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)

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)

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()

Overrides:

recalculateIfInsetsChanged in class BasicSliderUI

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,
                        int x,

                          Graphics g,
                          Rectangle thumbBounds)

Paints the slider thumb.

Parameters:
