public static ComponentUI createUI(JComponent c)
Creates a new UI object for the given component.

installDefaults in class BasicSliderUI
protected void uninstallDefaults(JSlider slider)
Uninstalls default setting. This method is called when a LookAndFeel is uninstalled.

public int getBaseline(JComponent c,
int width,
int height) Returns the baseline.

c - JComponent baseline is being requested forwidth - the width to get the baseline forheight - the height to get the baseline forJComponent.getBaseline(int, int)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.
getPreferredSize in class BasicSliderUI
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 componentsJComponent.getPreferredSize(), LayoutManager.preferredLayoutSize(java.awt.Container)
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.

xPositionForValue in class BasicSliderUI
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.
yPositionForValue in class BasicSliderUI
value - the slider value to get the location fortrackY - y-origin of the tracktrackHeight - the height of the trackpublic 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.
valueForYPosition in class BasicSliderUI
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.

public SynthContext getContext(JComponent c)
Returns the Context for the specified component.
getContext in interface SynthUI
c - Component requesting SynthContext.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.

g - the Graphics object used for paintingc - the component being paintedpaint(SynthContext,Graphics)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.
