Tabify 3 QDockWidget

Question

How to create a tabbed dock for 3 widgets in QMainWindow?

I am using the following code:

widget1 = new QDockWidget(this); widget1 ->setObjectName("name1"); addDockWidget(Qt::LeftDockWidgetArea, widget1); widget2 = new QDockWidget(this); widget2 ->setObjectName("name2"); addDockWidget(Qt::LeftDockWidgetArea, widget2); tabifyDockWidget(widget2, widget1); widget3 = new QDockWidget(this); widget3->setObjectName("name3"); addDockWidget(Qt::LeftDockWidgetArea, widget3); tabifyDockWidget(widget3, widget1); 

This code leads to two docks: only dock-2 and docking stations 1 and 3.

To fix, I simply reposition the first and second parameters:

 widget1 = new QDockWidget(this); widget1 ->setObjectName("name1"); addDockWidget(Qt::LeftDockWidgetArea, widget1); widget2 = new QDockWidget(this); widget2 ->setObjectName("name2"); addDockWidget(Qt::LeftDockWidgetArea, widget2); tabifyDockWidget(widget2, widget1); widget3 = new QDockWidget(this); widget3->setObjectName("name3"); addDockWidget(Qt::LeftDockWidgetArea, widget3); tabifyDockWidget(widget1, widget3);
