JCalendar问题（2月份）

问题描述

我有一个图形组件用于选择日期。当地日期是6月30日时，问题（或错误）仍然存在;例如，当我经历二月份时，我会用箭头浏览月份，日期会自动插入（2月28日），因为事件propertyChange会启动，除非我选择。

I have a graphical component JCalendar for choosing the date. A problem (or bug) persists when my local date is June 30; for example, I go through the months with the arrow when I go through the month of February, the date is inserted automatically (February 28) because the event "propertyChange" is starts unless I select.

你怎么看？

推荐答案

假设和 JSpinnerDateEditor ，我发现6月30日或2月28日附近没有 JCalendarDemo 。您可以验证您是否正在观察正确的属性更改：

Assuming JCalendar and JSpinnerDateEditor, I see no discontinuities near June 30 or February 28 in JCalendarDemo. You might verify that you are observing the correct property change:

    JDateChooser spinner = new JDateChooser(new JSpinnerDateEditor());
    spinner.addPropertyChangeListener(new PropertyChangeListener() {
        @Override
        public void propertyChange(PropertyChangeEvent e) {
            System.out.println(e.getPropertyName()
                + ": " + e.getNewValue());
        }
    });
    this.add(spinner);

附录：我无法重现你描述的效果，因为它是一个已修复的错误。

Addendum: I am unable to reproduce the effect you describe because it's a bug that's fixed here.

附录：该错误也已修复，版本1.4。

Addendum: The bug is also fixed in JCalendar, version 1.4.
