在JCalendar中禁用过去的日期和从现在起2周 [英] Disable past dates and 2 weeks from now in JCalendar

问题描述

我想从JCalendar禁用过去的日期和从现在起2周.

I want to disable past dates and 2 weeks from now from a JCalendar.

我已经有了以下代码:

jDateChooser1.getJCalendar().setMinSelectableDate(new Date());
((JTextFieldDateEditor)jDateChooser1.getDateEditor()).setEditable(false);

我已经可以禁用过去的日期，但是如何禁用从现在起2周之类的将来的日期呢?

I already can disable past dates but how about disabling future dates like 2 weeks from now?

推荐答案

如此处所示，您可以使用IDateEvaluator(例如MinMaxDateEvaluator)会使日期范围无效:

As shown here, you can use an IDateEvaluator like MinMaxDateEvaluator to invalidate a range of dates:

private static class RangeEvaluator extends MinMaxDateEvaluator {

    @Override
    public boolean isInvalid(Date date) {
        return !super.isInvalid(date);
    }
}

然后，您可以指定一系列无效日期，例如前一天和后两个星期:

Then you can specify a range of invalid dates, e.g. a day before and two weeks after:

    Calendar min = Calendar.getInstance();
    min.add(Calendar.DAY_OF_MONTH, -1);
    Calendar max = Calendar.getInstance();
    max.add(Calendar.DAY_OF_MONTH, 13);
    RangeEvaluator re = new RangeEvaluator();
    re.setMinSelectableDate(min.getTime());
    re.setMaxSelectableDate(max.getTime());
    JCalendar jc = new JCalendar();
    jc.getDayChooser().addDateEvaluator(re);
    jc.setCalendar(jc.getCalendar());

请注意，您可以添加RangeEvaluator的多个实例以处理不同的范围.

Note that you can add multiple instances of RangeEvaluator to handle different ranges.
