[STYLE BUG] No PWM 1 and 2
by Andrew C. Greenberg 04 Feb '01

04 Feb '01

It looks pretty unpolished to have PWM Numbered 3 though 8. Perhaps should either renumber or add a few PWMs?

Absolute latest Windows VM ?
by Eric Arseneau 04 Feb '01

04 Feb '01

If I go to the page on the squeak.org Swiki http://minnow.cc.gatech.edu/squeak/308 (DownloadForWindows) and I follow the link ftp://ftp.cs.uni-magdeburg.de/pub/Smalltalk/free/squeak/win32/ I can't find any 2.9 VM in any of the folders, or anything very recent. I'm sure this question has been asked many times, but I just did a bunch of searching on the message archives and could not find what I needed. Any help would be appreciated, tx

Other users should fetch the first three files and decompress them with Squeak's decompression available in the FileList.

Many thanks for your persistent and cheerful support. Bob's SuperSwiki is not in the FileList anymore. I tried to add it my self but keep getting server timeouts etc. What is the magic ? Karl

[BUG] Confused about font sizes
by David N. Smith (IBM) 04 Feb '01

04 Feb '01

I've been looking at font sizes a bit closer rather than considering them magic; guess the right number and you get the size you want. I wrote this bit of code to put up TextMorphs with font sizes of 10 to 27: (27 to: 10 by: -1) do: [ :n | TextMorph new contents: (Text string: 'Font size = ', n printString attributes: {TextEmphasis normal}); topLeft: 10@(n*20+10); fontName: 'NewYork' size: n; openInWorld ] It produces the smallest size for the range 10-14, the next biggest for the range 15-20, the next biggest for the range 21-25, and the largest for values starting at 26: 10-14, 15-20, 21-25, 26-up The menu available in virtually all text areas uses the sizes 12, 15, 18, 24. Note that 15 and 18 are in the same range and should be the same size but aren't. There are four strike fonts for New York: a StrikeFont(NewYork10 12) a StrikeFont(NewYork12 15) a StrikeFont(NewYork18 21) a StrikeFont(NewYork24 26) where the first number seems to be the height of the pixels and the second is the base line spacing. This would suggest using either 10, 12, 18, and 24 for the point sizes, OR using 12, 15, 21 and 26. Comparing them with a different implementation of New York in Apple Works it looks like 10 and 12 are about the same size both places. The numbers in the menu (12, 15, 18, 24) seem to be the interline spacing for two sizes, and the base font size for two others. Is this right? I'm confused, though I have figured out how the secret behind the magic numbers I have to use to get TextMorphs to produce the four sizes. What are the right sizes, and why aren't they the same everywhere? Dave -- _______________________________ David N.

Remove class Flipper
by Karl Ramberg 04 Feb '01

04 Feb '01

Morphic kernel category contains a class named Flipper, with no methodes, variables etc. I think this could be safely removed Karl

[enh] drag and drop capability for filelist
by frazier＠one.net 04 Feb '01

04 Feb '01

This change set adds the capability to perform simple file copies via drag and drop both within a single FileList and between two independent FileLists. For this initial cut of software, only file copies are supported. There's a provision for prompting the user for a move operation. Also, no real action is provided yet for folder copies. The operation is supported; the method does nothing. This was tested on Squeak v2.9a update #3324. The attached file should be a compressed change set. - Steve Wessels

RE: [BUG]World has a one pixel green frame.
by Raab, Andreas 03 Feb '01

Funny you should mention this; below is a message from Bob on the issue. The solution is as trivial as "World borderWidth: 0" :-) Oh, and what constitutes this as a [BUG]?! ;-) Cheers, - Andreas > -----Forwarded Message----- > From: Bob Arning [mailto:arning@charm.net] > Sent: Friday, February 02, 2001 6:52 PM > To: Alan.Kay(a)disney.com; Dan.Ingalls(a)disney.com; > Ted.Kaehler(a)disney.com; > Raab, Andreas; John.Maloney(a)disney.com; Rose, Kim; > Scott.Wallace(a)disney.com; arning(a)charm.net; Rueger, Michael > Subject: WorldDrawCleanup-ar > > > Andreas, > > It's interesting to see your changes in WorldDrawCleanup-ar. > About a year ago I was wrestling with an oddity wrt screen > redraws.

This happens for me when I have a Workspace open that has a binding of a variable to a block context. That is, if I have the following in a Workspace: a _ [ :val | val + 2 ]. and DoIt, then try to save the project, I get this error. -- Ned Konz currently: Stanwood, WA email: ned(a)bike-nomad.com homepage: http://bike-nomad.com
