Beginner of smalltalk 80 - first graphic windows and GUI -2
by Hans Schueren Nov. 26, 2014

Nov. 26, 2014

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 18:00, pharo-users-request(a)lists.pharo.org wrote: > Send Pharo-users mailing list submissions to > pharo-users(a)lists.pharo.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.pharo.org/mailman/listinfo/pharo-users_lists.pharo.org > or, via email, send a message with subject or body 'help' to > pharo-users-request(a)lists.pharo.org > > You can reach the person managing the list at > pharo-users-owner(a)lists.pharo.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Pharo-users digest..." > > > Today's Topics: > > 1.

Beginner of smalltalk 80 - first graphic windows and GUI - need help
by Hans Schueren Nov. 26, 2014

Nov. 26, 2014

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

RTMultiCompositeShape + Bitmap
by rosariosm Nov. 26, 2014

Nov. 26, 2014

Hello, When i try to add a vertical/horizontal layout to a RTMultiCompositeShape that has a Bitmap shape, it cant render the layout because a RTBitmal dont understand #extent. For example: | element label bitmap composite view | label := RTLabel new text: 'hello'. bitmap := RTBitmap new form: (Form dotOfSize: 10). composite := (RTMultiCompositeShape with: label with: bitmap) vertical. element := RTElement new addShape: composite. view := RTView new add: element; open Thanks!

TextModel arrows controls

Nov. 25, 2014

Hello! I stumbled on a strange problem, when was using TextModel widget. The problem is that I can't control I-beam pointer with arrow keys inside of TextModel. They just do not work. Maybe I have to set some methods?

Named edges and nodes in a Roassal graph
by Offray Vladimir Luna CÃ¡rdenas Nov. 24, 2014

Nov. 24, 2014

Hi all. We're now in a small workshop about data narratives and I'm showing some people Roassal. I would like to have named nodes and edges in a graph. I have created a small understable graph from the object profile gallery here: http://ws.stfx.eu/8QMELFJ4V370 Anyone knows how to add names to edges and nodes in this graph? If I could have a quick answer on this one would be awesome. By the way I'm now 5:50 pm (GMT-5) in the pharo irc channel is someone pops up. Thanks, Offray

layout and other potential class-side variables
by Peter UhnÃ¡k Nov. 23, 2014

Nov. 23, 2014

So I accidentally assigned some content to 'layout' variable in class side and realized much later that it has overridden some Slot's FixedLayout. Looking up the inheritance chain (Object & ProtoObject) I couldn't find anything so I don't know where is this coming from or how it is added there. But most importantly: are there more variable names that I should be aware of that could get accidentally overridden? Thanks, Peter

Maps from Wikipedia loaded on Roassal's RTMetricMap
by Offray Vladimir Luna CÃ¡rdenas Nov. 22, 2014

Nov. 22, 2014

Hi, This Thursday and Saturday we will have a small workshop on data storytelling and I would like to present Pharo/Roassal to the people there as a tool for creating and sharing visualizations. My idea is to use Playgrounds to make agile visualization and then share them using cloud sharing at stfx and etherpads. The maps I would like to make are similar to the ones that have colored countries [1][2], but using internal country geopolitical divisions. For the case of Colombia I would like to use the ones of [3], specifically something like [4] and use the same syntax of RTMetricMap inside the country. [1] http://bit.ly/1yiedrE [2] http://bit.ly/1xTAQV0 [3] https://commons.wikimedia.org/wiki/User:Shadowxfox/Maps#Colombia [4] https://commons.wikimedia.org/wiki/File:Colombia_departamentos_otros.svg So my question is: - There is any way to upload this SGV maps and treat them as the maps already in RTMetricMap, telling the names of the internal geopolitical divisions inside a Country and how to color them according to a value and make them zoomable? - Where can I start to look to support this feature? Notice that this tries to be a leaner approach to the one I had already asked about importing maps from open street map. Thanks, Offray
