• centralWidget containing QWidget
• statusBar
• toolBar

I have menu in main window with action actionAddDock. When that action is triggered there should be addNewDock slot called. That slot calls method addDock(QString title).
But the reason I write is that when I call it first time the tab is not showing (QDockWidget is showing but without tab). Only when there is at least two QDockWidgets the tabs are showing up.

constructor:
@
MyWindow::MyWindow(QWidget *parent)
: QMainWindow(parent)
{
ui.setupUi(this);

setDockConfiguration();
connect(ui.actionAddDock, SIGNAL(triggered(bool)),
  this, SLOT(addNewDock()));

}
@

setDockConfiguration():
@
void MyWindow::setDockConfiguration()
{
setDockOptions(AnimatedDocks | AllowTabbedDocks | ForceTabbedDocks);
setTabPosition(Qt::BottomDockWidgetArea, QTabWidget::North);
setTabShape(QTabWidget::Rounded);
}
@

addNewDock():
@
void MyWindow::addNewDock()
{
addDock("Test");
}
@

addDock(QString title):
@
void MyWindow::addDock(QString title)
{
QDockWidget *newDock = new QDockWidget(title, this);
newDock->setTitleBarWidget(new QWidget());
newDock->setAllowedAreas(Qt::BottomDockWidgetArea);

newDock->setFloating(false);
newDock->setFeatures(QDockWidget::DockWidgetMovable 
/*QDockWidget::DockWidgetClosable |
QDockWidget::DockWidgetFloatable*/);
addDockWidget(Qt::BottomDockWidgetArea, newDock);

// Add docking widget to list QList<QDockWidget*> dockList;
bool isEmpty = dockList.isEmpty();
if(!isEmpty)
{
  int index = dockList.size() - 1;
  tabifyDockWidget(dockList[index], newDock);
}
dockList.append(newDock);

}

Is there any way to show tab when there is only one QDockWidget?
