set_label of GtkFrame

I'm using glade2 to make the interface with an GtkFrame. But if I try to change the label, the GtkFrame then looses the label. This is the code: $this->frame_codigo=$this->xml->get_widget('frame_codigo'); $this->frame_codigo->set_label($this->Fcodigo); But if I create a GtkFrame without using glade2 "$frame=new GtkFrame()" and later I try to change the label then it works. So I guess the set_label of the GtkFrame does not work only when the widget is made with glade2. Thanks for the attention. -- []'s Eduardo RBS http://linuxstok.sourceforge.net
