Constructor Details

SynthButtonUI

public SynthButtonUI()

Constructs a SynthButtonUI.

Method Details

createUI

public static ComponentUI createUI(JComponent c)

Creates a new UI object for the given component.

Parameters:

c - component to create UI object for

Returns:

the UI object

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.

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 ComponentUI

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

getDefaultIcon

protected Icon getDefaultIcon(AbstractButton b)

Returns the default icon. This should not callback to the JComponent.

Parameters:

b - button the icon is associated with

Returns:

default icon

getIcon

protected Icon getIcon(AbstractButton b)

Returns the Icon to use for painting the button. The icon is chosen with respect to the current state of the button.

Parameters:

b - button the icon is associated with

Returns:

an icon

getSizingIcon

protected Icon getSizingIcon(AbstractButton b)

Returns the Icon used in calculating the preferred/minimum/maximum size.

Parameters:

b - specifies the AbstractButton used when calculating the preferred/minimum/maximum size.

Returns:

the Icon used in calculating the preferred/minimum/maximum size.

propertyChange

public void propertyChange(PropertyChangeEvent e)

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.
