如何在Java FX中将表单映射到bean

Question

I have a form made with fxml, it has like 20 fields. (Ie Person) and I have my controller with the 20 fields (one for every field) o want to know if there is a way to box all these fields in a unique bean like PersonBean. Actually I have to set all the fields to the bean manually in the initialize method.

Something like in the Id of the fxml input put something like "person.name".

Answer 1

Not 100% sure but try something like:

text="${controller.person.name}"

where person is a property of the controller and name is a property of PersonBean.

See:

• http://docs.oracle.com/javafx/2/api/javafx/fxml/doc-files/introduction_to_fxml.html#expression_binding
• Binding a Label's text property (in an FXML file) to an IntegerProperty (in a controller)

You might need to provide JavaFX properties such as

ObjectProperty<PersonBean> personProperty();
StringProperty nameProperty();

but maybe there is also some support for plain JavaBeans properties.
