The central widget is the main content area of a QMainWindow. A QDockWidget is an optional, possibly stackable, possibly undockable, widget that can be placed inside a QMainWindow adjacent to the top, right, bottom or left of the central widget.

Qt has a wide range of examples:

Including one specifically addressing dock widgets,

There is also a large amount of documentation.
