Which is exactly the reverse of how it should be -- a rectangle
adds the feature of having different lengthed edges to a square,
this is why a square is a subclass of rectangle.
Subclassing is for specialization, not generalization.
Yes...and the Outlineview adds the special ability of being able to
collapse/expand rows of items. It is a specialization, built upon the
basics of a table.
If it were the opposite, it would be very strange; the NSTableView
would simply restrict ability (ie: the ability to expand/collapse
items).
