got focus how to?
by Hilaire Fernandes May 24, 2012

May 24, 2012

Hello, I need to take an action when an arbitrary morph got the keyboard focus (a text morph). How can I set up such an action for a given morph? Of course I don't want to override the given morph. Ideally I want to pass a block of code to execute whenever the focus changes. Thanks Hilaire

Nautilus Subclassing Behavior?
by Daniel Uber May 22, 2012

May 22, 2012

I ran into a surprise today, and I'm not sure if it's by design or accident that I found it. In Pharo-2.0, if I'm in Nautilus looking at class side definitions, and I click on the class to Refactoring -> Class Refactoring -> Generate Subclass..., I find that a subclass is attempting to be created on MetaObject, which fails due to not understanding the #category message. This is not the same behavior as happens when looking at instance side, which created a named subclass of the class being viewed. If this is wrong behavior, I will open an issue. If this is something that surprised me because I'm new, I'd be happy to hear a rationale, and I will open an issue, since the option fails, it should either not be present, or not send category. I guess I'd just like to know what the expected behavior is when creating a subclass and viewing class side in the browser. Thanks, Daniel Uber

Fwd: CFP IWST'2012
by Marcus Denker May 21, 2012

May 21, 2012

---------- Forwarded message ---------- From: LoÃ¯c Lagadec <loic.lagadec(a)univ-brest.fr> Subject: [Esug-list] CFP IWST'2012 DearÂ colleagues & Friends, We apologize for multiple reception of this announcement. The International Workshop on Smalltalk Technologies, is a European Smalltalk User Group (ESUG) Conference joint event, that focuses on research activities - namely academic creative work undertaken on smalltalk use, and more generally on object technologies. IWST was launched in 2009, in Brest, during the 17th ESUG Conference. The second edition took place in Barcelona, and the third edition was held in 2011 at the heart of historic Edinburgh. Next edition will be in Gent, Begium this summer (28th of august). ESUG gathers groups of professionals and hobbyists who share an interest in the Smalltalk programming languages and related technologies. The goal of the workshop is to create a forum around advances or experience in Smalltalk. IWST contributes to triggering discussions and exchanges of ideas. As always, we make a point to have a very constructive paper review process that aims to provide in-depth comments and suggestions to all of them (no one-liners!) This makes it ideal to disseminate new research directions, and is a good venue for early stage PhD students to receive feedback on their work. In addition, we intent to invite best papers to a journal special issue as we did last year. Looking forward to your submissions, and to meeting you in Gent! Best regards, LoÃ¯c Lagadec & Alain Plantec Co-chairs of IWST International Workshop on Smalltalk Technologies 2012 August 28th, 2012 Gent, Belgium. ESUG 2012 Smalltalk joint event Important dates Submission deadline: June 15, 2012 Notification deadline: July 15, 2012 All accepted papers will be published in ACM DL, and the authors of the best papers will be invited to submit an extended version to a journal special issue (To Be Confirmed). Goals and scopes The goals of the workshop is to create a forum around advances or experience in Smalltalk and to trigger discussions and exchanges of ideas. Participants are invited to submit research articles. We will not enforce any length restriction. However we expect papers of two kinds: Short position papers describing emerging ideas. Long research papers with deeper description of experiments and of research results. Topics We welcome contributions on all aspects, theoretical as well as practical, of Smalltalk related topics such as: Aspect-oriented programming, Design patterns, Experience reports, Frameworks, Implementation, new dialects or languages implemented in Smalltalk, Interaction with other languages, Meta-programming and Meta-modeling, Tools Links home page: http://www.esug.org/wiki/pier/Conferences/2012/International-Workshop---IWS… submission: http://www.easychair.org/conferences/?conf=iwst2012 Publication Both submissions and final papers must be prepared using the ACM SIGPLAN 10 point format. Templates for Word and LaTeX are available at http://www.acm.org/sigs/sigplan/authorInformation.htm. This site also contains links to useful informations on how to write effective submissions.

splitter how to?
by Hilaire Fernandes May 20, 2012

May 20, 2012

Hello, I would like to add a Morph with a splitter in the DrGeo window. So far I am using LayoutFrame with fixed pixel offset to adjust the various components of a DrGeo window (see code below) Now I don't understand how I can hide the rightPanel morph, and get the area morph to take the whole horizontal extent. Message hideLeftOrTop only hide the morph but do not change the layout of remaining visible morph I can hand change the layout but I wonder if there are any proporer way to do it? All in all, I would like to simulate a collapse function in the splitter. Hilaire installTools | bar shiftY statusY rightPanel| rightPanel := Morph new color: Color blue. shiftY := DrGDefault isTablet ifFalse: [self installMenu] ifTrue: [0]. shiftY := self installToolbarsAt: shiftY. statusY := self statusbar minExtent y max: DrGDefault wheelWidth. self addMorph: area fullFrame: (LayoutFrame fractions: (0.1 @ 0 corner: 1 @ 1) offsets: (0 @ shiftY corner: DrGDefault wheelWidth negated @ statusY negated)). self addMorph: rightPanel fullFrame: (LayoutFrame fractions: (0 @ 0 corner: 0.1 @ 1) offsets: (0 @ shiftY corner: 0 @ statusY negated)). self installWheelsFrom: shiftY to: statusY. self addMorph: self statusbar fullFrame: (LayoutFrame fractions: (0 @ 1 corner: 1 @ 1) offsets: (0 @ statusY negated corner: (DrGDefault wheelWidth + DrGDefault wheelHeight) negated @ 0)). self statusbar borderStyle: (BorderStyle inset width: 1); cornerStyle: #square. self themeChanged; openInWorld

SystemWindow model methods
by Daniel Lyons May 19, 2012

May 19, 2012

Hi, I'm following the Basic Widgets tutorial in Pharo By Example 2. I see a couple of neat ways you can control the SystemWindow by passing it a model. How can I find out in the image all the different things I can control this way? The tutorial shows initial extent, whether the window can be closed and the menu items. I'd like to know how to discover all the other options. Thanks, -- Daniel Lyons

dirty hack question
by Werner Kassens May 19, 2012

May 19, 2012

Hi, i looked at a method in a package i downloaded that goes essentially like this: method:aCollection aCollection do:[:i| i satisfiesTest ifTrue[^someNumberDependingOnI] ]. ^someOtherNumberDependingOnACollection now theoretically some 'i' should always satisfy test, the ^someOtherNumber was obviously added because there is a bug in satisfiesTest and this way the bug is hardly noticable any more (its not important for my question, but someOtherNumber is perfectly logical in the general setting, if one does not understand the bug itself). i changed satisfiesTest so that there should be no more bugs in it. of course i cant be sure, hence i changed the ^someOtherNumber line to: self error:'should never be reached'. now i wonder whether that last error line would be considered a dirty hack by the usual smalltalk programmer, and if yes, what would be the usual procedure in such a case? werner
