</span>Hello Hans,<br>
<br>
Can you please say what book or paper you are using? Also check if your<br>
learning material specifies what version of Smalltalk was used for the<br>
examples.<br>
<br>
Your examples look like some version of the MVC user interface, which<br>
was the original (and still very interesting) user interface in Smalltalk<br>
and Squeak. Squeak still provides some support for MVC, so for example<br>
there probably is some equivalent to the ScheduledWindow class used in<br>
your example below. You may also be interested in other user interface<br>
approaches, such as Morphic, which are very different from MVC.<br>
