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.

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.

public void propertyChange(PropertyChangeEvent event)
This method gets called when a bound property is changed.
propertyChange in interface PropertyChangeListener
event - A PropertyChangeEvent object describing the event source and the property that has changed.protected void paintDropLine(Graphics g)
Paints the drop line.

g - Graphics object to draw onprotected 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.
getRowX in class BasicTreeUI
row - Row to return x location fordepth - Depth of the row
