Class Spinner<T>

javafx.scene.control.Spinner<T>

Type Parameters:: T - The type of all values that can be iterated through in the Spinner. Common types include Integer and String.

All Implemented Interfaces:: Styleable, EventTarget, Skinnable

public class Spinner<T>
extends Control

A single line text field that lets the user select a number or an object value from an ordered sequence. Spinners typically provide a pair of tiny arrow buttons for stepping through the elements of the sequence. The keyboard up/down arrow keys also cycle through the elements. The user may also be allowed to type a (legal) value directly into the spinner. Although combo boxes provide similar functionality, spinners are sometimes preferred because they don't require a drop down list that can obscure important data, and also because they allow for features such as wrapping and simpler specification of 'infinite' data models (the SpinnerValueFactory, rather than using a ObservableList data model like many other JavaFX UI controls.

A Spinner's sequence value is defined by its SpinnerValueFactory. The value factory can be specified as a constructor argument and changed with the value factory property. SpinnerValueFactory classes for some common types are provided with JavaFX, including:

A Spinner has a TextField child component that is responsible for displaying and potentially changing the current value of the Spinner, which is called the editor. By default the Spinner is non-editable, but input can be accepted if the editable property is set to true. The Spinner editor stays in sync with the value factory by listening for changes to the value property of the value factory. If the user has changed the value displayed in the editor it is possible for the Spinner value to differ from that of the editor. To make sure the model has the same value as the editor, the user must commit the edit using the Enter key.

Example:

Spinner spinner = new Spinner(0, 10, 5);

Property Details

value

public final ReadOnlyObjectProperty<T> valueProperty

The value property on Spinner is a read-only property, as it is bound to the SpinnerValueFactory value property. Should the value factory change, this value property will be unbound from the old value factory and bound to the new one.

If developers wish to modify the value property, they may do so with code in the following form:

 
 Object newValue = ...;
 spinner.getValueFactory().setValue(newValue);

See Also:: getValue()

valueFactory

public final ObjectProperty<SpinnerValueFactory<T>> valueFactoryProperty

The value factory 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

See Also:: getValueFactory(), setValueFactory(SpinnerValueFactory)

editable

public final BooleanProperty editableProperty

The editable property is used to specify whether user input is able to be typed into the Spinner editor. If editable is true, user input will be received once the user types and presses the Enter key. At this point the input is passed to the SpinnerValueFactory converter StringConverter.fromString(String) method. The returned value from this call (of type T) is then sent to the SpinnerValueFactory.setValue(Object) method. If the value is valid, it will remain as the value. If it is invalid, the value factory will need to react accordingly and back out this change.

Default value:: false
See Also:: isEditable(), setEditable(boolean)

editor

public final ReadOnlyObjectProperty<TextField> editorProperty

The editor used by the Spinner control.

See Also:: getEditor()

promptText

public final StringProperty promptTextProperty

The prompt text to display in the Spinner, or null if no prompt text is displayed.

Default value:: Empty string
Since:: 9
See Also:: getPromptText(), setPromptText(String)

initialDelay

public final ObjectProperty<Duration> initialDelayProperty

The duration that the mouse has to be pressed on an arrow button before the next value steps. Successive step duration is set using repeat delay.

Default value:: 300ms
Since:: 11
See Also:: getInitialDelay(), setInitialDelay(Duration)

repeatDelay

public final ObjectProperty<Duration> repeatDelayProperty

The duration that the mouse has to be pressed for each successive step after the first value steps. Initial step duration is set using initial delay.

Default value:: 60ms
Since:: 11
See Also:: getRepeatDelay(), setRepeatDelay(Duration)
