Actually a better design in this case, for gui work, is to create custom
renderer components for biojava objects.
For example, in a JTree that views features, use
class FeatureTreeCellRenderer extends DefaultTreeCellRenderer {
public Component getTreeCellRendererComponent(JTree tree, Object value, ...) {
JLabel l = (JLabel) super.getTreeCellRendererComponent(tree,value,...);
Feature f = (Feature) value;
l.setText(f.getName());
return l;
}
}
JTree tree = new JTree();
tree.setCellRenderer(new FeatureTreeCellRenderer());
or something similar.
