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(), 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).

    • setValue

      public void setValue(Number v)
      Set the wrapped value.
      Specified by:
      setValue in interface WritableIntegerValue
      Specified by:
      setValue in interface WritableValue<Number>
      Parameters:
      v - The new value
    • bindBidirectional

      public void bindBidirectional(Property<Number> 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<Number>
      Parameters:
      other - the other Property
    • unbindBidirectional

      public void unbindBidirectional(Property<Number> 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<Number>
      Parameters:
      other - the other Property
    • 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.
