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

I found that there are some Float-Subclasses: FloatD FloatE FloatQ How can I use them and what are they good for? I do not understand the use of LargeZeroInteger as well. Thanks for possible tutoring! Regards B. Blochl

squeak quickreference?
by bb 29 Jun '11

I found a squeak quickreference as pdf on different links in www. As source is given This document is in the Squeak Documentation Archive at: http://docs.squeakspace.com/quickreference But this link is obviously dead? Under which license may I use and distribute the document? I look for the "original" because in none of the different documents from the different links is given any copyright? So the license of that document remains a mystery. is there anyone able to help? Regards B. Blochl

asInteger bug?
by bb 27 Jun '11

27 Jun '11

There I found a problem with asInteger: According to the x3j20 ansi standard Float>>asInteger and Double>>asInteger should be equivalent to sending rounded. You can download the final draft revision for free: wiki.squeak.org/squeak/uploads/172/standard_v1_9-indexed.pdf. I tried that in squeak 4.2: 1.11 asInteger 1 1.99 asInteger 1 1.11 rounded 1 1.99 rounded 2 Astonishing is the result as well: (0.6 / 0.2) asInteger 2 That seems to be the conversion Problem of odd decimals to binary, well known from most of the programming languages. Here another experiment: 2.999999999999 asInteger 2 2.999999999999 rounded 3 2.999999999999999 asInteger 2 2.9999999999999999 asInteger 3 Is squeak/Smalltalk not x3j20 ansi standard compliable? Regards B. Blochl

I don't get it
by Erlis Vidal 27 Jun '11

Hi guys, I was reading recently Jim Coplien ideas about DCI and I was surprised with the following statement: *"The Smalltalk people, when they put together Smalltalk originally the computational model was exactly right, in terms of thinking in terms of objects. And then they screwed it up with the language. The language is so class focused! Most languages that we’re saddled with today had made this error." * you can find it here: http://blog.redtexture.net/2010/06/01/coplien-on-dci-mvc/ Does someone knows what Jim is criticizing? In which sense the computational model was screwed by the language? I see smalltalk as a language that express very well the intended computational model behind. But that's just me, maybe some of you could help me to understand Jim's point. Thanks Erlis

autocompletion squeak 4.2
by bb 23 Jun '11

23 Jun '11

I actually installed squeak 4.2 and missed the autocompletion. To try Ocompletion from Levente Uzonyi out, just evaluate the following script in your image: Installer squeaksource project: 'RoelTyper'; install: 'RoelTyper-FredericPluquet.82'; project: 'OCompletion'; install: 'OcompletionSqueakCompatibility-ul.1'; install: 'Ocompletion-ul.67'. May be that will help other users on autocompletion deprivation. For deatails please consult http://news.squeak.org/2010/10/07/tab-completion-returns-to-squeak/. Regards BB
