public class PairwiseSequencePanel
extends JComponent
implements PairwiseRenderContext, Changeable, Serializable
```
A PairwiseSequencePanel is a panel that displays a pair of sequences; one sequence (the primary) may be either left-to-right (HORIZONTAL) or from top-to-bottom (VERTICAL). The other sequence (secondary) will then occupy the remaining direction. It has an associated scale which is the number of pixels per symbol and applies to both sequences. The leading and trailing borders apply to the primary sequence only.

The primary purpose of this component is to provide a means for representing graphically comparisons between two sequences. This could be anything from traditional dotplots (or variants created with lines) to a more complex layered plot involving superimposed renderers.

Each sequence has a translation which is the number of Symbols to skip before rendering starts. In order to produce a scrolling effect, the setSymbolTranslation or setSecondarySymbolTranslation method may be hooked up to an Adjustable such as JScrollBar or to an event listener.

The exact number of Symbols rendered in each sequence depends on the dimensions of the panel and the scale. Resizing the panel will cause the number of Symbols rendered to change accordingly.

The panel will fill its background to the Color defined by the setBackground() method provided that it has been defined as opaque using setOpaque().

The change event handling code is based on the original panel and other BioJava components by Matthew and Thomas.

public boolean isUnchanging(ChangeType ct)
```
    Description copied from interface: Changeable
    
    A particular ChangeType can never be raised by this Changeable.
    
    If this returns true, then it is guaranteed that change events of this type (and all child types) can never under any circumstances be fired by this Changeable instance. If it returns false, that does not mean that this type of event will or even can be raised, but that it is worth registering listeners incase.
    
    Specified by:
    
    isUnchanging in interface Changeable
    
    Parameters:
    
    ct - the ChangeType to check
    
    Returns:
    
    true if ChangeEvents of this type are guaranteed to never be fired
  - addSequenceViewerListener
```
public void addSequenceViewerListener(SequenceViewerListener svl)
```
    addSequenceViewerListener adds a listener for mouse click SequenceViewerEvents.
    
    Parameters:
    
    svl - a SequenceViewerListener.
  - removeSequenceViewerListener
```
public void removeSequenceViewerListener(SequenceViewerListener svl)
```
    removeSequenceViewerListener removes a listener for mouse click SequenceViewerEvents.
    
    Parameters:
    
    svl - a SequenceViewerListener.
  - addSequenceViewerMotionListener
```
public void addSequenceViewerMotionListener(SequenceViewerMotionListener svml)
```
    addSequenceViewerMotionListener adds a listener for mouse motion SequenceViewerEvents.
    
    Parameters:
    
    svml - a SequenceViewerMotionListener.
  - removeSequenceViewerMotionListener
```
public void removeSequenceViewerMotionListener(SequenceViewerMotionListener svml)
```
    addSequenceViewerMotionListener removes a listener for mouse motion SequenceViewerEvents.
    
    Parameters:
    
    svml - a SequenceViewerMotionListener.
  - getChangeSupport
```
protected ChangeSupport getChangeSupport(ChangeType ct)
```
    getChangeSupport lazily instantiates a helper for change listeners.
    
    Parameters:
    
    ct - a ChangeType.
    
    Returns:
    
    a ChangeSupport object.
  - hasListeners
```
protected boolean hasListeners()
```
    hasListeners returns true if there are active listeners for BioJava events.
    
    Returns:
    
    a boolean value.
  - isActive
```
protected boolean isActive()
```
    isActive returns true if both the Sequences to be rendered and the PairwiseHomologyRenderer are not null.
    
    Returns:
    
    a boolean value.
