Re: [sqh] How close is SmallTalk Express to Squeak syntactically?
by Bruce O'Neel 24 Nov '98

Hi, I've also used On To Smalltalk by PHW and found it good. It was pretty much perfect up to the files chapter, which I didn't really do, and then the GUI chapter seemed wrong. I am, oh so slowly, learning how to get GUIs to come up. cheers bruce Jake Hamby <jehamby(a)lightside.com> wrote: > > Laurence Rozier wrote: > > > > Asymptotically Approaching Harmony wrote: > > > > > Hi folks; > > > > > > After doing an Amazon search I just found a book called _On to > > > Smalltalk_ by Patrick Henry Winston - I really like his style, _On to > > > Java_ is one of my fave Java books by far. > > I ordered this book from Amazon.com and am also extremely impressed with > it.

Changeset Problems
by Gerardo Richarte 24 Nov '98

24 Nov '98

While building the package for MorphicWrappers, we found a problem that we cannot reproduce right now, but I can describe: We had two classes, ClassWrapper and BitmappedWrapper, we renamed them to ClassMorphicWrapper and BitmappedMorphicWrapper, we made fileOut of the change set, and when we made fileIn from a fresh image, those renamed classes where missing. I'm not sure if it has something to do with renaming the classes (I tried to reproduce this behaviour, but I culdn't). What I do have is a .ZIP (2.5M) file with a .image and a ..changes that will have this problem. Problematic Bye! Richie++

System Windows problems
by Gerardo Richarte 23 Nov '98

23 Nov '98

While condig latest version of MorphicWrappers (soon available), we found a problem: After setting allowSysWindowsEmbedding in Preferences, when you drag an opened (not collapsed) system windows to the TrashCan, not only two error pops up, but the StackTrace is dumped. The problems are in SystemWindows' #passivate and #activate methods, sorry for only posting the problem and not the solution... Problematic Bye! Richie++

Try this: TextStyle changeDefaultFontSizeBy: 1 I filed out the code that does this, so you can browse TextStyle for more info.

It then initializes most references in the system as well, although most windows will have to beclosed and reopened to get the effect." | allFonts | allFonts _ TextStyle default fontArray asSortedCollection: [:a :b | a height < b height].

[sqh] How close is SmallTalk Express to Squeak syntactically?
by Asymptotically Approaching Harmony 23 Nov '98

23 Nov '98

Hi folks; After doing an Amazon search I just found a book called _On to Smalltalk_ by Patrick Henry Winston - I really like his style, _On to Java_ is one of my fave Java books by far. So, how close is Smalltalk Express, the dialect he uses in the book, to Squeak? Will I hopelessly scramble myself trying to learn using his book and Squeak instead of ST Express? Thanks, -Chris P.

I started Squeak 2.2 on NT, and found the fonts too small to read comfortably. What should I do?

Here are some things on the AOLserver feature list that I would rather use than build myself: * Web-based Administration * Fast and efficient handling of simultaneous connections through a combination of multi-threading, in-memory caching, and single-threaded asynchronous I/O. * Multihomed Architecture * Secure Sockets Layer * Hierarchical Access Control - Restrict access to all or part of your Web through lists of users, groups, and/or client address * FTP Server - Uses the same access control as the HTTP server and lets you write scripts that run every time pages are uploaded or downloaded * SHTML server-side includes * etc. -- Patrick Logan mailto:patrickl@gemstone.com Voice 503-533-3365 Fax 503-629-8556 Gemstone Systems, Inc http://www.gemstone.com Now they have Isomighty Apomorphin Power LaGrangers.

I love PHW as well. OTS is okay, but there are a few reallly good web tutorials that I prefer to his text. It was good, and for $15 you can't lose, but not ideal. > After doing an Amazon search I just found a book called _On to > Smalltalk_ by Patrick Henry Winston - I really like his style, _On to > Java_ is one of my fave Java books by far. > > So, how close is Smalltalk Express, the dialect he uses in the book, > to Squeak? > > Will I hopelessly scramble myself trying to learn using his book and > Squeak instead of ST Express? > > Thanks, > > -Chris P. > (Aspiring Squeaker) > > ____________________________________________________________________ > |Chris Patti|ICQ#16333120|feoh(a)cosmic.com|Home > #:(617)625-3194|JAPH| > |"The best way to predict the future is to invent it" - Alan Kay | > >
