Unsolved How to move/drag widgets between multiple Dockwidgets?

[Sriu1]

I have created a container from this link https://wiki.qt.io/Widget-moveable-and-resizeable
Below is the code where I'm setting this container object to Dockwidget.

QDockWidget *dock = new QDockWidget(tr("D1"), this);
QLabel *GUI_qlabel1 = new QLabel ("Zone 1");
TContainer *container1 = new TContainer (this, QPoint (10, 10), GUI_qlabel1);
container1->setGeometry(100,100,75,75);
dock->setWidget(container1);

I want to create multiple QDockwidgets which should support below requirements
1.The container should be restricted within a dockwidget window.
2.The container should be able to move from one dockwidget window to another(only for a special case).

Please suggest If QDockwidget is the right class for this requirement or should I use any other class.
