如何使用com.google.gwt.user.datepicker.client.DateBox限制可用的日期范围

根据我收到的建议，以下是我想出的方法：将可选日期限制为仅当日和之后。这适用于GWT 2.1.1

final DateBox dateBox = new DateBox();dateBox.addValueChangeHandler(new ValueChangeHandler<Date>(){    @Override    public void onValueChange(final ValueChangeEvent<Date> datevalueChangeEvent)    {        if (datevalueChangeEvent.getValue().before(today()))        { dateBox.setValue(today(), false);        }    }});dateBox.getDatePicker().addShowRangeHandler(new ShowRangeHandler<Date>(){    @Override    public void onShowRange(final ShowRangeEvent<Date> dateShowRangeEvent)    {        final Date today = today();        Date d = zeroTime(dateShowRangeEvent.getStart());        while (d.before(today))        { dateBox.getDatePicker().setTransientEnabledonDates(false, d); d = nextDay(d);        }    }});

为了完整

static

private static Date today(){    return zeroTime(new Date());}private static Date zeroTime(final Date date){    return DateTimeFormat.getFormat("yyyyMMdd").parse(DateTimeFormat.getFormat("yyyyMMdd").format(date));}private static Date nextDay(final Date date){    return zeroTime(new Date(date.getTime() + 24 * 60 * 60 * 1000));}
