Here are four possibilities:
1. Use global variables for your widgets.
2. Create a struct containing pointers to all your widgets and use the
userdata field to pass this struct around in all callbacks.
3. Use the g_object_set_data() method to attach miscellaneous pointers
to your widgets. I.e. in the widget construction do:
GtkWidget *w_tree_view, *w_button;
w_tree_view = gtk_tree_view_new(...);
:
w_button = gtk_button_new();
g_object_set_data(G_OBJECT(w_button), "tree_view", w_tree_view);
g_signal_connect(G_OBJECT(w_button), "clicked",
G_CALLBACK(cb_button_clicked), NULL);
and in the callback cb_button_clicked() do:
GtkWidget *w_tree_view =
GTK_WIDGET(g_object_get_data(G_OBJECT(widget), "tree_view"));
This method is similar to what glade is doing.
4. Create your own container widget, e.g. by gob2 and put all your
widgets in it. This is a fancy way of doing the struct callback I
mentioned above.
Hope this helps.
