#include <gtk/gtk.h> struct GtkData;
The GtkData object is a very simple object intended to be used as a base class for objects which contain data (i.e. the 'Model' in the object-oriented Model/View/Controller framework).
Currently it is not very useful since all it provides is a "disconnect" signal. This signal could be emitted by a GtkData subclass to notify any 'Views' that they should disconnect from the GtkData (the 'Model'), possibly just before the GtkData is destroyed.
The GtkData struct contains no public fields.
