|BUG] [FIX] centered text is not properly displayed in MVC [with proposal for a fix]
by Boris Gaertner 03 Jun '04

03 Jun '04

This bug report and fix is for Squeak 3.7 latest update: #5923 In an MVC environment, the first line of text is not properly centered. To see the problem, try this (in MVC): 1. Open a workspace 2. Type in some text into the first line 3. Select the typed text, call up to workspace menu and select more... -> set alignment... -> centered 4. The selection is now centered, but the text itself is not. 5. The problem does not appear when you type into the second line of the workspace. The problem is in DisplayScanner>> displayLines:in:clippedBy: The scanner begins type setting before its style atributes are fully initialized from the text to be displayed. I posted a similar bug fix at May 31, 2003, but the change set that I posted then is now outdated by change set #5632. The attached change set is a revised version which keeps the fix that was introduced with #5632 (It fixed a problem with the display of large italics) Greetings, Boris

[BUGFIX] Point>>reciprocal
by Trygve Reenskaug 03 Jun '04

03 Jun '04

I have a simple Morph structure: SlideRM(BorderedMorph) TransformMorphRM(TransformMorph) SlideInnerRM(PasteUpMorph) The Transform scale was aPoint. I got error when computing the inverse transform because Point does not understand reciprocal, see attached bug report. A simple fix could be a new method to Point: reciprocal " Answer a Point with coordinates that are the reciprocals of mine. " " Method was missing from release. " " 20040301 20:50:35 TRee(Squeak3.6-5429-tree07.38) " ^ x reciprocal @ y reciprocal. --Trygve -- Trygve Reenskaug mailto: trygver(a)ifi.uio.no Morgedalsvn. 5A http://heim.ifi.uio.no/~trygver N-0378 Oslo Tel: (+47) 22 49 57 27 Norway

[BUG] in Squeak Carbon VM ?
by Romain Robbes 03 Jun '04

03 Jun '04

Hi John, It seems that opening an image which is saved fullscreen on another machine does not open correctly if it is opened with the 3.7.2 beta 1 vm on a mac where the resolution is smaller. The image seems to be opened, but not displayed... Opening it with a 3.6 vm, and saving it with a correct fullscreen mode (ie same resolution) seems to solve the problem. Cheers Romain

by stéphane ducasse 03 Jun '04

While I started to prepare a new harvesting image on 5923, I clicked on the cross to close the default window. by accident I click on the squeak world window and did previous project, when I was again on the desktop I got some DNU I closed them and when I resized the squeak window then the flaps could not be displayed anymore (they were red with the yellow cross on them).

Re: Trouble installing Chuck
by stéphane ducasse 03 Jun '04

Hi lex I read your paper and tried to understand :) Long time ago I read the PhD of Agesen and the master of Garau, but I'm not sure I ever understood :) Anyway the paper is good and I will really have a look at Chuck. I think that we can build of lot of top of it. Now I have some simple questions: - Could we find a better characterisation of the goals to prune? I imagine that certain smalltalk constructs or highly polymorphic message sends could be prioritize to be pruned first. - Imagine a Smalltalk variant where we could annotate each AST node with type information, which may be wrong or absent. We could type check the code to make sure that there is a kind of coherence between the annotation but we could use this information for the inferencer. So do you think that this would be worth? - Alternately we could also analyze the name of the variable and extract some kind of type information that we could correlate with your findings. Stef

How to transmit user-defined object between client and server?
by kwiyi woo 03 Jun '04

03 Jun '04

Hello, I need to create a client and server application. I need to exchange information between client and server. I know I can use socketstream to transmit string between clent and server. But I need to exchange info which is not a string, but an user-defined object. I cannot find corresponding class in Squeak 3.6. The only thing I find might be helpful is class ArbitraryObjectSocket. But when I tried to initialize it by arbisocket := ArbitraryObjectSocket on: aSocket. it threw error message. Does anyone know how to exchange object and cast it in this situation? Thanks Kwiyi --------------------------------- Do you Yahoo!? Friends. Fun. Try the all-new Yahoo! Messenger

Re: [BUG] World menu via red button
by Chris Muller 03 Jun '04

03 Jun '04

I have a little bit more information. The problem appears to be *project*-specific. I created a new Morphic project and this problem as well as the SystemWindow widget problem both have disappeared! But only in that new project; as soon as I return to my original project, it's back. I've seen this before and remember creating new Morphic projects just to get rid of the problem. Something is happening, though, that is causing this behavior to manifest, I just don't know what yet.. Some debugging operation? Something with the RectangleMorphs and Connectors I have in this project? Not sure..
