Hello Hans,

Can you please say what book or paper you are using? Also check if your
learning material specifies what version of Smalltalk was used for the
examples.

Your examples look like some version of the MVC user interface, which
was the original (and still very interesting) user interface in Smalltalk
and Squeak. Squeak still provides some support for MVC, so for example
there probably is some equivalent to the ScheduledWindow class used in
your example below. You may also be interested in other user interface
approaches, such as Morphic, which are very different from MVC.
