Java javax.swing.plaf.synth Class SynthSliderUI（JDK8）

Constructor Detail

• SynthSliderUI

  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)

  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)

  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)

  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)

  protected int yPositionForValue(int value,
                                  int trackY,
                                  int trackHeight)

  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)

  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)

  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()

• getContext

  public SynthContext getContext(JComponent c)

  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)

• paint

  protected void paint(SynthContext context,
                       Graphics g)

  Paints the specified component.

  Parameters:

  context - context for the component being painted

  g - the Graphics object used for painting

  See Also:

  update(Graphics,JComponent)

• paintBorder

  public void paintBorder(SynthContext context,
                          Graphics g,
