[BUG] BTree>>removeKey:
by Joshua Gargus 18 Jan '05

18 Jan '05

Hi, The following code results in an error: | tree | tree := BTree new. 1 to: 15 do: [:i | tree at: i put: i]. 1 to: 15 do: [:i | tree removeKey: i] I first discovered it with Collections-BTree-avi.38 under Jasmine, and verified that it also happens with Collections-BTree-avi.42 under Squeak-3.7-5989-full. Thanks, Josh

How to update the appearance of a morph in mid-method?
by Jim Rosenberg 08 Jan '05

08 Jan '05

I have a morph that I want to have "flash" its border color in blue for a couple of seconds and then restore itself to its prior state. I know how to change the border color. I know how to achieve a delay. Everything works if I "do something" to interrupt the method at the point of the color change. But if I let it run, the display seems to be caching the state of the display in such a way that I never see the color change. After the color change I'm trying sending the morph layoutChanged, sending its owner layoutChanged, even going so far as to try Project current world restoreDisplay -- nothing works. Sigh. There has to be a simple way to do this. How do you tell a morph to show itself "right now" in its current condition -- in mid-method? -Thanks, Jim --- Jim Rosenberg http://www.well.com/user/jer/ WELL: jer Internet: jr(a)amanue.com

[BUG][FIX] Global Flaps Fix
by Hernan Tylim 07 Jan '05

07 Jan '05

Tried on the latest 3.8 gamma and 3.9 alpha. Here is my fix for dealing with the global flaps disappearance. BTW, in 3.8 the font used for the thumbnail labels doesn't render well in small font sizes. This fix is also registered on Mantis.

"Change Set: GlobalFlapsFix-hpt Date: 28 December 2004 Author: Hernan Tylim This is a .cs with only a postscript that will reinstate the global flaps on Squeak 3.8 (and 3.9).

I have actually asked about this on a number of occasions but the interest has been low so far. But perhaps the sheer number of packages now has increased the interest. Tell you what - if you take the time to come up with a proposal I will gladly make the changes (requires admin rights). Also, the last modified should indeed be visible - especially since the model has that info, though I am not sure it is completely correct at the moment. regards, Göran *********************************************************************************** This transmission contains information which may be legally privileged, proprietary in nature, or otherwise protected by law from disclosure, and is intended only for the use of the addressee(s) named above.

Best way to update...
by Mark Mayfield 31 Dec '04

31 Dec '04

What is the best way to update an image from major release to major release? For example, what will be the best way to update from 3.7 to 3.8 when 3.8 goes final? In the past I've filed out my projects and read them back in one by one into the the new release. This is slow and tedious, but it works. Thanks, Mark

StandardFileStream not closing files immediately
by Yar Hwee Boon 31 Dec '04

31 Dec '04

I'm having problems deleting a file after closing its file stream and it seems to be described in this thread http://lists.squeakfoundation.org/pipermail/squeak-dev/2004-February/074560…. A gc seems to fix it. Is there a way to explicitly close it *immediately*? Thanks. -- Regards HweeBoon MotionObj

A question of ethics
by Trygve Reenskaug 31 Dec '04

31 Dec '04

Hi all (and especially Ned), I am working on a second release of my reverse engineering toolset, BabySRE. One problem is that I am using Connectors version 1.9. SRE doesn't work with the new version, 2.0. I have three alternatives: 1) Study Connectors 2.0 and adapt BabySRE to it. 2) Write a new program that satisfies my modest diagramming needs 3) Rename/modify the Connectors 1.9 classes so that they can coexist with Connectors 2.0, strip out what I don't need, modify the rest as required, and package the result together with BabySRE. I don't want to do 1) because I only need a small part of Connectors and because I will have to keep adpting to a moving target. I don't like to do 2) because it seems a waste of time. I prefer 3) because it gives an independent SRE package with a minimum of hassle for its users, with a single maintainer (me), and with a minimum of work. The question is: Is it ethical/unethical in the Squeak community to copy/modify somebody else's classes (with class comments spelling out that I have done so, of course)???
