Method Summary
`MouseEvent` | `getMouseEvent()` Get the mouse event that caused this.
`List` | `getPath()` Get the list of SequenceRenderer instances that were passed through to produce this event
`int` | `getPos()` Get the offset within the sequence - the symbol index.
`Object` | `getTarget()` Get the Object that was the target of the mouse gesture or null if the mouse is not gesturing over any recognizable rendered object.

Constructor Detail

### SequenceViewerEvent

    public SequenceViewerEvent(Object source,
                               Object target,
                               int pos,
                               MouseEvent mouseEvent,
                               List path)

  Construct a SequenceViewerEvent with the given source, target, mouseEvent and path.

  Parameters:
    `source` - the event source, presumably a GUI component
    `target` - an Object that is the target of the gesture - a feature, or {alignment, label, index} or some other structure, or null if there is no obvious target
    `pos` - the position (offset) within the sequence
    `mouseEvent` - the MouseEvent that caused this event to be produced
    `path` - a List of SequenceRenderer instances passed through to reach this event source

Method Detail

### getPath

    public List getPath()

  Get the list of SequenceRenderer instances that were passed through to produce this event

  Returns:
    a List of SequenceRenderer instances

### getTarget

    public Object getTarget()

  Get the Object that was the target of the mouse gesture or null if the mouse is not gesturing over any recognizable rendered object.

  Returns:
    the Object gestured at by the mouse event

### getPos

    public int getPos()

  Get the offset within the sequence - the symbol index. This is not guaranteed to be within the legal range of symbol indices.

  Returns:
    the position of the gesture in sequence coordinates

### getMouseEvent

    public MouseEvent getMouseEvent()

  Get the mouse event that caused this.

  Returns:
    the MouseEvent that caused this gesture to be noticed

### toString

    public String toString()

  Overrides:
    `toString` in class `EventObject`
