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
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]

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.

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.

Hi Casey,
The target is Browser, which does not override the method.
The hierarchy is: ProtoObject, Object, Model, StringHolder (has the method), CodeHolder, Browser, et seq.
I put the halt in StringHolder>>perform:orSendTo: and that didn't bring up the debugger.
There are 13 implementers of perform:orSendTo: and I can put a halt in each one in order to start the research, but I don't understand why the hierarchy seems to be bypassed.

Hi Dan,
That doesn't sound quite right.
#perform:orSendTo: is probably overridden in Browser, but... have you looked to see if there's an implementation of it on Object or maybe ProtoObject or something like that?
I'm pretty sure that #perform: and cousins are usually general.
Not sure (on a cellphone) without looking at an actual running system, but try looking up the inheritance chain for another implementation of the same selector. That might help.
Let me know either way, when I get back to a real computer I'll look into it for you if you don't get it figured out by then.
Good hunting!
Casey

I want to follow the code and I put a halt in "#perform:orSendTo:" but the debugger never opened. What gives?
