Plug-in components are CWnd-derived classes that can share a window handle with another CWnd and process window messages for that window. This allows you to implement reusable window functionality that can be attached to various window classes. There is no need to inherit from an existing window class only to add a specific functionality.

CGXPluginComponent is the base class for all plug-in components.
