Method Detail- 
createUIpublic static ComponentUI createUI(JComponent c) Returns a UI.- Parameters:
- c- a component
- Returns:
- a UI
 
 - 
updatepublic void update(Graphics g, JComponent c) Notifies this UI delegate to repaint the specified component. This method paints the component background, then calls thepaint(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 paintmethod.- Overrides:
- updatein class- ComponentUI
- Parameters:
- g- the- Graphicsobject used for painting
- c- the component being painted
- See Also:
- paint(SynthContext,Graphics)
 
 - 
paintpublic 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:
- paintin class- ComponentUI
- Parameters:
- g- the- Graphicsobject used for painting
- c- the component being painted
- See Also:
- paint(SynthContext,Graphics)
 
 - 
paintprotected void paint(SynthContext context, Graphics g) Paints the specified component.- Parameters:
- context- context for the component being painted
- g- the- Graphicsobject used for painting
- See Also:
- update(Graphics,JComponent)
 
 - 
paintTrackprotected void paintTrack(SynthContext context, Graphics g, Rectangle trackBounds) Paints the scrollbar track.- Parameters:
- context- context for the component being painted
- g-- Graphicsobject used for painting
- trackBounds- bounding box for the track
 
 - 
paintThumbprotected void paintThumb(SynthContext context, Graphics g, Rectangle thumbBounds) Paints the scrollbar thumb.- Parameters:
- context- context for the component being painted
- g-- Graphicsobject used for painting
- thumbBounds- bounding box for the thumb
 
 - 
getPreferredSizepublic Dimension getPreferredSize(JComponent c) A vertical scrollbar's preferred width is the maximum of preferred widths of the (nonnull) increment/decrement buttons, and the minimum width of the thumb. The preferred height is the sum of the preferred heights of the same parts. The basis for the preferred size of a horizontal scrollbar is similar.The preferredSizeis only computed once, subsequent calls to this method just return a cached size.- Overrides:
- getPreferredSizein class- BasicScrollBarUI
- Parameters:
- c- the- JScrollBarthat's delegating this method to us
- Returns:
- the preferred size of a Basic JScrollBar
- See Also:
- BasicScrollBarUI.getMaximumSize(javax.swing.JComponent),- ComponentUI.getMinimumSize(javax.swing.JComponent)
