[Glade-users] Libglade Tutorial

[Reginald Johnson]

Can somebody point me to a good libglade tutorial.  I'm specifically
looking for the "proper" way to lookup widgets in a callback function. 
for example my "main" function looks like this:

/* Created by Anjuta version 1.2.1 */
/*	This file will not be overwritten */

#ifdef HAVE_CONFIG_H
#  include <config.h>
#endif

#include <gnome.h>
#include <glade/glade.h>
#include "callbacks.h"

int main (int argc, char *argv[])
{
	GtkWidget *window1;
	GladeXML *xml;

	#ifdef ENABLE_NLS
		bindtextdomain (GETTEXT_PACKAGE, PACKAGE_LOCALE_DIR);
		textdomain (PACKAGE);
	#endif

	gnome_init (PACKAGE, VERSION, argc, argv);
	glade_gnome_init ();
	/*
	 * The .glade filename should be on the next line.
	 */
	xml = glade_xml_new (PACKAGE_SOURCE_DIR"/LibGladeMusic2.glade", NULL,
NULL);

	/* This is important */
	glade_xml_signal_autoconnect (xml);
				
	window1 = glade_xml_get_widget (xml, "window1");
	gtk_widget_show (window1);

	gtk_main ();
	return 0;
}

The callback exists in a separate fill called callbacks.c and looks like
this:

void on_butStoreMusic_clicked               (GtkButton       *button,
                                        	gpointer         user_data)
{
	GtkWidget *widget;
	//GladeXML *xml;
	g_print("button clicked\n");
	//xml = glade_xml_new (PACKAGE_SOURCE_DIR"/LibGladeMusicbox.glade",
NULL, NULL);
	widget=glade_xml_get_widget(GladeXML(button), "butStoreMusic");
	//set up the song listing
	//StoreMusicListSetup(button);
	//gtk_notebook_set_page(GTK_NOTEBOOK(widget), 2);

} 

The callback is called because I get the "button clicked" message in the
terminal window, but I can't for the life of me grab a widget so that I
can turn a page in the notebook that the widget exists in.  
I've looked for a good libglade tutorial, but have been unable to find
one so far.
