    I think your callback function needs to have GtkWidget *widget as
    the first passed parameter.
     
    such as:
     
    void text_insert_cb(GtkWidget *buffer, ..., gpointer user_data) 
     
    because the callback function is going to cast it as a basic widget
    when it makes the call.  You may be able to recast it once it's in
    your callback function, but it's not passed as GtkTextBuffer type..

        Hi all 
        i have a small problem 
        
        i have a textbuffer 
        
          contents = gtk_text_view_new (); 
          buffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW (contents)); 
                /* Implementing undo/redo... */ 
        insert = g_signal_connect (GTK_OBJECT (buffer), "insert_text", 
                                GTK_SIGNAL_FUNC (text_insert_cb), NULL);
        
        and the callback 
        void text_insert_cb(GtkTextBuffer *buffer, 
                                                    GtkTextIter pos, 
                                                    const gchar *text, 
                                                    gint length, 
                                                    gpointer user_data) 
        { 
        fprintf(stderr,"%s", text); 
        } 
        
        but it prints some garbage 
        and when i run the program i get: 
        GLib-GObject-WARNING **: invalid cast from `GtkTextBuffer' to
        `GtkObject' 
        
        what's the problem here ? 
        can anyone point me ?? 
        
        Thanks a million
