Method Detail
-
createUI
public static ComponentUI createUI(JComponent c)
Returns a UI.- Parameters:
c- a component- Returns:
- a UI
-
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 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 classComponentUI- Parameters:
g- theGraphicsobject used for paintingc- 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:
paintin classComponentUI- Parameters:
g- theGraphicsobject used for paintingc- 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 paintedg- theGraphicsobject used for painting- See Also:
update(Graphics,JComponent)
-
paintTrack
protected void paintTrack(SynthContext context, Graphics g, Rectangle trackBounds)
Paints the scrollbar track.- Parameters:
context- context for the component being paintedg-Graphicsobject used for paintingtrackBounds- bounding box for the track
-
paintThumb
protected void paintThumb(SynthContext context, Graphics g, Rectangle thumbBounds)
Paints the scrollbar thumb.- Parameters:
context- context for the component being paintedg-Graphicsobject used for paintingthumbBounds- bounding box for the thumb
-
getPreferredSize
public 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 classBasicScrollBarUI- Parameters:
c- theJScrollBarthat'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)
