Method Detail

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

getExpandedIcon
```
public Icon getExpandedIcon()
```

installDefaults
```
protected void installDefaults()
```

installListeners
```
protected void installListeners()
```

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.

createDefaultCellEditor

protected TreeCellEditor createDefaultCellEditor()

Creates a default cell editor.

createDefaultCellRenderer
```
protected TreeCellRenderer createDefaultCellRenderer()
```
Returns the default cell renderer that is used to do the stamping of each node.

uninstallDefaults
```
protected void uninstallDefaults()
```

uninstallListeners
```
protected void uninstallListeners()
```

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)

paintBorder

public void paintBorder(SynthContext context,

                        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

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 BasicTreeUI

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

paintDropLine
```
protected void paintDropLine(Graphics g)
```
Paints the drop line.

g - Graphics object to draw on

getRowX
```
protected int getRowX(int row,
                      int depth)
```
Returns the location, along the x-axis, to render a particular row at. The return value does not include any Insets specified on the JTree. This does not check for the validity of the row or depth, it is assumed to be correct and will not throw an Exception if the row or depth doesn't match that of the tree.

Overrides:
