Sven, Thanks for this, I was unaware of the MultiColumnListModel. I notice that setting colors has no effect here either. I remember from the video that overriding theme colors is still an issue in Spec, but I can move forward.

Nicolai, This code works perfectly. This is pretty-much exactly what I did. Except that I left the m openWithSpec message send where it was in the example, just before instantiating the columns. (see below) The example clearly needs updating. The way that you did it makes perfect sense, thank you.

Re: [Pharo-users] Learning Spec

by Craig

Hi Sven, I count myself as a beginner with Pharo, although I've been dabbling with Pharo UI choices for a few months now. Like Sebastian, I wrote Spec off as too immature for prime-time, but I too come from the commercial world, so maybe my expectations were unrealistic. So I took the time to learn Spec. My very first requirement is to display some data in a grid or table like manner, so I took a look at the TreeModel, and tried to adapt one of the examples to fit. However, whenever I try to add a third column to the model, I get a "Subscript Out of Bounds". I also tried to change the oddRowColor, but it had no effect. I hope that is specific enough for you.

GSOC 2015 Call for Ideas

by Serge Stinckwich

Dear pharoers, this year Pharo consortium (and community) is going to take part in a Google Summer of Code event[1] as a standalone organization. This is an opportunity to promote Pharo, get some job done and have students paid. Currently we are at the most important stage as we are preparing the organization application, and hoping that we will be accepted and granted decent amount of project slots. Everyone can help with application by submitting ideas for student projects. Current list can be found at: https://github.com/pharo-project/pharo-project-proposals/blob/master/Topics… It is in STON format, and result is being generated at: http://gsoc.pharo.org/ Please add your ideas following the format of existing projects and open a pull request with them (you will need a github account). Preferably submit ideas with possible mentors, but if none are available at the moment ideas without mentors are also welcome. The template to submit projects is : PharoTopic new title: 'The name of your project; contact: 'email address'; supervisors: 'Supervisors names'; keywords: 'keywords separated by spaces; context: 'a description of the context of the project'; goal: 'description of the goal'; level: 'Beginner or Intermediate or Advanced'; yourself. We will need a lot of projects/idea before February 20th 2015, the deadline for applying to GSOC 2015. Do not hesitate to ask questions. Administrators of this yearâs application are Serge Stinckwich <serge.stinckwich(a)gmail.com> and Yuriy Tymchuk <yuriy.tymchuk(a)me.com> If you don't know how to edit the list, please send your project following the template to the administrators.

Re: [Pharo-users] On GUI design and how to benchmark it

by Thierry Goubier

Hi Sebastian, a guy which starts by saying that no GUI toolkit of significance were written in FP, and forget to link or cite Garnet (by B. Myers) (Common Lisp) is, how to say, intriguing. Doesn't bode well for the well researched :( Thierry Le 15/02/2015 14:08, Sebastian Sastre a Ã©crit : > Hi guys, > > I saw the interest in GUI lately and today I come across this really > well researched master thesis paper that can put some light on how good > we can perform in the GUI spectrum in terms of practicality, > expressivity and productivity > > Introduction > > Even though OOP was born with the SIMULA programming language in the > 1960s [15], it was Smalltalk that coupled GUI development with the OOP > paradigm [25].
