Can Squeak display chinese?
by Simon Chan 24 Oct '08

24 Oct '08

Hi all, I am a total beginner, just started few days. I just found smalltalk has the nicest development environment I have even seen, especially the image persistent. Persistent has always been a problem to me, I always wanted to create some personal applications, but persistent problem has always stop me, I just hate using relational database, creating sequences, dropping and adding fields, during the development it's a very painful experience. The only problem I am having is that it cannot display chinese characters, I really want to develop something simple wihout rdb. How do I make Squeak displaying chinese characters, all chinese characters are shown as ? Can anyone help me, thx a lot!

Re: [Newbies] Applets in Squeak

hiya all! i've created a link to my project. the thing is: it opens but looks as if it's been scrunched up and black margins, above and below, appear. i've noticed that the "display mode" menu enables "scale to fit" option and i think that's the reason why the margins appear. is there any way to enable "no scaling" instead "scale to fit" everytime the browser opens a project? ta very much! -- View this message in context: http://www.nabble.com/Applets-in-Squeak-tp20013438p20016166.html Sent from the Squeak - Beginners mailing list archive at Nabble.com.

squeak.org unavailable?
by rickm45 23 Oct '08

23 Oct '08

I have been trying to access http://www.squeak.org over the past week and always get "10061 - Connection refused". Firefox or IE. I can access news.squeak.org though but not the others, ie, map.squeak.org, etc. I've tried from work and home with the same result. http://downforeveryoneorjustme.com/squeak.org tells me it doesn't recognize squeak.org. Am I the only one having a problem? I'm trying to get to the download page among other things. Thanks for any info, rickm -- View this message in context: http://www.nabble.com/squeak.org-unavailable--tp20091445p20091445.html Sent from the Squeak - Beginners mailing list archive at Nabble.com.

I, too, cannot connect to Squeak.org or its associated websites. This has been the case for about 5 days now. A message from the maintainers telling us the status would be helpful.

Dialect class
by xyz 42 22 Oct '08

22 Oct '08

Hello! I am missing the Dialect class (I typed Dialect in workspace and said browse). Is this part of Squeak or is this part of some package? If it is part of some package, how can I find out which package? I am using the web image (3.10.2) here http://damien.cassou.free.fr/squeak-dev.html. TIA.

Morphic widgets
by Vijay Mathew 22 Oct '08

22 Oct '08

Hi, I would like to know how I can design this simple credentials form in Squeak. There will be a text field, one password field and two buttons. Is there a Morphic widgets library? Do I have to implement my own widgets? Thanks, -- Vijay

Problem filing out change set
by Chris Kermiet 18 Oct '08

18 Oct '08

Hi, Folks -- I'm new to this list. I'm learning squeak by by creating some artsy objects which create designs according to mathematical algorithms (based on Schillinger's Mathematical Basis of the Arts). It seemed like a good idea to add the constant Phi to the Float class to keep from recalculating it. (Phi is the Golden Ratio -- the limit ratio of the Fibonacci series.) Now, when I try to file out my change set, I get the error message: /"An instance variable was added to class Float and it is not copied in the method veryDeepCopyWith: Please rewrite it to handle all instance variables. See DeepCopier class comment."/ When I look at the DeepCopier class comment, I have no clue what I'm supposed to do. Does this new instance variable need to be copied somewhere? When the class Float was recompiled, shouldn't that have added the new class variable to the appropriate dictionary? The instance variable is referenced from the class side: phi "Answer the constant, Phi." ^ Phi in exactly the same way as pi or any of the other constants initialized in the Float class. Does it need to be copied somewhere else? In addition, this error message seems unnecessarily vague. Please rewrite "it" -- what does "it" refer to? The instance variable (phi), the Float class, the veryDeepCopyWith: method? Or the class variable (Phi)? When I look carefully at all of these, none of them look like they should need rewriting. Unless I should do (just a guess): Float veryDeepCopyWith: phi in a workspace. But I'd like to know why before I try it. Anyone have any ideas on this? Any help would be appreciated. Thanks. --Chris Kermiet

Hello, I'm testing etoys-dev-4.0, with etoysV4.sources and a new VM linux version, If I set the pangoRenderer Preference to Off and I change the language (french, german...)... no problem, but if I want spanish (like my machine) automatically pangoRenderer put On. In this situation, even if I set again pangoRenderer Preference to Off when I save the image automatically pangoRenderer put On again. I do not know reallly if this process is "for my machine only" regards
