格式化输入日期时间控件
可以用jieformatteddatebox box = new jieformatteddatebox("yyyy年mm月dd日hh点mm分ss秒");输入
也可以用jieformatteddatebox box = new jieformatteddatebox("hh:mm:ss");来输入时间
还可以这样用jspinner spinner = new jspinner();jieformatteddatebox fdb = new jieformatteddatebox(format);spinner.setmodel(fdb);spinner.seteditor(fdb);
