Re: [Pharo-users] "whenSelectedItemChanged:" in Spec

by PBKResearch

Steve How did you get the source code for the examples? Pages 12-13 of the "Spec UI Framework" booklet give the code for the methods of class WidgetClassList, and there we find: WidgetClassList >> whenSelectedItemChanged: aBlock list whenSelectedItemChanged: aBlock This looks very much like the 'when....' methods of all the other subclasses of ComposablePresenter. It should at least do something when activated.

"whenSelectedItemChanged:" in Spec

by Steve Quezadas

I am running through the "Spec UI Framework" tutorial, and in it has a widget class inherited from "ComposablePresenter" (ComposablePresenter subclass: #WidgetClassList). But for some reason the "whenSelectedItemChanged:" method call does not execute when I select any item on the GUI list. Is there anything I'm missing? I posted this earlier on the list, and someone suggested I try "whenActivatedDo:" or "whenSelectionChangedDo:", but it doesn't do anything as well. The code looks like this: whenSelectedItemChanged: aBlock Transcript show: 'should get here; cr. I am using Pharo 7. - Steve

Hi all, I'm working with artifacts, but I got an error. I have a pdf's generator which works very well, but recently I discovered that it has problems with special characters, specifically this: "Ä" since if some text has this symbol the pdf is generated in white, I tried some encodings to the text between them UTF8, Latin1, Latin2 and with these encodings the pdf manages to generate well; however the character does not look like it should look (It can be appear like this Ã or Ã¦). Does anyone know how to solve this problem? Thanks very much, Evelyn

I am not expert in algorithm, so I would consider myself a simple user. I have developed complex software for some times and I have never seen the need of having a binary search tree. I guess this is probably partly because of my lack of expertise in binary search tree and partly because experts in binary search trees assume that people know what it is about and in what it is useful. > > My question is, when should a programmer ever need to use binary search tree?

Re: [Pharo-users] Test Completion has been added to Pharo 8 - please test!

by Myroslava Romaniuk

Aha ok! Please let us know if you have a specific example of when it fails. We removed completion for temp declaration but when using already declared temps, as far as i tested, it seems to work. So would be grateful for a counterexample.
