Class SpinnerValueFactory<T>

java.lang.Object

javafx.scene.control.SpinnerValueFactory<T>

Type Parameters:

T - The type of the data this value factory deals with, which must coincide with the type of the Spinner that the value factory is set on.

Direct Known Subclasses:

SpinnerValueFactory.DoubleSpinnerValueFactory, SpinnerValueFactory.IntegerSpinnerValueFactory, SpinnerValueFactory.ListSpinnerValueFactory

public abstract class SpinnerValueFactory<T>
extends Object

The SpinnerValueFactory is the model behind the JavaFX Spinner control - without a value factory installed a Spinner is unusable. It is the role of the value factory to handle almost all aspects of the Spinner, including:

• Representing the current state of the value,
• Incrementing and decrementing the value, with one or more steps per call,
• Converting text input from the user (via the Spinner editor,
• Converting objects to user-readable strings for display on screen

SpinnerValueFactory classes for some common types are provided with JavaFX, including:

• SpinnerValueFactory.IntegerSpinnerValueFactory
• SpinnerValueFactory.DoubleSpinnerValueFactory
• SpinnerValueFactory.ListSpinnerValueFactory

Since:

JavaFX 8u40

Type	Property	Description
ObjectProperty<StringConverter<T>>	converter	Converts the user-typed input (when the Spinner is editable) to an object of type T, such that the input may be retrieved via the value property.
ObjectProperty<T>	value	Represents the current value of the SpinnerValueFactory, or null if no value has been set.
BooleanProperty	wrapAround	The wrapAround property is used to specify whether the value factory should be circular.

Property Detail

value

public final ObjectProperty<T> valueProperty

Represents the current value of the SpinnerValueFactory, or null if no value has been set.

See Also:

getValue(), setValue(T)

converter

public final ObjectProperty<StringConverter<T>> converterProperty

Converts the user-typed input (when the Spinner is editable) to an object of type T, such that the input may be retrieved via the value property.

See Also:

getConverter(), setConverter(StringConverter)

wrapAround

public final BooleanProperty wrapAroundProperty

The wrapAround property is used to specify whether the value factory should be circular. For example, should an integer-based value model increment from the maximum value back to the minimum value (and vice versa).
