 Axel,



 Use:
 g_signal_connect (GTK_OBJECT (GTK_FILE_SELECTION (file_selector)->ok_button),
                      "clicked",
                      G_CALLBACK (store_filename),
                      (gpointer)file_selection_widget_goes_here);
 }

 void store_filename (GtkFileSelection *file_selector, gpointer user_data){
  gtkFileSelection fs = GTK_FILESELECTION(user_data);
 ....
 }


Hope this helps.
    That way, you can
