TDockManager is an abstract class for managing a dock site's docked controls.
The declaration contains a number of procedure definitions that are 'virtual' and 'abstract'. This means that there is no implementation specified: these essentially represent 'place-holders', and it is the responsibility of the developer of descendant classes to override these methods and implement them as desired.
