    • getNodeDimensions

      public abstract Rectangle getNodeDimensions(Object value, int row, int depth, boolean expanded, Rectangle bounds)
      Returns, by reference in bounds, the size and x origin to place value at. The calling method is responsible for determining the Y location. If bounds is null, a newly created Rectangle should be returned, otherwise the value should be placed in bounds and returned.
      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
