Description
Provides the default implementation class for the DockManager property of container controls.
When you set the UseDockManager property of a container control to True, it uses the value of its DockManager property to manage docking operations. If the application does not explicitly assign a value to DockManager, the control generates a dock manager by instantiating the class specified by DefaultDockTreeClass.
The Controls unit sets DefaultDockTreeClass to TDockTree. Change this value to provide a different default implementation of the dock manager that container controls use when the DockManager property is not explicitly assigned. The class specified by DefaultDockTreeClass must be a descendant of TDockTree.
