[Glade-users] get_widget out of GtkBuilder xml file in C-Code

[msp430]

hello friends of GLADE,
        
        how do i get a pointer to a widget built with glade, which is
        called by
        the generated GtkBuilder xml file "statusbar1"!?
        
         builder = gtk_builder_new ();
         gtk_builder_add_from_file (builder, "myproject.glade", NULL);
        
         i tried several things like this:
        
        GtkWidget* statusbar;
        
        statusbar = glade_xml_get_widget(builder, "statusbar1");
        and other things. but nothing worked for me.
        
        error message i get:
        implicit declaration of function ‘glade_xml_get_widget’
        
        i know this is not the GladeXML type
        builder is GtkBuilder type.
        
        Is there a way to get the widget from the GtkBuilder xml file,
        to show / hide this widget by the following method or another
        one?
        
         gtk_widget_hide(statusbar);
         gtk_widget_show(statusbar);
        
        thanks a lot 
        i really was looking for this 2 days now.
        
        greetings
