    dockWidget->setAllowedAreas(Qt::AllDockWidgetAreas);
    dockWidget->setWidget(userWidget3_);
    this->addDockWidget(Qt::LeftDockWidgetArea /* or Qt::RightDockWidgetArea*/);

I end up with one of the area splitted in the middle :

enter image description here

But I want to split the layout into 3 columns, similar to:

enter image description here

However, I did not find any suitable way to do this. Setting the area to Qt::TopDockWidgetArea or Qt::BottomDockWidgetArea neither provides the desired behavior. I would really appreciate any help here.

You just have to use the function splitDockWidget() :

void QMainWindow::splitDockWidget(QDockWidget *first, QDockWidget *second, Qt::Orientation orientation)

In your case, you can put one QDockWidget (let's call him dock1) on the left and the other two on the right (dock2 and dock3) and the call the function like this : 

splitDockWidget(dock2, dock3, Qt::Horizontal);
