public abstract class IntegerProperty extends ReadOnlyIntegerProperty implements Property<Number>, WritableIntegerValue
Property
wrapping an int
value.
The value of an IntegerProperty
can be get and set with ObservableIntegerValue.get()
,
IntegerExpression.getValue()
, WritableIntegerValue.set(int)
, and 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 bindBidirectional(Property)
and
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 setValue(java.lang.Number)
.

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.

public void unbindBidirectional(Property<Number> other)
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);

IntegerProperty
object.public static IntegerProperty integerProperty(Property<Integer> property)
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
Note: null values in the source property will be interpreted as 0
Another approach is to convert the IntegerProperty to ObjectProperty using
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);

asObject()
public ObjectProperty<Integer> asObject()
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());
