SynthScrollPaneUI

public SynthScrollPaneUI()

Constructs a SynthScrollPaneUI.

Method Details

createUI

public static ComponentUI createUI(JComponent x)

Creates a new UI object for the given component.

Parameters:

x - component to create UI object for

Returns:

the UI object

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(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 class BasicScrollPaneUI

Parameters:

g - the Graphics 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 - the Graphics object used for painting

See Also:

• update(Graphics,JComponent)

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

installDefaults

protected void installDefaults(JScrollPane scrollpane)

Installs default properties.

Overrides:

installDefaults in class BasicScrollPaneUI

Parameters:

scrollpane - an instance of JScrollPane

installListeners

protected void installListeners(JScrollPane c)

Registers listeners.

Overrides:

installListeners in class BasicScrollPaneUI

Parameters:

c - an instance of JScrollPane

uninstallDefaults

protected void uninstallDefaults(JScrollPane c)

Uninstalls default properties.

Overrides:

uninstallDefaults in class BasicScrollPaneUI

Parameters:

c - an instance of JScrollPane

uninstallListeners

protected void uninstallListeners(JComponent c)

Unregisters listeners.

Overrides:

uninstallListeners in class BasicScrollPaneUI

Parameters:

c - a component

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.

propertyChange

public void propertyChange(PropertyChangeEvent e)

Description copied from interface: PropertyChangeListener

This method gets called when a bound property is changed.

Specified by:

propertyChange in interface PropertyChangeListener

Parameters:
