java编写的带界面的日历程序。可以点击某一个时间

/****************************************************************************************
*							Java日历程序

*    作者：张亚航
*
*    完成时间：2008-5-22
*
*	 程序功能：
*	 使用Swing组件编写界面，能够正确显示月历，并且拥有四个按钮分别进行显示控制
*		
*    设计思路：
*    本程序总体使用MVC设计模式，其中viewer包中的CalWin程序是主界面显示程序，
*    主要用于界面的生成和数据的刷新；
*    
*    Model包中的MyDate类是程序日历的载体，本程序没有使用JDK的类库java.util.Date和
*    java.util.Calendar类，而是重新构造了MyDate类，该类只能保存精度到日的时间
*    
*    Control包中的ComputeDate类主要是用来计算每个月的第一天是星期几以及每个月的总天数
*    
*    Viewer类中包含了一个内部类Cell，Cell是界面日期表格中显示中的基本元素，继承与JLabel
*    ，每个Cell对应一个MyDate对象。
*    
*    程序主要流程是根据当前baseDate利用ComputeDate计算当前月份的数据，然后将所有数据
*    通过setCell方法同Cell[]数组关联起来，初始化所有Cell，然后将数据在界面显示。
*    每次日期发生改变，都要调用一次setCell方法，将所有界面数据刷新。
*
