这个程序就是使用lunar-calendar控件，然后显示出农历来。

先用glade-2画出一个日历窗口，设置窗口的销毁事件为调用gtk_main_quit函数，设置一下窗口图标，然后生成代码

设计后的glade-2的界面代码

</glade-interface>

生成的源代码文件有：

src/callbacks.c
callbacks.h
interface.c
interface.h
src/main.c
src/Makefile.am
support.c
support.h

support.c/.h文件中就是一些支撑函数，一般不用管

我们需要关注就是interface.c/.h，这个文件就是创建控件的函数。

按照lunar-calendar说明，将interface.c中调用gtk_calendar_new替换成lunar_calendar_new，同时增加lunar-calendar/lunar-calendar.h的包含

修改完后的源代码如下：

生成并修改后的interface.c文件

GtkWidget*create_lunarcalendar (void)

{

  GtkWidget*lunarcalendar;

  GdkPixbuf*lunarcalendar_icon_pixbuf;

  GtkWidget*calendar1;



  lunarcalendar=gtk_window_new (GTK_WINDOW_TOPLEVEL);

  gtk_widget_set_name (lunarcalendar,"lunarcalendar");

  gtk_window_set_title (GTK_WINDOW (lunarcalendar), _("Lunar Calendar"));

  lunarcalendar_icon_pixbuf= create_pixbuf ("lunarcalendar.png");if(lunarcalendar_icon_pixbuf)

    {

      gtk_window_set_icon (GTK_WINDOW (lunarcalendar), lunarcalendar_icon_pixbuf);

      gdk_pixbuf_unref (lunarcalendar_icon_pixbuf);

    }



  calendar1=lunar_calendar_new ();

  gtk_widget_set_name (calendar1,"calendar1");

  gtk_widget_show (calendar1);

  gtk_container_add (GTK_CONTAINER (lunarcalendar), calendar1);

  gtk_calendar_display_options (GTK_CALENDAR (calendar1),

                                GTK_CALENDAR_SHOW_HEADING|GTK_CALENDAR_SHOW_DAY_NAMES|GTK_CALENDAR_NO_MONTH_CHANGE|GTK_CALENDAR_SHOW_WEEK_NUMBERS);



  g_signal_connect ((gpointer) lunarcalendar,"destroy",

                    G_CALLBACK (gtk_main_quit),

                    NULL);/*Store pointers to all widgets, for use by lookup_widget().*/GLADE_HOOKUP_OBJECT_NO_REF (lunarcalendar, lunarcalendar,"lunarcalendar");

  GLADE_HOOKUP_OBJECT (lunarcalendar, calendar1,"calendar1");returnlunarcalendar;

}

到此，我们完成了第一步，生成代码
