Hi,

May someone who is or has done GUI development in Squeak recently, may
you please recommend the best way to go about implementing a GUI app?
The swiki is information packed, but I would like to get the
perspective of a human being on this one.

Hi !
Actually it is probably a very simple Squeak concept which I haven't
understood, yet.
Serving as an simple example, I would like to write a method, which accepts a
Class as argument and which return the Superclass of that Class.
The problem is that the argument must be an instance of
Hello Warakorn,
try:
Smalltalk at: #MonthMorph inspect

A better alternative would be
Smalltalk classNamed: 'Object'
avoiding the low level #at: and #asSymbol protocol. Does some more
checks, too.

This doesn't work either, because again (Smalltalk at: aClassName) is returning
just a ByteString but not (e.g.) Object classor (e.g.) ClassBuilder
class .
Lets assume in the calling method is written:
returnSuperClass: '#Object'.
Note: the Argument must be an instance of String.
What makes you think it does not return a class object? It does.
But note that you have to use a symbol (#Object) not a String
('Object') when you use #at:. Of course. '#Object' does not make any
sense. If you use #classNamed:, both a String and a Symbol will work.

I guess there's no mouse button for this in MVC?
If you are using the mouse anyway, what is wrong with a simple drag? Did you
try to double-click items such as a word or at the beginning of a line or at
the end (bottom) of all the text?

Now, I just tried MVC in a 3.9 image on the Mac, and it is seriously
broken, I saw freezes, sluggishness, missed clicks etc. Looks like
nobody has ventured into these fields for a while.

Ditto here under XP, which answers my question, but
Dear All --
I need your help. I'm teaching my 10 year-old niece eToys. I'm
running a Squeak version in FreeBSD that has Wonderland, but on our
Macintosh, on version 3.9, we can't find Wonderland.
We're using the computers sort of like in a class, side by side, so
it would be nice to synchronize
The method Object#class does what you want. Since it is defined on
Object you can send the message to any object, including a string.
returnSuperClass: aClassName
|aSuperClass|
aSuperClass := aClassName class superclass.
^ aSuperClass.
The above method body could be a one liner:
Doh! Sorry, didn't read carefully (or the whole thread).
Bert is right:

Hi all,
It's the beginning of this semester and we, at university are starting
some courses using Squeak. The first one will start this Friday and will
have a month of duration. I was talking today with the people who will
take the course and they expressed their interest specially in the
