Then, people adding more stuff to MorphicUIManager without: a) declaring new protocol in abstract UIManager and describing intended behavior there b) making sure it works (or has default behavior) in rest of classes, not just MorphicUIManager UI manager has too many responsibilities. But it is hard to see how we can avoid that. -- Best regards, Igor Stasenko.

[Pharo-project] FOSDEM 2013 Smalltalk devroom

by Rafael Luque

Hi Pharoers, I've noticed that FOSDEM 2013 will host an Smalltalk devroom like the previous year. Any idea about the scheduled sessions? I'd like to see tutorials related with Pharo, Seaside, Amber, Moose, etc. Thank you.

I tried to fix it. It seems we reach a disk quota on the forge :( lsebot@ff-scm-v4-prod:/home/groups/pharo/htdocs/ci/image/20$ cp -f 20459.zip latest.zip cp: closing `latest.zip': Disk quota exceeded lsebot@ff-scm-v4-prod:/home/groups/pharo/htdocs$ du -sh . 10G I will send an email to forge admins to ask more disk space.

Re: [Pharo-project] alert: not defined on non-interactive ui manager

by Christophe Demarey

Hi, alert, abort, question, etc. are defined on MorphicUIManager (with a trait) but not on UIManager itself. As Stephane said, it may causes DNU when using a NonInteractiveUIManager. For example, if you try to update a version of KeyMapping in non interactive mode, it will failed because the load method defines a post-load action using alert (see ConfigurationOfKeyMapping>resetKeymapsAndWarn). So, should we define these methods as "subclass responsability" on UIManager or do I miss something? Regards, Christophe.

I got everything working besides the list update when changed. Also, is there anyway to properly display data in columns?

[Pharo-project] alert: not defined on non-interactive ui manager

by StÃ©phane Ducasse

Hi all alert:, alert:title:... are defined on MorphicUIManager but not on NonInteractiveUIManager so this means that we get DNU when loading packages that call it. http://code.google.com/p/pharo/issues/detail?id=7205 I thought that bringing a pop up or dun in non interactive mode was killing the system but not. I'm confused but any how it would be good to have these two classes a bit more polymorphic so tell me if I'm saying something stupid. Stef

Yes, the concatenation method (it is, #,) works only with collections(*). There is no automatic casting of objects to a string representation. In the long run you'll love that. And since String "is a" Collection, you can't send #, to other object, and neither pass an argument that is not a collection. Hence the need of the "conversion"(**) to a String. (*) In some particular cases the #, method is implemented in non collection classes for convenience. (**) There is no conversion taking place, your object is returning another one, instance of String, that is supposed to represent it as a whole or some aspect of it. You might create the String every time the message is received or if it is its name, you just return it. ps: I don't know how this relates to the Morphic subject :) Esteban A. Maringolo 2013/1/2 J.
