[Help-smalltalk] Newbie warning! (my first smalltalk gui object)

[Joachim Jaeckel]

Hello all,

 

I tried to code my first object in gnu-smalltalk and run into something, which I don't understand.

I tried to create a gui with the BLOX libs in the following way:

 

the object I created looks like this:

 

Smalltalk addSubspace: #Joe!

Namespace current: Joe!

 

Object subclass: #JoeTest

    instanceVariableNames: 'window'

    classVariableNames: ''

    poolDictionaries: ''

    category: ''!

 

!JoeTest methodsFor: 'actions'!

 

new

    super new.

    PackageLoader fileInPackage: 'Blox'.

    self init.

    ^self

!

init

    window := BLOX.BWindow new

!

show

    window map

!!

Namespace current: Smalltalk!

 

I "filed in" this code and tried to use it through the following statements:

Smalltalk at: #x put: 0!

x := Joe.JoeTest new!

x show!

 

but then I everytime get the error message, that my object doesn't understand the message 'show'. But the Namespace-Inspector shows my Object in the Namespace 'Joe' with all of the associated methods.

 

If I tried it directly, without creating an object, like the following, everything works fine:

Smalltalk at: #x put: 0!

PackageLoader fileInPackage: 'Blox'!

x := BLOX.BWindow new!

x map!

 

Do you have an idea, what's wrong with my code?

 

Could you suggest a book for a smalltalk newbie?

 

And: Is it possible to get a gnu-smalltalk binary for windows with Tk-Support?

 

(And I'm sorry, but how do I have to subscribe to this mailinglist?)

 

Thanks in advance,

Joachim.
