I was just browsing FormEditor. A lot has changed since the original MVC, some to make it compatible with Morphic, e.g., the instance method 'edit' of Form
edit "Open a form editor on this form. "
Project current formEdit: self
As you can see, the current project has some responsibilities.
Project current -> a MVCProject (Unnamed) in a ControlManager
current "Answer the project that is currently being used."
^CurrentProject
a class variable of Project.
For Project:
formEdit: aForm "Start up an instance of the form editor on a form."
self subclassResponsibility
Subclasses of Project are MVCProject and MorphicProject
For MVCProject:
formEdit: aForm "Start up an instance of the FormEditor on a form..."
FormEditor openOnForm: aForm
Poking around in FormEditor and its associated classes, while tedious, can yield useful information on how these views, models, and controllers inter-operate.

To whom it may concern ,
may i ask for some help about standard graphic routines ?
As a beginner i just have learned all the first level SYNTAX of smalltalk 80.
Now , you can imagine , i am interested in writing little GUI windows and graphics for
placing some text in the right positions.
Theese are the statements i have studied from my material.
Does anybody know why the statements not work?
Are there any "replacements" for the syntax that i posted here as
example ?
Have a nice day
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.
Dave
HERE ARE THE EXAMPLES :
| window | window := ScheduledWindow new. window component: 'Hello World' asComposedText. window open
| window | window := ScheduledWindow new. window label: 'Fenster ohne Inhalt'. window minimumSize: 200 @ 100; maximumSize: 400 @ 300. window open
displayOn: aGraphicsContext 1 to: 10 do: [:i| aGraphicsContext translation printString asComposedText displayOn: aGraphicsContext. aGraphicsContext translateBy: 15 @ 15]
Greetings
