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);
