private void	init(Debugger debugger, boolean is64Bit, BigInteger addrValue, BigInteger addrLow, BigInteger addrHigh)
private void	layoutAfter(Annotation anno, Annotation constraintAnno, Graphics g, int x, Address startAddr, int lineHeight) Lays out the given annotation after the optional constraint annotation, obeying constraints imposed by that annotation if it is specified.
private void	layoutAnnotations(List<IntervalNode> va, Graphics g, int x, Address startAddr, int lineHeight) Takes the list of currently-visible annotations (in the form of a List<intervalnode>) and lays them out given the current visible position and the already-visible annotations.
private void	layoutBefore(Annotation anno, Annotation constraintAnno, Graphics g, int x, Address startAddr, int lineHeight) Lays out the given annotation before the optional constraint annotation, obeying constraints imposed by that annotation if it is specified.
public static void	main(String[] args)
public synchronized void	makeVisible(Address addr) Makes the given address visible somewhere in the window
private Color	nextColor(Color c) Returns next color in our color palette
public synchronized void	paintComponent(Graphics g) Overrides javax.swing.JComponent.paintComponent. Calls the UI delegate's paint method, if the UI delegate is non-`null`.
private Color	prevColor(Color c) Returns previous color in our color palette

paintComponent back to summary

paintComponent	back to summary
public synchronized void paintComponent(Graphics g) Overrides javax.swing.JComponent.paintComponent. Doc from javax.swing.JComponent.paintComponent. Calls the UI delegate's paint method, if the UI delegate is non-`null`. We pass the delegate a copy of the `Graphics` object to protect the rest of the paint code from irrevocable changes (for example, `Graphics.translate`). If you override this in a subclass you should not make permanent changes to the passed in `Graphics`. For example, you should not alter the clip `Rectangle` or modify the transform. If you need to do these operations you may find it easier to create a new `Graphics` from the passed in `Graphics` and manipulate it. Further, if you do not invoke super's implementation you must honor the opaque property, that is if this component is opaque, you must completely fill in the background in an opaque color. If you do not honor the opaque property you will likely see visual artifacts. The passed in `Graphics` object might have a transform other than the identify transform installed on it. In this case, you might get unexpected results if you cumulatively apply another transform.
