## Constructor Details

### SynthDesktopPaneUI

public SynthDesktopPaneUI()
Constructs a `SynthDesktopPaneUI`.

## 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. This implementation does nothing.

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

### propertyChange

public void propertyChange(PropertyChangeEvent evt)
This method gets called when a bound property is changed.

Specified by:
  `propertyChange` in interface `PropertyChangeListener`
Parameters:
  `evt` - A PropertyChangeEvent object describing the event source and the property that has changed.
