Constructor Details

SynthSliderUI

protected SynthSliderUI(JSlider c)
Constructs a SynthSliderUI.
Parameters:
c - a slider

Method Details

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

uninstallDefaults

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

layout

protected void layout()
Lays out the slider.

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

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 ComponentUI
Parameters:
g - the Graphics object used for painting
c - the component being painted
See Also:

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:

paintBorder

public void paintBorder(SynthContext context, Graphics g, int x, int y, int w, int h)
Paints the border.
Specified by:
paintBorder in interface SynthUI
Parameters:
context - a component context
g - Graphics to paint on
x - the X coordinate
y - the Y coordinate
w - width of the border
h - 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
g - Graphics object used for painting
thumbBounds - bounding box for the thumb

paintTrack

protected void paintTrack(SynthContext context, Graphics g, Rectangle trackBounds)
Paints the slider track.
Parameters:
context - context for the component being painted
g - Graphics object used for painting
trackBounds - bounding box for the track

propertyChange

public void propertyChange(PropertyChangeEvent e)
This method gets called when a bound property is changed.
Specified by:
propertyChange in interface PropertyChangeListener
Parameters:
e - A PropertyChangeEvent object describing the event source and the property that has changed.
