Hi,

> so when the user presses the right mouse button, the menu appears ?

Add a callback for the 'button_press_event' signal of the TreeView
widget, using:

        g_signal_connect (G_OBJECT(treeview),
                "button-press-event",
                G_CALLBACK(popup_menu_cb), NULL);

Where popup_menu_cb is a callback in the form:

gboolean
popup_menu_cb (GtkWidget *widget,
               GdkEventButton *event,
               gpointer user_data);

In order to catch the right click, you must check that event.button
is == 3.

Once you're inside the callback, just create a Gtk::Menu widget, pack
all the Gtk::MenuItems, and show it using gtk_menu_popup().

Hope this helps,
 Emmanuele.
