Hi, I use something like this:

/* Set a GtkEntry.
 */
void
set_gentry( GtkWidget *entry, gchar *fmt, ... )
{
        va_list ap;
        gchar *str;

        if( !entry )
                return;

        if( !fmt )
                fmt = "";

        va_start( ap, fmt );
        str = g_strdup_vprintf( fmt, ap );
        va_end( ap );

        gtk_entry_set_text( GTK_ENTRY( entry ), str ); 

	g_free( str );
}

Hope this helps,

John
