Hi, does anyone work on Squeak stuff for system biology (Pi Calculus simulation systems, for example), silicon cell (for example like e- cell ) or other bioinformatics stuff (statistic datamining)? Regards Hans

You put in slot or main memory? What image? I did can tried squeak in my poquet because is slower and very big. Give me some issues, send me the image, or something please :P About the Alt+Key problem, are you tried show the pocketpc keyboard, press ALT and TAP? Cheers.

Ok, I will think about doing that. There are two blocks involved here though as there is a level of indirection. The first one above calls a method which looks up #RESETHW in the server dictionary to get another block which calls the target method. In this simple case the target method is also in this component but in most cases it is on one or more of the connected components, the other end of the connector link (i.e. when the link is connected the maps get exchanged and in this case of course self is the target). Do you think I'm flogging a dead horse here? I will fabricate a simple case with message send and see if that works.

RE: Persisting 'applications'

Chris Sorry, but I am going to have to ask for help again. I can now manage the lifetimes in the database and image. Although it took me a while to get the process repeatable and figure out where all the references were. However, it now works and connectors stay connected. Unfortunately now that I am really retrieving from the database a retrieved app does not work. At least none of the UI events work, but then I am using dynamic techniques to hook everything together. I have a taken a simple case which is one composite component with one button on it. The button fires a block which references self in this case. However, self appears to be nil. This is where it fails. DoIt | t1 t2 t3 t4 t5 | super initialize. t2 := ImageMorph new. t3 := GraphicPath , 'sdr1000.gif'. t2 setNewImageFrom: (Form fromFileNamed: t3). t1 := SDRButton newWithParams: 'Reset' actionSelector: #(#RESETHW ) actionTarget: [:t6 | self buttonAction: t6]. self borderWidth: 2. self borderColor: #complexFramed. self color: Color gray. self addMorph: t2. self addMorph: t1. t4 := t2 extent. t5 := t1 extent. self extent: t4 x + t5 x + 8 @ (t4 y + 8) MessageNotUnderstood Undefined object buttonAction. This method called DoIt seems to be my Initialize method with the variables replaced with generated names. GraphicPath refers to a pool dictionary which it also can't resolve, don't know if that's relevant. I have attached the file. The button is set up in the SDR1000Morph Initialize. It is called through the block in the dictionary set up by SDR1000Controller createServerInterfaceMap at #RESETHW. I know this is a lot to ask. If it's not obvious what I need to do please don't labour over it.

[RFC] Changesets and MC cause each other confusion and woes.
by Peace Jerome 24 Feb '06

24 Feb '06

I'm looking for ideas, answers, and solutions for the increasingly important problem of choosing and managing catagories so that both change sets and MC can be used to develop squeak. I've set a seed for the issue on Mantis at: 3074: Filing out a change set will reorganize class catagories causing MC confusion and woes. http://bugs.impara.de/view.php?id=3074 Discussion here and in the Mantis issue are requested.

Election almost over!
by Brent Vukmer 24 Feb '06

24 Feb '06

Hey folks. I got emails from a couple of folks today asking for re-sends for their voter invitation. Since I don't have webmail access during the day, I was only able to act on those requests now (10 minutes before the voting deadline). I'm going to extend the voting deadline by three hours in an attempt to give those folks time to vote. The deadline will now be Friday February 24th 0300 UTC. I hope that doesn't ruffle anyone's feathers. I would rather err on the side of being flexible this first time around. This is a wonderful opportunity for all you folks who haven't voted yet! Get to it! :) The deadline is now Friday February 24th 0300 UTC. Total authorized voters: 347 Actual votes cast so far: 154

Alt-key on Pocket PC
by Michael Patrick 24 Feb '06

24 Feb '06

I am trying to use Squeak on an iPaq 4150. The software runs fine but I can't find what is used to simulate the Alt-key. I apologize if this is the wrong list.

So this work around is not a good idea. Have to revert to a <pragma> thing... 3.9 image added the framework for such things i think. Are there teams working on it and previews of code ? Nicolas
