      public abstract Rectangle getNodeDimensions(Object value, int row, int depth, boolean expanded, Rectangle bounds)

      Parameters:
      value - the value to be represented
      row - row being queried
      depth - the depth of the row
      expanded - true if row is expanded, false otherwise
      bounds - a Rectangle containing the size needed to represent value
      Returns:
      a Rectangle containing the node dimensions, or null if node has no dimension
