Gdk::DragSurfaceImpl is a Gdk::Surface that implements the Gdk::DragSurface interface.
The GdkDragSurface interface can be implemented by C classes that derive from GdkSurface. No public GTK class implements GdkDragSurface. Some GTK functions, such as gdk_drag_get_drag_surface(), return an object of a class which is derived from GdkSurface and implements GdkDragSurface. Since that C class is not public, it's not wrapped in a C++ class. A C object of such a class can be wrapped in a Gdk::DragSurfaceImpl object. Gdk::DragSurfaceImpl does not directly correspond to any GTK class.
This class is intended only for wrapping C objects returned from GTK functions.
