Class PairwiseSequencePanel
- All Implemented Interfaces:
ImageObserver

,Serializable

,PairwiseRenderContext
,SequenceRenderContext
,Changeable
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
Symbol
s 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 Symbol
s rendered in each
sequence depends on the dimensions of the panel and the
scale. Resizing the panel will cause the number of
Symbol
s 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.

isUnchanging
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

ct
- the ChangeType to check- Returns:
- true if ChangeEvents of this type are guaranteed to never be fired
