Is there a tandard way to attach context menus
by Herbert König 04 Nov '11

04 Nov '11

Hello all, is there a standard way to attach a context menu to a morph? It's fairly easy to do by checking for yellowButtonPressed and manually firing up a MenuMorph. But it is sufficient to implement #addCustomMenuItems:hand: to get an enhanced Halo menu while #addYellowButtonMenuItemsTo:event: and #hasYellowButtonMenu don't help. So is there a predefined way without everybody doing his own? Thanks, Herbert mailto:herbertkoenig@gmx.net

Omnibrowser help
by Rob Rothwell 14 Aug '11

14 Aug '11

Are there some tips/documentation somewhere on getting the most out of the OmniBrowser? The MulitpleSelection browser looks interesting (sort of like the tabbed browser in VisualWorks), but I don't quite understand its behaviour and what method it decides to show in which pane when you move around or save changes. On the same topic, can anyone point me toward how I could add a new item to the class context menu in the OmniBrowser? I want to add a new template selection menu item (like "new class template" and "new trait template") because I have created a method that creates TWO classes at the same time for an Aida application (A domain model class AND its associated WebApp class). Thanks, Rob Rothwell

Resources with Monticello
by Matthias Korn 15 Apr '10

15 Apr '10

Hi all, how does one work with resources (e.g. image files (GIFs, ...)) used in the application when working with Monticello and in general? Right now I have them on my hard drive and they are read live into Squeak when they are needed. Of course, others don't have the files at hand when working in a distributed fashion. What are the best practices in regard of distribution/packaging as well as performance?

3.10 image hang
by Prashanth Hebbar 28 Sep '09

28 Sep '09

Hi: I am using Squeak 3.10 on a Windows XP (2 GB RAM, 2 Ghz, Intel) While trying to save a project, I got a DNU and the image hung. The Debug walkthrough showed the error in "isSystemDefined" method. On further examination, I found a LowSpaceDebug.txt in my default directory. I had similar problems earlier both on XP and Vista. Image would freeze and the CPU usage would show 100%. That problem continues in my new machine which has Ubuntu. I suspect that the image is entering an infinite loop. There is little or no documentation of this problem. I have been working on a 3.8 and 3.9 images for some time now. I checked mantis and came across a fix for the TransformationMorph behavious which would solve the freeze problem but I don't see how it is relevant to what I am facing. I may be missing something obvious. Can someone please help me. Regards, -- Prashanth Hebbar Bangalore

[ANN] STicky
by Hernán Morales Durand 26 Sep '09

STicky is a pluggable real-time evaluator and/or translator workspace aimed to learn languages. For a quick overview please take a look at the presentation video: http://www.youtube.com/watch?v=b9uUIEaGyoU The Smalltalk evaluator could be useful in learning courses or for newbies typing expressions, but other translators/evaluators may help with more advanced usage, it all depends of the source and target languages you're using. Some default external translators, which does the real job, were included : Smalltalk to JavaScript (ST2JS by Diego Gomez Deck) Smalltlak to Java (Smalltalk2Java by Alexandre Bergel) Smalltalk to SQL (ROE by Avi Bryant) Smalltalk to AST nodes (Marcus Denker et al) HTML validator (Todd Blanchard) JSON to Smalltalk (Tony Garnock-Jones et al) (...contact me if you want to add your translator in the release, a facility to automatic installation of translators is provided) You can easily plug translators and the workspace will update the current contents dynamically inside a sticky-like dialog or a fixed pane, the updater interface was decoupled to make possible other kinds of widgets too, but this is a bit experimental. Downloads from: http://www.squeaksource.com/STicky.html Comments are welcome. Hernán

Database Support - ODBC
by flebber.crue＠gmail.com 21 Sep '09

21 Sep '09

Hi everyone I am new to Smalltalk. I am beginning a personal project a database application, I have looking for a language and environment I can be productive in long term and have full power in creating the database and access to query database, stored procedures from that language. I have been studying python/sqlachmeny, ruby/datamapper etc and various other combinations but haven't felt comfortable. Smalltalk environment looks promising, I want a tool to acheive my database project and have a tool to use for other projects rather than having to consistently learn new tools. However I am looking for some clarity on database support with Squeak and Smalltalk. I am assuming that squeak connects via ODBC, after reading the article here http://onsmalltalk.com/squeak-smalltalk-and-databases Is there a database that Squeak supports well. I am looking to use a low cost options since I am an individual. Had thought of using Postgresql or Oracle or MySQL. Is Squeak/Smalltalk a good choice for database development projects? not web development like seaside. Thanks Sayth

[ANN] Krestianstvo SDK - Smalltalk, Croquet, Seaside... programming on native spoken language (Russian)
by Nikolay Suslov 16 Sep '09

16 Sep '09

Hello! Introducing Krestianstvo SDK. Krestianstvo SDK is built on top of OpenCroquet SDK with preloaded packages (some of the list: Sophie XUL-CSS, Seaside, OMeta, and Krestianstvo itself). From now it will be entirely native spoken language based (Russian). The SDK is updated through change set's update stream<http://www.krestianstvo.ru/sdk/Krestianstvo/updates>and source code could be easily filed in/filed out containing unicode chars. The current developing version of the Krestianstvo SDK could be downloaded here <http://www.krestianstvo.ru/sdk/Krestianstvo1.0a.zip> (one-click image for Windows, Mac OS X, Linux). More information: http://nsuslovi.blogspot.com/2009/09/krestianstvo-sdk-smalltalk-croquet.html Official web site: http://www.krestianstvo.ru Discussion Group: http://groups.google.com/group/krestianstvo Thanks, Nikolay Suslov ----for Russian spoken--- Здравствуйте! Представляем вашему вниманию открытый проект Крестьянство SDK. Наконец-то, стало возможным программирование в SmallTalk, Croquet, Seaside на родном языке (Русском). Мы еще только в начале пути, но тем неменее уже доступен для скачивания базовый образ для основных платформ (Windows, Linux, Mac OS X). Крестьянство SDK построен на основе OpenCroquet SDK с предустановленными пакетами (некоторые из списка: Sophie XUL-CSS, Seaside, OMeta и Крестьянство). Отныне она будет разрабатываться полностью на родном языке (русский). Крестьянство обновляется путем потока изменений и исходный код может быть легко (загружаться в/ выгружаться из) образа приложения. Текущий вариант Крестьянство SDK можно загрузить здесь<http://www.krestianstvo.ru/sdk/Krestianstvo1.0a.zip>(однокликовый образ). Дополнительная информация: http://nsuslovi.blogspot.com/2009/09/krestianstvo-sdk-smalltalk-croquet.html Официальный сайт: http://www.krestianstvo.ru Группа для обсуждений: http://groups.google.com/group/krestianstvo С уважением, Николай Суслов

Recovering from a completely 'crashed' squeak image
by Andy Burnett 13 Sep '09

13 Sep '09

I ran the Update Software option on a new Seaside 2.8.4 one click image. After a long period of downloading and updating, I tried to save the image but got a DNU message about mouse overs. Anyway, in the end the image did save, but now when I restart Squeak I get a message saying "Squeak VM quit unexpectedly". I am not particularly worried about recovering the contents of this specific image - I had only been playing with it - but given that I am sure this will happen again at some point in my development life cycle, I would like to know the basic approach to recovering a usable image. What would people recommend. Cheers Andy
