Contents and properties notation.

  •   The standard hierarchical navigator provides a clear visual distinction between a block's contents and the block itself.

  •   Contents are represented by a plus "+" or minus "-" icon.
  •   The block itself is represented by a unique icon denoting its type.
  •   Clicking the contents button displays a block's contents in both hierachical navigator and data flow diagrams.
  •   Clicking the properties button displays a block's properitess in a seperate window(old idea!).
