public SynthScrollBarUI()
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 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 classComponentUI
- 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)
paintTrack
protected void paintTrack(SynthContext context, Graphics g, Rectangle trackBounds)
Paints the scrollbar track.
- Parameters:
-
context
- context for the component being painted -
g
-Graphics
object used for painting -
trackBounds
- 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 painted -
g
-Graphics
object used for painting -
thumbBounds
- 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 (non null
) 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 preferredSize
is only computed once, subsequent calls to this method just return a cached size.
- Overrides:
-
getPreferredSize
in classBasicScrollBarUI
- Parameters:
-
c
- theJScrollBar
that's delegating this method to us - Returns:
- the preferred size of a Basic JScrollBar
