GWT DateBox-禁用特定日期

问题描述：

我想在日期框中禁用特定日期。我使用此代码尝试了此操作，但是指定的日期（当日）没有被禁用。

I want to disable a specific date in my date box. I tried it with this code, but the specified date (current day) does not get disabled.

final DateBox dateBox = new DateBox();
dateBox.getDatePicker().addShowRangeHandler(new ShowRangeHandler<Date>() {

    @Override
    public void onShowRange(final ShowRangeEvent<Date> event) {
        List<Date> disabledDates = new ArrayList<Date>();
        disabledDates.add(new Date());
        dateBox.getDatePicker().setTransientEnabledOnDates(false, disabledDates);
    }
});

还有其他方法吗？

编辑：按照apanizo的示例，当天29.5看起来是灰色的，但是仍然可以单击。

Following the example of apanizo, the day 29.5 looks greyed out, but is clickable nevertheless.

答

真的很抱歉，我没有测试我的最后一个答案的代码。

Really sorry, I did not test the code of my last answer.

我刚刚尝试了并且您的代码对我有效，我唯一要做的就是通过所有通过 setTransientEnabledOnDates（false，dateToDisable）; 方法不需要的日期。

I have just tried and your code worked to me, the only thing that I did was pass all the dates that I do not want through the setTransientEnabledOnDates(false, dateToDisable); method.

示例：

public void onModuleLoad() {
    final DateBox dateBox = new DateBox();

    dateBox.getDatePicker().addShowRangeHandler(new ShowRangeHandler<Date>() {
        @Override
        public void onShowRange(final ShowRangeEvent<Date> dateShowRangeEvent) {
            final Date today = new Date(); //30 May 3014
            final Date yesterday = new Date(today.getTime()- 24*60*60*1000);

            //disabling yesterday - 29 May of 2014
            dateBox.getDatePicker().setTransientEnabledOnDates(false, yesterday);

        }
    });

    RootPanel.get().add(dateBox);

  }

如果要在禁用日期禁用单击事件，这是一个已解决但尚未交付的错误。

If you want to disable the click event on a disabled date, this is a resolved and not delivered bug.

我认为它将在GWT 2.7版本中发布，与此同时，您可以在 com.google.gwt.user.datepicker的第77行中对其进行修补。 .client.CellGridImpl ：

I think in the GWT's 2.7 version it will be released, in the mean time you can patch it introducing in the line 77 of com.google.gwt.user.datepicker.client.CellGridImpl :

 addDomHandler(new ClickHandler() {
     @Override
     public void onClick(ClickEvent event) {
       if (isActive(Cell.this)) {
         setSelected(Cell.this);
       }
     }
  }, ClickEvent.getType());
