An object-oriented computing environment stores information relating to objects
in a data file, and manipulates the information in the data file through a suitable
user interface. The interface permits a user to completely redesign a program structure
by adding or removing parents of an object through simple actions such as menu
commands or drag and drop operations. The precedence of parents in a heterarchy
can be reordered, again through drag and drop operation. A new parent can be spliced
between an existing parent and its children. Properties and handlers can be moved
to appropriate levels of the program structure through simple operations, and the
user can be provided with choices to make appropriate functionality changes to
individual objects, as desired.
