date - 如何在 JavaFX 中将 LocalDate 双向绑定(bind)到 TextField

Question

我正在尝试绑定(bind) ObjectProperty<LocalDate>在 DTO 上到 TextField我很难让它发挥作用。

这就是我的设置方式:

dateOfBirthTextField.setTextFormatter(new TextFormatter<>(new LocalDateEnhancedStringConverter()));

person.birthdayProperty().bindBidirectional(dateOfBirthTextField.textProperty(), new LocalDateEnhancedStringConverter());

但这给了我以下编译错误:

The method bindBidirectional(Property) in the type ObjectProperty is not applicable for the arguments (StringProperty, LocalDateEnhancedStringConverter)

不太确定下一步要尝试什么？

Answer 1

根据 JavaDoc:

public <T> void bindBidirectional(Property<T> other, StringConverter<T> converter)

Create a bidirectional binding between this StringProperty and another arbitrary property. Parameters:

other - the other Property

converter - the StringConverter used to convert between this StringProperty and the other Property

(粗体是我的)

所以你应该以相反的顺序进行绑定(bind)，绑定(bind) StringProperty来自文本字段到“其他”属性，即生日属性:

dateOfBirthTextField.textProperty()
    .bindBidirectional(
        person.birthdayProperty(), 
        new LocalDateEnhancedStringConverter());
