Beginner wants to start graphic windows in, Smalltalk 80 - need help - 2
by Hans Schueren 26 Nov '14

26 Nov '14

Hello , here is Hans , The Byte Surfer , the smalltalk code is from books of year 1992 and 1993 1988 and 1987. I have a lot of books around the world . ALL of the Topic SMALLTALK 80. Only 80 !!! Because i am a absolute beginner and want to learn smalltalk 80. I realized that thing have changed. for example GUI programming Mosttimes there is a optional library needed for creation. There is a optional IDE i know , for those things. No Matter ! I dont know anything about the NEW TOOLS and Replacements in actual Smalltalk Engineering like PHARO. Please tell me what i have to learn. What is GUI IDE in Pharo. Do i have to learn Morpic. What else for Window and Buttons design ? The Pharo ( and actual squeak ) have very much weight for a beginner. Is it right , that all " NEW STUFF " is decribed in the two manuals : Pharo by Example + Deep into Pharo. Or is there any other actual description about "Up to date programming Pharo" ???? Sincerely Your Friend Hans The Byte Surfer PS. Wish to have Smalltalk 80 from XEROX 1987 here. ha ha ha On 26.11.2014 19:39, beginners-request(a)lists.squeakfoundation.org wrote: > Send Beginners mailing list submissions to > beginners(a)lists.squeakfoundation.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.squeakfoundation.org/mailman/listinfo/beginners > or, via email, send a message with subject or body 'help' to > beginners-request(a)lists.squeakfoundation.org > > You can reach the person managing the list at > beginners-owner(a)lists.squeakfoundation.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Beginners digest..." > > > Today's Topics: > > 1.

Beginner wants to start graphic windows in Smalltalk 80 - need help
by Hans Schueren 26 Nov '14

26 Nov '14

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] Greetings Hans The Byte Surfer
