protected SynthSliderUI(JSlider c)
```
- Method Detail
  - createUI
```
public static ComponentUI createUI(JComponent c)
```
    Creates a new UI object for the given component.
    
    Parameters:
    c - component to create UI object for
    
    Returns:
    the UI object
  - installDefaults
```
protected void installDefaults(JSlider slider)
```
    Overrides:
    
    installDefaults in class BasicSliderUI
  - uninstallDefaults
```
protected void uninstallDefaults(JSlider slider)
```
    Uninstalls default setting. This method is called when a LookAndFeel is uninstalled.
    
    Overrides:
    
    uninstallDefaults in class BasicSliderUI
  - installListeners
```
protected void installListeners(JSlider slider)
```
    Overrides:
    
    installListeners in class BasicSliderUI
  - uninstallListeners
```
protected void uninstallListeners(JSlider slider)
```
    Overrides:
    
    uninstallListeners in class BasicSliderUI
  - createTrackListener
```
protected BasicSliderUI.TrackListener createTrackListener(JSlider s)
```
    Overrides:
    
    createTrackListener in class BasicSliderUI
  - getBaseline
```
public int getBaseline(JComponent c,
              int width,
              int height)
```
    Description copied from class: BasicSliderUI
    
    Returns the baseline.
    
    Overrides:
    
    getBaseline in class BasicSliderUI
    
    Parameters:
    c - JComponent baseline is being requested for
    width - the width to get the baseline for
    height - the height to get the baseline for
    
    Returns:
    baseline or a value < 0 indicating there is no reasonable baseline
    See Also:
    JComponent.getBaseline(int, int)
  - getPreferredSize
```
public Dimension getPreferredSize(JComponent c)
```
    Description copied from class: ComponentUI
    
    Returns the specified component's preferred size appropriate for the look and feel. If null is returned, the preferred size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method returns null.
    
    Overrides:
    
    getPreferredSize in class BasicSliderUI
    
    Parameters:
    c - the component whose preferred size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
    See Also:
    JComponent.getPreferredSize(), LayoutManager.preferredLayoutSize(java.awt.Container)
  - getMinimumSize
```
public Dimension getMinimumSize(JComponent c)
```
    Description copied from class: ComponentUI
    
    Returns the specified component's minimum size appropriate for the look and feel. If null is returned, the minimum size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method invokes getPreferredSize and returns that value.
    
    Overrides:
    
    getMinimumSize in class BasicSliderUI
    
    Parameters:
    c - the component whose minimum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
    
    Returns:
    a Dimension object or null
    See Also:
    JComponent.getMinimumSize(), LayoutManager.minimumLayoutSize(java.awt.Container), ComponentUI.getPreferredSize(javax.swing.JComponent)
  - calculateGeometry
```
protected void calculateGeometry()
```
    Overrides:
    
    calculateGeometry in class BasicSliderUI
  - layout
```
protected void layout()
```
    Lays out the slider.
  - calculateThumbLocation
```
protected void calculateThumbLocation()
```
    Overrides:
    
    calculateThumbLocation in class BasicSliderUI
  - setThumbLocation
```
public void setThumbLocation(int x,
                    int y)
```
    Overrides:
    
    setThumbLocation in class BasicSliderUI
  - xPositionForValue
```
protected int xPositionForValue(int value)
```
    Overrides:
    
    xPositionForValue in class BasicSliderUI
  - yPositionForValue
```
protected int yPositionForValue(int value,
                    int trackY,
                    int trackHeight)
```
    Description copied from class: BasicSliderUI
    
    Returns the y location for the specified value. No checking is done on the arguments. In particular if trackHeight is negative undefined results may occur.
    
    Overrides:
    
    yPositionForValue in class BasicSliderUI
    
    Parameters:
    value - the slider value to get the location for
    trackY - y-origin of the track
    trackHeight - the height of the track
  - valueForYPosition
```
public int valueForYPosition(int yPos)
```
    Description copied from class: BasicSliderUI
    
    Returns the value at the y position. If yPos is beyond the track at the the bottom or the top, this method sets the value to either the minimum or maximum value of the slider, depending on if the slider is inverted or not.
    
    Overrides:
    
    valueForYPosition in class BasicSliderUI
  - valueForXPosition
```
public int valueForXPosition(int xPos)
```
    Description copied from class: BasicSliderUI
    
    Returns the value at the x position. If xPos is beyond the track at the left or the right, this method sets the value to either the minimum or maximum value of the slider, depending on if the slider is inverted or not.
    
    Overrides:
    
    valueForXPosition in class BasicSliderUI
  - getThumbSize
```
protected Dimension getThumbSize()
```
    Overrides:
    
    getThumbSize in class BasicSliderUI
  - recalculateIfInsetsChanged
```
protected void recalculateIfInsetsChanged()
```
    Overrides:
    
    recalculateIfInsetsChanged in class BasicSliderUI
  - getContext
```
public SynthContext getContext(JComponent c)
```
    Description copied from interface: SynthUI
    
    Returns the Context for the specified component.
    
    Specified by:
    
    getContext in interface SynthUI
    
    Parameters:
    c - Component requesting SynthContext.
    
    Returns:
    SynthContext describing component.
  - update
```
public void update(Graphics g,
          JComponent c)
```
    Notifies this UI delegate to repaint the specified component. This method paints the component background, then calls the paint(SynthContext,Graphics) method.
    In general, this method does not need to be overridden by subclasses. All Look and Feel rendering code should reside in the paint method.
    
    Overrides:
    
    update in class ComponentUI
    
    Parameters:
    g - the Graphics object used for painting
    c - the component being painted
    See Also:
    paint(SynthContext,Graphics)
  - paint
```
public void paint(Graphics g,
         JComponent c)
```
    Paints the specified component according to the Look and Feel.
    This method is not used by Synth Look and Feel. Painting is handled by the paint(SynthContext,Graphics) method.
    
    Overrides:
    
    paint in class BasicSliderUI
    
    Parameters:
    g - the Graphics object used for painting
    c - the component being painted
    See Also:
    paint(SynthContext,Graphics)
