Class ListProperty<E>

java.lang.Object
javafx.beans.binding.ListExpression<E>
javafx.beans.property.ReadOnlyListProperty<E>
javafx.beans.property.ListProperty<E>
Type Parameters:
E - the type of the List elements
All Implemented Interfaces:
Iterable<E>, Collection<E>, List<E>, Observable, Property<ObservableList<E>>, ReadOnlyProperty<ObservableList<E>>, ObservableListValue<E>, ObservableObjectValue<ObservableList<E>>, ObservableValue<ObservableList<E>>, WritableListValue<E>, WritableObjectValue<ObservableList<E>>, WritableValue<ObservableList<E>>, ObservableList<E>
Direct Known Subclasses:
ListPropertyBase
public abstract class ListProperty<E>
extends ReadOnlyListProperty<E>
implements Property<ObservableList<E>>, WritableListValue<E>
This class provides a full implementation of a Property wrapping an ObservableList. The value of a ListProperty can be get and set with ObservableObjectValue.get(), ListExpression.getValue(), WritableObjectValue.set(Object), and setValue(ObservableList). A property can be bound and unbound unidirectional with Property.bind(javafx.beans.value.ObservableValue) and Property.unbind(). Bidirectional bindings can be created and removed with bindBidirectional(Property) and unbindBidirectional(Property). The context of a ListProperty can be read with ReadOnlyProperty.getBean() and ReadOnlyProperty.getName().
Since:
JavaFX 2.1

  • Constructor Details

    • ListProperty

      public ListProperty()
      Creates a default ListProperty.

  • Method Details

    • setValue

      public void setValue​(ObservableList<E> v)
      Set the wrapped value.
      Specified by:
      setValue in interface WritableValue<E>
      Parameters:
      v - The new value

    • bindBidirectional

      public void bindBidirectional​(Property<ObservableList<E>> other)
      Create a bidirectional binding between this Property and another one. Bidirectional bindings exists independently of unidirectional bindings. So it is possible to add unidirectional binding to a property with bidirectional binding and vice-versa. However, this practice is discouraged.

      It is possible to have multiple bidirectional bindings of one Property.

      JavaFX bidirectional binding implementation use weak listeners. This means bidirectional binding does not prevent properties from being garbage collected.

      Specified by:
      bindBidirectional in interface Property<E>
      Parameters:
      other - the other Property

    • unbindBidirectional

      public void unbindBidirectional​(Property<ObservableList<E>> other)
      Remove a bidirectional binding between this Property and another one. If no bidirectional binding between the properties exists, calling this method has no effect. It is possible to unbind by a call on the second property. This code will work: 
           property1.bindBirectional(property2);
     property2.unbindBidirectional(property1);
      Specified by:
      unbindBidirectional in interface Property<E>
      Parameters:
      other - the other Property

    • toString

      public String toString()
      Returns a string representation of this ListProperty object.
      Overrides:
      toString in class ReadOnlyListProperty<E>
      Returns:
      a string representation of this ListProperty object.
