public SynthLookAndFeel() 
{
        factory = new DefaultSynthStyleFactory();
        _handler = new Handler();
}

Creates a SynthLookAndFeel.

For the returned SynthLookAndFeel to be useful you need to invoke load to specify the set of SynthStyles, or invoke setStyleFactory.

                                url, null, defaultsMap);
}

Loads the set of SynthStyles that will be used by this SynthLookAndFeel. Path based resources are resolved relatively to the specified URL of the style. For example an Image would be resolved by new URL(synthFile, path). Refer to Synth File Format for more information.

 public  void load(InputStream input,

{
        if (resourceBase == null) {

}

Loads the set of SynthStyles that will be used by this SynthLookAndFeel. resourceBase is used to resolve any path based resources, for example an Image would be resolved by resourceBase.getResource(path). Refer to Synth File Format for more information.

 static  void resetSelectedUI() 
{
        selectedUI = null;
}

Clears out the selected UI that was last set in setSelectedUI.

    boolean focused,
    boolean enabled,
    boolean rollover) 
{

            selectedUIState = SynthConstants.SELECTED;
            if (focused) {
                selectedUIState |= SynthConstants.FOCUSED;
            }
        }
        else if (rollover && enabled) {
            selectedUIState |=

            }
            else {
                selectedUIState |= SynthConstants.DISABLED;
            }
        }
}

Used by the renderers. For the most part the renderers are implemented as Labels, which is problematic in so far as they are never selected. To accomodate this SynthLabelUI checks if the current UI matches that of selectedUI (which this methods sets), if it does, then a state as set by this method is returned. This provides a way for labels to have a state other than selected.

 public static  void setStyleFactory(SynthStyleFactory cache) 
{
        // We assume the setter is called BEFORE the getter has been invoked
        // for a particular AppContext.

            lastContext = context;
            context.put(STYLE_FACTORY_KEY, cache);
        }
}

Sets the SynthStyleFactory that the UI classes provided by synth will use to obtain a SynthStyle.

{
        String eName = event.getPropertyName();
        if ("name" == eName) {

                     shouldUpdateStyleOnAncestorChanged());
        }
        return false;
}

Returns true if the Style should be updated in response to the specified PropertyChangeEvent. This forwards to shouldUpdateStyleOnAncestorChanged as necessary.

 public boolean shouldUpdateStyleOnAncestorChanged() 
{
        return false;
}

Returns whether or not the UIs should update their SynthStyles from the SynthStyleFactory when the ancestor of the JComponent changes. A subclass that provided a SynthStyleFactory that based the return value from getStyle off the containment hierarchy would override this method to return true.

 public  void uninitialize() 
{
        KeyboardFocusManager.getCurrentKeyboardFocusManager().
            removePropertyChangeListener(_handler);
        // We should uninstall the StyleFactory here, but unfortunately
        // there are a handful of things that retain references to the
        // LookAndFeel and expect things to work
        super.uninitialize();
}

Called by UIManager when this look and feel is uninstalled.

 static  void update(SynthContext state,
    Graphics g) 
{
        paintRegion(state, g, null);
}

A convenience method that handles painting of the background. All SynthUI implementations should override update and invoke this method.

 static SynthStyle updateStyle(SynthContext context,
    SynthUI ui) 
{
        SynthStyle newStyle = getStyle(context.getComponent(),
                                       context.getRegion());
        SynthStyle oldStyle = context.getStyle();

            if (oldStyle != null) {
                oldStyle.uninstallDefaults(context);
            }

            newStyle.installDefaults(context, ui);
        }
        return newStyle;
}

A convience method that will reset the Style of StyleContext if necessary.

 public static  void updateStyles(Component c) 
{
        _updateStyles(c);
        c.repaint();
}

Updates the style associated with c, and all its children. This is a lighter version of SwingUtilities.updateComponentTreeUI.

 static  void updateSubregion(SynthContext state,
    Graphics g,
    Rectangle bounds) 
{
        paintRegion(state, g, bounds);
}

A convenience method that handles painting of the background for subregions. All SynthUI's that have subregions should invoke this method, than paint the foreground.
