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,
- Incrementingand- decrementingthe value, with one or more steps per call,
- Convertingtext input from the user (via the Spinner- editor,
- Converting objects to user-readable stringsfor display on screen
SpinnerValueFactory classes for some common types are provided with JavaFX, including:

Property Details- 
valueRepresents the current value of the SpinnerValueFactory, or null if no value has been set.- See Also:
- getValue(),- setValue(T)
 
- 
converterConverts the user-typed input (when the Spinner iseditable) to an object of type T, such that the input may be retrieved via thevalueproperty.- See Also:
- getConverter(),- setConverter(StringConverter)
 
- 
wrapAroundThe 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).- See Also:
- isWrapAround(),- setWrapAround(boolean)

Method Details- 
decrementpublic abstract void decrement(int steps)Attempts to decrement thevalueby the given number of steps.- Parameters:
- steps- The number of decrements that should be performed on the value.
 
- 
incrementpublic abstract void increment(int steps)Attempts to omcrement thevalueby the given number of steps.- Parameters:
- steps- The number of increments that should be performed on the value.
