ScrollBar (openjfx 8.0.202 API)

java.lang.Object
- javafx.scene.Node
- - javafx.scene.Parent
  - - javafx.scene.layout.Region
    - - javafx.scene.control.Control
      - javafx.scene.control.ScrollBar

All Implemented Interfaces:

Styleable, EventTarget, Skinnable

Direct Known Subclasses:

VirtualScrollBar
```
public class ScrollBar
extends Control
```
Either a horizontal or vertical bar with increment and decrement buttons and a "thumb" with which the user can interact. Typically not used alone but used for building up more complicated controls such as the ScrollPane and ListView.
ScrollBar sets focusTraversable to false.

This example creates a vertical ScrollBar :
```
 import javafx.scene.control.ScrollBar;

 ScrollBar s1 = new ScrollBar();
 s1.setOrientation(Orientation.VERTICAL);
 
```
Implementation of ScrollBar According to JavaFX UI Control API Specification
Since:

JavaFX 2.0

```
public void adjustValue(double position)
```
    Adjusts the value property by blockIncrement. The position is the fractional amount between the min and max. For example, it might be 50%. If #minProperty min were 0 and #maxProperty max were 100 and value were 25, then a position of .5 would indicate that we should increment value by blockIncrement. If value were 75, then a position of .5 would indicate that we should decrement value by blockIncrement.
  - increment
```
public void increment()
```
    Increments the value of the ScrollBar by the unitIncrement
  - decrement
```
public void decrement()
```
    Decrements the value of the ScrollBar by the unitIncrement
  - createDefaultSkin
```
protected Skin<?> createDefaultSkin()
```
    Create a new instance of the default skin for this control. This is called to create a skin for the control if no skin is provided via CSS -fx-skin or set explicitly in a sub-class with setSkin(...).
    
    Overrides:
    
    createDefaultSkin in class Control
    
    Returns:
    
    new instance of default skin for this control. If null then the control will have no skin unless one is provided by css.
  - getClassCssMetaData
```
public static List<CssMetaData<? extends Styleable,?>> getClassCssMetaData()
```
    Returns:
    
    The CssMetaData associated with this class, which may include the CssMetaData of its super classes.
    
    Since:
    
    JavaFX 8.0
  - getControlCssMetaData
```
public List<CssMetaData<? extends Styleable,?>> getControlCssMetaData()
```
    Overrides:
    
    getControlCssMetaData in class Control
    
    Returns:
    
    unmodifiable list of the controls css styleable properties

  - impl_cssGetFocusTraversableInitialValue
```
@Deprecated
protected Boolean impl_cssGetFocusTraversableInitialValue()
```
    Deprecated.
    
    Most Controls return true for focusTraversable, so Control overrides this method to return true, but ScrollBar returns false for focusTraversable's initial value; hence the override of the override. This method is called from CSS code to get the correct initial value.
    
    Overrides:
    
    impl_cssGetFocusTraversableInitialValue in class Control

    Overrides:
    
    queryAccessibleAttribute in class Control
    
    Parameters:
    
    attribute - the requested attribute
    
    parameters - optional list of parameters

    the value for the requested attribute

```
public void executeAccessibleAction(AccessibleAction action,
                                    Object... parameters)
```
    Description copied from class: Node
    
    This method is called by the assistive technology to request the action indicated by the argument should be executed.
    This method is commonly overridden by subclasses to implement action that are required for a specific role.
    If a particular action is not handled, the super class implementation must be called.
    
    Overrides:
    
    executeAccessibleAction in class Control
    
    Parameters:
    
    action - the action to execute
    
    parameters - optional list of parameters
