Direct Known Subclasses:

IntegerPropertyBase, JavaBeanIntegerProperty

public abstract class IntegerProperty
extends ReadOnlyIntegerProperty
implements Property<Number>, WritableIntegerValue

This class defines a Property wrapping an int value.

The value of an IntegerProperty can be get and set with ObservableIntegerValue.get(), ObservableValue.getValue(), WritableIntegerValue.set(int), and WritableIntegerValue.setValue(Number).

A property can be bound and unbound unidirectional with Property.bind(ObservableValue) and Property.unbind(). Bidirectional bindings can be created and removed with Property.bindBidirectional(Property) and Property.unbindBidirectional(Property).

The context of a IntegerProperty can be read with ReadOnlyProperty.getBean() and ReadOnlyProperty.getName().

Note: setting or binding this property to a null value will set the property to "0.0". See WritableIntegerValue.setValue(java.lang.Number).

Since:

JavaFX 2.0

Method Detail

toString

public String toString()

Returns a string representation of this IntegerProperty object.

Overrides:

toString in class ReadOnlyIntegerProperty

Returns:

a string representation of this IntegerProperty object.

integerProperty

public static IntegerProperty integerProperty(Property<Integer> property)

Returns a IntegerProperty that wraps a Property and is bidirectionally bound to it. Changing this property will result in a change of the original property.

This is very useful when bidirectionally binding an ObjectProperty<Integer> and a IntegerProperty.

   IntegerProperty integerProperty = new SimpleIntegerProperty(1);
   ObjectProperty<Integer> objectProperty = new SimpleObjectProperty<>(2);

   // Need to keep the reference as bidirectional binding uses weak references
   IntegerProperty objectAsInteger = IntegerProperty.integerProperty(objectProperty);

   integerProperty.bindBidirectional(objectAsInteger);

 

Another approach is to convert the IntegerProperty to ObjectProperty using asObject() method.

Note: null values in the source property will be interpreted as 0

Parameters:

property - The source Property

Returns:

A IntegerProperty that wraps the Property

Throws:

NullPointerException - if property is null

Since:

JavaFX 8.0

asObject()

asObject

public ObjectProperty<Integer> asObject()

Creates an ObjectProperty that bidirectionally bound to this IntegerProperty. If the value of this IntegerProperty changes, the value of the ObjectProperty will be updated automatically and vice-versa.

Can be used for binding an ObjectProperty to IntegerProperty.

   IntegerProperty integerProperty = new SimpleIntegerProperty(1);
   ObjectProperty<Integer> objectProperty = new SimpleObjectProperty<>(2);

   objectProperty.bind(integerProperty.asObject());
 

Overrides:

asObject in class ReadOnlyIntegerProperty

Returns:

the new ObjectProperty
