How to make an additional form a tab of the main form and back?

Question

Qt

Actually an example would be Photoshop.
There, child windows with images can be dragged onto the main form, and they become its tabs, and vice versa, if you drag the tab, it becomes a separate window.
Modern browsers, Google chrome for example, can also be an example.
How to implement this in QT? Are there any examples, or at least in which direction you need to dig?
