Constructors
SynthSliderUI
protected SynthSliderUI(JSlider c)
Methods
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 classBasicSliderUI
uninstallDefaults
protected void uninstallDefaults(JSlider slider)
Uninstalls default setting. This method is called when a LookAndFeel
is uninstalled.
- Overrides:
-
uninstallDefaults
in classBasicSliderUI
installListeners
protected void installListeners(JSlider slider)
- Overrides:
-
installListeners
in classBasicSliderUI
uninstallListeners
protected void uninstallListeners(JSlider slider)
- Overrides:
-
uninstallListeners
in classBasicSliderUI
createTrackListener
protected BasicSliderUI.TrackListener createTrackListener(JSlider s)
- Overrides:
-
createTrackListener
in classBasicSliderUI
getBaseline
public int getBaseline(JComponent c, int width, int height)
Returns the baseline.
- Overrides:
-
getBaseline
in classBasicSliderUI
- 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 classBasicSliderUI
- 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 classBasicSliderUI
- 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 ornull
- See Also:
-
JComponent.getMinimumSize()
,LayoutManager.minimumLayoutSize(java.awt.Container)
,ComponentUI.getPreferredSize(javax.swing.JComponent)
calculateGeometry
protected void calculateGeometry()
- Overrides:
-
calculateGeometry
in classBasicSliderUI
layout
protected void layout()
Lays out the slider.
calculateThumbLocation
protected void calculateThumbLocation()
- Overrides:
-
calculateThumbLocation
in classBasicSliderUI
setThumbLocation
public void setThumbLocation(int x, int y)
- Overrides:
-
setThumbLocation
in classBasicSliderUI
xPositionForValue
protected int xPositionForValue(int value)
- Overrides:
-
xPositionForValue
in classBasicSliderUI
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 classBasicSliderUI
- 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 classBasicSliderUI
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 classBasicSliderUI
getThumbSize
protected Dimension getThumbSize()
- Overrides:
-
getThumbSize
in classBasicSliderUI
recalculateIfInsetsChanged
protected void recalculateIfInsetsChanged()
- Overrides:
-
recalculateIfInsetsChanged
in classBasicSliderUI
getContext
public SynthContext getContext(JComponent c)
Returns the Context for the specified component.
- Specified by:
-
getContext
in interfaceSynthUI
- 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 classComponentUI
- Parameters:
-
g
- theGraphics
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 classBasicSliderUI
- Parameters:
-
g
- theGraphics
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
- theGraphics
object used for painting - See Also:
update(Graphics,JComponent)
paintBorder
public void paintBorder(SynthContext context, Graphics g, int x, int y, int w, int h)
Paints the border.
- Specified by:

- height of the border
paintThumb
protected void paintThumb(SynthContext context, Graphics g, Rectangle thumbBounds)
Paints the slider thumb.
- Parameters:
-
context
- context for the component being painted -
