Re: [gtk-list] text-entry retrieval

You would need to give us some more information really.

Yes, it does. It copies the contents of your variable into the entry
internal
variable "gchar *text".

What are you trying to do. Something like this should surely work.
  GtkEntry *field[30];
  ari[30];
--->create the Entries
  for(i=0; i<30; i++)
     gtk_signal_connect(GTK_OBJECT(field[i]), "changed",
                        GTK_SIGNAL_FUNC(read_out_cb), &vari[i]);

---> and the callback function does something like
   read_out_cb(GtkWidget *w, gpointer *data)
   {
   VariableType *var = (VariableType *)data;
   gchar *text;

   text = gtk_entry_get_text(w);

   *var = parse_out_text_to_variable(text);
   }
