Class PairwiseOverlayRenderer

Method Details

• addRenderer

  public void addRenderer(PairwiseSequenceRenderer renderer) throws ChangeVetoException

  addRenderer adds a renderer.

  Parameters:

  renderer - a PairwiseSequenceRenderer.

  Throws:

  ChangeVetoException - if an error occurs.

• removeRenderer

  public void removeRenderer(PairwiseSequenceRenderer renderer) throws ChangeVetoException

  removeRenderer removes a renderer.

  Parameters:

  renderer - a PairwiseSequenceRenderer.

  Throws:

  ChangeVetoException - if an error occurs.

• clearRenderers

  public void clearRenderers() throws ChangeVetoException

  clearRenderers removes all the renderers.

  Throws:

  ChangeVetoException - if an error occurs.

• paint

  public void paint(Graphics2D g2, PairwiseRenderContext context)

  paint applies all renderers in the order in which they were added.

  Specified by:

  paint in interface PairwiseSequenceRenderer

  Parameters:

  g2 - a Graphics2D.

  context - a PairwiseRenderContext.

• getChangeSupport

  protected ChangeSupport getChangeSupport(ChangeType ct)

  Description copied from class: AbstractChangeable

  Called to retrieve the ChangeSupport for this object.

  Your implementation of this method should have the following structure:

   ChangeSupport cs = super.getChangeSupport(ct);
  
   if(someForwarder == null && ct.isMatching(SomeInterface.SomeChangeType)) {
     someForwarder = new ChangeForwarder(...
  
     this.stateVariable.addChangeListener(someForwarder, VariableInterface.AChange);
   }
  
   return cs;
   

  It is usual for the forwarding listeners (someForwarder in this example) to be transient and lazily instantiated. Be sure to register & unregister the forwarder in the code that does the ChangeEvent handling in setter methods.

  Overrides:

  getChangeSupport in class AbstractChangeable

• processMouseEvent

  public SequenceViewerEvent processMouseEvent(PairwiseRenderContext context, MouseEvent me, List path)

  processMouseEvent produces a SequenceViewerEvent in response to a mouse gesture. The list of renderers are probed in the order in which they were added and the first renderer to accept the event will return.

  Specified by:

  processMouseEvent in interface PairwiseSequenceRenderer

  Parameters:

  context - a PairwiseRenderContext.

  me - a MouseEvent that caused the request.

  path - a List of PairwiseSequenceRenderer instances passed through so far.

  Returns:

  a SequenceViewerEvent encapsulating the mouse gesture.
