Re: gtk_combo_box_get_active_text fails ???

[Antonio Gomes <tonikitoo gmail com>]

Hi Olivier,

first, you must to be care with the requered prototype of each signal
. In the case of changed in a gtk_combo_box context, the prototype of
the callback associated with this signal must be as following:

Signal Prototypes

"changed"   void        user_function      (GtkComboBox *widget,
                                            gpointer user_data);

so , try to correct it and the callback signiture to

void select(GtkComboBox *combo, gpointer unused) {...}

tell us, if it does not make any effect !

best regards
