日期时间的 SWT 数据绑定

我想使用两个 DateTime 控件显示一个 java.util.Date - 一个显示日期，一个显示时间。

我尝试在此处使用数据绑定来设置在控件中输入的值。我尝试将控件绑定到日期，如下所示：

IObservableValue getPostponeDateDayObserveValue = SWTObservables.observeSelection(getPostponeDate());
IObservableValue getPostponeTargetDateDateObserveValue = PojoObservables.observeValue(this, "postponeTargetDate");
bindingContext.bindValue(getPostponeDateDayObserveValue, getPostponeTargetDateDateObserveValue, null, null);
    //
IObservableValue getPostponeTimeSecondsObserveValue = SWTObservables.observeSelection(getPostponeTime());
IObservableValue postponeTargetDateSecondsObserveValue = PojoObservables.observeValue(this, "postponeTargetDate");
bindingContext.bindValue(getPostponeTimeSecondsObserveValue, postponeTargetDateSecondsObserveValue, null, null);

这里发生的情况是，日期与正确的日期或正确的时间相关，具体取决于稍后更改的控件。是否可以将两个日期时间控件（一个用于日期，一个用于时间）绑定到同一日期。

感谢您的支持。

I want to display a java.util.Date using two DateTime controls - one displaying the date and one the time.

I try to use databinding here to set the values entered in the controls. I try to bind the controls to the date as follows:

IObservableValue getPostponeDateDayObserveValue = SWTObservables.observeSelection(getPostponeDate());
IObservableValue getPostponeTargetDateDateObserveValue = PojoObservables.observeValue(this, "postponeTargetDate");
bindingContext.bindValue(getPostponeDateDayObserveValue, getPostponeTargetDateDateObserveValue, null, null);
    //
IObservableValue getPostponeTimeSecondsObserveValue = SWTObservables.observeSelection(getPostponeTime());
IObservableValue postponeTargetDateSecondsObserveValue = PojoObservables.observeValue(this, "postponeTargetDate");
bindingContext.bindValue(getPostponeTimeSecondsObserveValue, postponeTargetDateSecondsObserveValue, null, null);

What happens here is that the date corries the correct date or the correct time depending on which control was changed later. Is there a possibility to bind two datetime controls (one for date one for time) to the same date.

Thanks for your support.
