org.biojava.bio.gui.sequence.FeatureBlockSequenceRenderer
public class FeatureBlockSequenceRenderer
FeatureBlockSequenceRenderer
forms a bridge between
Sequence
rendering and Feature
rendering. It is a SequenceRenderer
which iterates
through a Sequence
's Feature
s and makes
method calls on a FeatureRenderer
.

AbstractChangeable
Your implementation of this method should have the following structure:
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.
ChangeSupport cs = super.getChangeSupport(ct);
if(someForwarder == null && ct.isMatching(SomeInterface.SomeChangeType)) {
someForwarder = new ChangeForwarder(...
this.stateVariable.addChangeListener(someForwarder, VariableInterface.AChange);
}
return cs;

public double getDepth(SequenceRenderContext src)
SequenceRenderer
The depth may vary between sequence panels - for example based upon sequence length. Each line of information in the SequenceRendererContext only renders a region of the sequence. The depth for one complete line may be different from that for another due to the sequence having more or less information in that region to show. For example, a feature renderer implementation may chose to collapse down to a depth of zero pixels if there are no features to render within a region.

SequenceRenderer
A SequenceRenderer that performs any form of coordinate remapping should ensure that it appropriately transforms the mouse event. However, in the SequenceViewerEvent returned, the MouseEvent should be in untransformed coordinates.
The SequenceRenderer implementation should append itself to the path list before constructing the SequenceViewerEvent.
