public class TranslatedSequencePanel
extends JComponent
implements SequenceRenderContext, Changeable

TranslatedSequencePanel is a panel that displays a Sequence. Its features are that it will always draw at low pixel coordinates when using Java2D to render very long sequences and it is quite fast (approximately 8x faster than SequencePanel

.

A TranslatedSequencePanel can either display the sequence from left-to-right (HORIZONTAL) or from top-to-bottom (VERTICAL). It has an associated scale which is the number of pixels per symbol and a translation which is the number of Symbols to skip before rendering starts. In order to produce a scrolling effect, the setSymbolTranslation method may be hooked up to an Adjustable such as JScrollBar or to an event listener.

The exact number of Symbols rendered depends on the width 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.

Creates a new TranslatedSequencePanel with the default settings (direction HORIZONTAL, scale 10.0 pixels per symbol, symbol translation 0, leading border 0.0, trailing border 0.0, 12 point sanserif font).

Method Detail

getSequence

public SymbolList getSequence()

isUnchanging

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

public void removeSequenceViewerMotionListener(SequenceViewerMotionListener svml)

addSequenceViewerMotionListener removes a listener for mouse motion SequenceViewerEvents.

Parameters:

getChangeSupport

protected ChangeSupport getChangeSupport(ChangeType ct)

getChangeSupport lazily instantiates a helper for change listeners.
