get_widget_long_name
string get_widget_long_name(GtkWidget widget); 
    
     Returns the long name of a widget which has been loaded from 
     a glade file.
    
    
     If the widget has been created the "normal" way and not
     with glade, NULL is returned.
    
    
     In the example you could use a
     
var_dump( libglade::get_widget_long_name( $btnClose));
  | 
     which would return string(24) "dlgHellow.vbox1.btnClose".
