Class BoundedSubtreeUI

java.lang.Object
  javax.swing.plaf.ComponentUI
      org.annotation.agschema.graphics.vtree.ui.VTreeUI
          org.annotation.agschema.graphics.vtree.ui.BoundedSubtreeUI

All Implemented Interfaces:

java.util.EventListener, java.beans.PropertyChangeListener, TreeMutationListener, VTreeExpansionListener, VTreeSelectionListener

public class BoundedSubtreeUI

extends VTreeUI

implements java.beans.PropertyChangeListener, TreeMutationListener, VTreeExpansionListener, VTreeSelectionListener

This UI draws each subtree in its own rectangle. The size of the rectangle is proportional to the number of leaves in the subtree, so the leaves appear evenly spaced. This implementation is optimized for speed, and uses memory proportional to the size of the tree being drawn.

TODO - Make a memory efficient counterpart to this.
