Constructor Detail

SynthScrollBarUI

public SynthScrollBarUI()

Class is disabled.

Method Detail

createUI

public static ComponentUI createUI(JComponent c)

Class is disabled.

protected void configureScrollBarColors()

Class is disabled.

Overrides:

configureScrollBarColors in class BasicScrollBarUI

getContext

public SynthContext getContext(JComponent c)

Class is disabled.

Description copied from interface: SynthUI

Returns the Context for the specified component.

Specified by:

getContext in interface SynthUI

Parameters:

c - Component requesting SynthContext.

Returns:

SynthContext describing component.

getSupportsAbsolutePositioning

public boolean getSupportsAbsolutePositioning()

Class is disabled.

Description copied from class: BasicScrollBarUI

Indicates whether the user can absolutely position the thumb with a mouse gesture (usually the middle mouse button).

Overrides:

getSupportsAbsolutePositioning in class BasicScrollBarUI

Returns:

true if a mouse gesture can absolutely position the thumb

update

public void update(Graphics g,
                   JComponent c)

Class is disabled.

Description copied from class: ComponentUI

Notifies this UI delegate that it is time to paint the specified component. This method is invoked by JComponent when the specified component is being painted.

By default this method fills the specified component with its background color if its opaque property is true, and then immediately calls paint. In general this method need not 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 context in which to paint

c - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components

See Also:

ComponentUI.paint(java.awt.Graphics, javax.swing.JComponent), JComponent.paintComponent(java.awt.Graphics)

paint

public void paint(Graphics g,
                  JComponent c)

Class is disabled.

Description copied from class: ComponentUI

Paints the specified component appropriately for the look and feel. This method is invoked from the ComponentUI.update method when the specified component is being painted. Subclasses should override this method and use the specified Graphics object to render the content of the component.

Overrides:

paint in class BasicScrollBarUI

Parameters:

g - the Graphics context in which to paint

c - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components

See Also:

ComponentUI.update(java.awt.Graphics, javax.swing.JComponent)

paint

protected void paint(SynthContext context,
                     Graphics g)

Class is disabled.

Paints the specified component.

Parameters:

context - context for the component being painted

g - Graphics object used for painting

paintBorder

public void paintBorder(SynthContext context,
                        Graphics g,
                        int x,
                        int y,
                        int w,
                        int h)

Class is disabled.

Description copied from interface: SynthUI

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

paintTrack

protected void paintTrack(SynthContext context,
                          Graphics g,
                          Rectangle trackBounds)

Class is disabled.

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)

Class is disabled.

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)

Class is disabled.

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 class BasicScrollBarUI

Parameters:

c - the JScrollBar that'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)

getMinimumThumbSize

protected Dimension getMinimumThumbSize()

Class is disabled.

Description copied from class: BasicScrollBarUI

Returns the smallest acceptable size for the thumb. If the scrollbar becomes so small that this size isn't available, the thumb will be hidden.

Warning : the value returned by this method should not be be modified, it's a shared static constant.

Overrides:

getMinimumThumbSize in class BasicScrollBarUI

Returns:

The smallest acceptable size for the thumb.

See Also:

BasicScrollBarUI.getMaximumThumbSize()

createDecreaseButton

protected JButton createDecreaseButton(int orientation)

Class is disabled.

Overrides:

createDecreaseButton in class BasicScrollBarUI

createIncreaseButton

protected JButton createIncreaseButton(int orientation)

Class is disabled.

Overrides:

createIncreaseButton in class BasicScrollBarUI

setThumbRollover

protected void setThumbRollover(boolean active)

Class is disabled.

Description copied from class: BasicScrollBarUI

Sets whether or not the mouse is currently over the thumb.

Overrides:

setThumbRollover in class BasicScrollBarUI

Parameters:

active - True indicates the thumb is currently active.

propertyChange

public void propertyChange(PropertyChangeEvent e)

Class is disabled.

Description copied from interface: PropertyChangeListener

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.
