Hi,

You can add data to GtkObjects by using gtk_object_set_data (or *_add_data...). It requires you to add a piece of data with a name (or use gtk_object_set_user_data).

Well, if you want to extract data from widgets, just add the widget as data to (for example) the window (or its parent). If you want the widget again, use gtk_object_get_data (). That's the way GLADE does it...

You can do the same trick with your own data structure of course.

Arjan
