public class MetalSliderUI
extends BasicSliderUI

A Java L&F implementation of SliderUI.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the `java.beans` package. Please see `XMLEncoder`.

Constructor Detail

### MetalSliderUI

    public MetalSliderUI()

Method Detail

### createUI

    public static ComponentUI createUI(JComponent c)

  Description copied from class: `ComponentUI`
  Returns an instance of the UI delegate for the specified component. Each subclass must provide its own static `createUI` method that returns an instance of that UI delegate subclass. If the UI delegate subclass is stateless, it may return an instance that is shared by multiple components. If the UI delegate is stateful, then it should return a new instance per component. The default implementation of this method throws an error, as it should never be invoked.

### installUI

    public void installUI(JComponent c)

  Description copied from class: `ComponentUI`
  Configures the specified component appropriate for the look and feel. This method is invoked when the `ComponentUI` instance is being installed as the UI delegate on the specified component. This method should completely configure the component for the look and feel, including the following:
  1. Install any default property values for color, fonts, borders, icons, opacity, etc. on the component. Whenever possible, property values initialized by the client program should not be overridden.
  2. Install a `LayoutManager` on the component if necessary.
  3. Create/add any required sub-components to the component.
  4. Create/install event listeners on the component.
  5. Create/install a `PropertyChangeListener` on the component in order to detect and respond to component property changes appropriately.
  6. Install keyboard UI (mnemonics, traversal, etc.) on the component.
  7. Initialize any appropriate instance data.

  Overrides:
    `installUI` in class `BasicSliderUI`
  Parameters:
    `c` - the component where this UI delegate is being installed
  See Also:
    `ComponentUI.uninstallUI(javax.swing.JComponent)`, `JComponent.setUI(javax.swing.plaf.ComponentUI)`, `JComponent.updateUI()`

### createPropertyChangeListener

    protected PropertyChangeListener createPropertyChangeListener(JSlider slider)

  Overrides:
    `createPropertyChangeListener` in class `BasicSliderUI`

### paintThumb

    public void paintThumb(Graphics g)

  Overrides:
    `paintThumb` in class `BasicSliderUI`

### paintTrack

    public void paintTrack(Graphics g)

  Overrides:
    `paintTrack` in class `BasicSliderUI`

### paintFocus

    public void paintFocus(Graphics g)

  Overrides:
    `paintFocus` in class `BasicSliderUI`

### getThumbSize

    protected Dimension getThumbSize()

  Overrides:
    `getThumbSize` in class `BasicSliderUI`

### getTickLength

    public int getTickLength()

  Gets the height of the tick area for horizontal sliders and the width of the tick area for vertical sliders. BasicSliderUI uses the returned value to determine the tick area rectangle.

  Overrides:
    `getTickLength` in class `BasicSliderUI`

### getTrackWidth

    protected int getTrackWidth()

  Returns the shorter dimension of the track.

### getTrackLength

    protected int getTrackLength()

  Returns the longer dimension of the slide bar. (The slide bar is only the part that runs directly under the thumb)

### getThumbOverhang

    protected int getThumbOverhang()

  Returns the amount that the thumb goes past the slide bar.

### scrollDueToClickInTrack

    protected void scrollDueToClickInTrack(int dir)

  Description copied from class: `BasicSliderUI`
  This function is called when a mousePressed was detected in the track, not in the thumb. The default behavior is to scroll by block. You can override this method to stop it from scrolling or to add additional behavior.

  Overrides:
    `scrollDueToClickInTrack` in class `BasicSliderUI`

### paintMinorTickForHorizSlider

    protected void paintMinorTickForHorizSlider(Graphics g,
                                                Rectangle tickBounds,
                                                int x)

  Overrides:
    `paintMinorTickForHorizSlider` in class `BasicSliderUI`

### paintMajorTickForHorizSlider

    protected void paintMajorTickForHorizSlider(Graphics g,
                                                Rectangle tickBounds,
                                                int x)

  Overrides:
    `paintMajorTickForHorizSlider` in class `BasicSliderUI`

### paintMinorTickForVertSlider

    protected void paintMinorTickForVertSlider(Graphics g,
                                               Rectangle tickBounds,
                                               int y)

  Overrides:
    `paintMinorTickForVertSlider` in class `BasicSliderUI`

### paintMajorTickForVertSlider

    protected void paintMajorTickForVertSlider(Graphics g,
                                               Rectangle tickBounds,
                                               int y)
