Squeak Foundation Board 2007 Candidates

2007-02-19T07:20:57Z

Hello everyone,

Our deadline for announcing your candidacy to the Squeak Foundation Board
has passed, which means we have a final list of 12 candidates. They are:

Cees de Groot
Tim Rowledge
Bert Freudenberg
Craig Latta
Stéphane Ducasse
Giovanni Corriga
Keith Hodges
Andrew P. Black
Todd Blanchard
Yoshiki Ohshima
Tansel Ersavas
Brad Fuller

We have a short time to find out more about these candidates before the
election. I will be sending the same questions to each candidate and will
publish a final article on http://weeklysqueak.wordpress.com . I will post
a link here when the article is finished. The answers will be published in
the order that I receive them back. Which could mean you should start
reading at the bottom!

In the mean time I encourage people to support your favorite candidate!
Please post a recommendation for your favorite candidate, include details
about that candidate that people may not know. It is sometimes difficult
for people to talk about themselves so I encourage you to help. I say
support your favorite candidate and not a group of candidates for a reason.
Many people support all the candidates and feel that if they post something
about someone they need to post something about everyone. So let's take
posts about someone as a positive thing and not a vote against others. Help
us learn about the people running by sharing what you know about them.

If you support a foundation platform now is a good time for you to tell us
that. Submit your ideas and let candidates comment about your platform
suggestions on-list. The more we can make this an open discussion the
better.

Remember voting starts on March 3rd, 2007.

Thank you everyone for participating!

This version of Tweak is not actively developed or maintained any more.

Squeak Board 2007 Elections

2007-02-10T09:59:45Z

Hi All,

I received another question about running for the board. As a reminder anyone that wants to run for the board needs to announce to squeak-dev by February 18, 2007. All you need to do is send an email to squeak-dev (squeak-dev@...) stating that you are running. We would like you to include why you are running, what your experience is and what you would like to work on if elected.

We currently have 4 candidates for 7 positions: Cees, Tim, Craig, and Bert.

It’s going to be a very quick election if we do not get more candidates! Please consider serving your community by running for the board.

Thanks,

Ron Teitelbaum

Candidate Deadline Feb 18th 2007

2007-02-04T17:36:30Z

All,

I had someone ask me this question so I thought I'd remind everyone about
our candidate deadline.
http://weeklysqueak.wordpress.com/2007/02/01/2007-squeak-board-elections-ann
ounced/

If you are planning on running for the board you need to announce that fact
to this list (squeak-dev) by Feb 18th 2007.
http://lists.squeakfoundation.org/mailman/listinfo/squeak-dev

>From memory, I know that Craig, Tim, and Bert are running again. I do not
know about Cees, Yoshiki, and Marcus.

I could be wrong about who has announced and who has not. If so please
correct me.

Now is the time to encourage people to run.

Also remember you will need an account on Squeak People
http://people.squeakfoundation.org/ with a certification of at least
apprentice to vote. If you have questions please feel free to ask the list
or send me an email.

Thank you for your participation,

Re: Word wrapping in Tweak

2006-10-20T08:49:40Z

I have this version of
MultiCharacterScanner>>scanCharactersFrom:to:in:rightX:stopConditions:ke
rn: in my image:

ar 4/12/2005 19:53 · scanning · 2 implementors · in change sets:
5994-004-systemMod 6651ExternalCleanup 6662WideNames

But word wrapping is still occurring in the middle of words in my image.

I found differences between MultiCompositionScanner and
CompositionScanner in crossedX, notably that breakAtSpace is set to
false in setFont, causing crossedX to drop to the clause at the
bottom commented:

"It wasn't a space, but anyway this is where we break the line."

So, as shipped the class will always break the line anywhere. But
setting breakAtSpace true did not seem to fix to problem. Also, i
tried initializing MultiCharacterScanner:

(MultiCharacterScanner(class)>>initialize

with no effect. I can see the wrapping being broken in the first two
windows you open when Tweak starts up as downloaded straight off impara.

this method should be from '05 with the main difference being that the

Yes, it's a reasonable workaround. I was hoping that I could reply to
this pointing you to the new and improved island scheme that makes these
hacks unnecessary. Unfortunately, this will take some more time so for
the time being just go with that version.

Word wrapping in Tweak

2006-10-19T15:10:02Z

What's the story with MultiCompositionScanner? The version I have in
my (not too recently updated) Tweak image is used by CTextComposer as
the scanner, and is the reason word wrapping seems broken in Tweak.

I regressed to CompositionScanner, which got word wrapping back at
the cost of multi-lingual compatibility (?).

I was just wondering if MultiCompositionScanner had progressed beyond
12/2002 (timestamps seen in there).

Tweak Bootstrap Script Scheduleing

2006-10-10T05:51:44Z

Hi,

When bootstraping a CWorldPlayer from Morphic the ScriptScheduler is
added in initialize if nil. But already registered Scripts like a
onDragDrop: in a CWorldWorld subclass have no scheduler and get
suspended when triggered...

Is the solution to patch the scheduler into the script in this case
(like Bert Freudenberg proposed) ok?

CWorldPlayer>>initialize
"Bootstrap a new world"
super initialize.
scheduler ifNil:[
scheduler := ScriptScheduler new.
"set the context for any newly spawned scripts"
scheduler run.
self myScripts do: [:eachScript |
eachScript setScheduler: scheduler.
]
].

No Tweak onMouseDown with control-key (Windows)

2006-09-12T16:06:40Z

Seems like the event is getting swallowed somewhere. I see it as
expected, with the expected modifier key on the Mac. On Windows, the
event isn't getting fired when the control-key is held down.

Re: did anybody use CFileSaveDialog?

2006-09-08T15:04:20Z

I made similar changes for Hermes to allow saving attachments from email messages or attaching files to email messages. I also created a class variable that remembers the last directory location so that sequential attachments (of files to email messages) goes a little faster.

I re-arranged the Save dialog to put the name field more prominently at the top of the dialog, and refined button enabling dynamics so the Save button is not available when not appropriate.

Lastly, I enabled the Save dialog to optionally be provided a filename at instantiation to allow a user to accept the MIME header filenames that might appear in attachment meta-data.

I did all this as subclassed redefinitions of a few features for CFileOpenDialog, CFileSaveDialog and CFileSaveDialogCostume. Code is on SqueakSource, or I can supply changesets if you care to see.

overriding compilerClass in Metaclass

2006-09-06T08:35:15Z

Hi,

I've run into a Problem with changing the compiler of a class in a Tweak
System. (JavaScriptCompiler from Marcus Denkers Babel)

Tweak overiders

Metaclass>>compilerClass
^thisClass compilerClass

but this has the effect, that you can't define a new compiler class on
the class side, because the system uses the new compiler for the class
and the instance sides.

Extending CCollection/CMultiColumnList for multiple selections

2006-08-29T09:44:08Z

I'm about to extend CCollection/CMultiColumnList to support the
notion of a multiple selection in the UI.

I thought I'd check to see if someone is already doing/has done this.

Ah. In this case use the #accept event for an input field. This will be
signaled if the user accepts the input manually (e.g., upon hitting
enter/return).

Re: Handling ui feedback loops

2006-08-17T22:24:41Z

I suppose, I have a multiple selections, so multiple models to check
against, so the loop could go through twice.

I'd rather get a differtent signal when the user made an edit,
opposed to any old value change. In other words, anything else
modifying the UI to get a model change is a broken pattern. I really
only want to know when the field changes due to a direct user action.

> Whats the proper pattern for this use of tweak fields and input fields?

You'll have to guard manually, e.g., instead of either

MyInputField>>onModelValueChanged
<on: valueChanged in: model>
self value := model value asString.

MyInputField>>onValueChanged
<on: valueChanged>
model value := Number readFrom: self value.

(which may loop) use either one of:

MyInputField>>onModelValueChanged
<on: valueChanged in: model>
newValue := model value asString.
newValue = value ifFalse:[
self value := newValue.
].

MyInputField>>onValueChanged
<on: valueChanged>
newValue := Number readFrom: self value.
newValue = model value ifFalse:[
model value := newValue.
].

Handling ui feedback loops

2006-08-17T19:33:17Z

I have a input field and when I change the value of the tweak field,
its mirrored into the field. I also use this field as a input field,
so I want to know when the value changed, and update my model.
Problem is, I set the field, I get a changed event, I convert the
field string gto a number, set my model, which updates the field, and
around and around I go.

propertyValueAt: key put: newValue with: changeEvent
"Store the value of my property at key"
| oldValue |
myProperties ifNil:[myProperties := IdentityDictionary new].
oldValue := myProperties atProperty: key put: newValue.
oldValue == newValue ifTrue:[^newValue].
self signalChanged: changeEvent from: oldValue to: newValue.
^newValue

Does ==, which fails because '123' == (123 asString) fails.

WHats the proper pattern for this use of tweak fields and input fields?

Tweak window order

2006-07-26T08:36:07Z

Can somebody tell me the correct runes for managing window order?

I have UIs that use a variety of player/costume arrangements, all
using CWindows with the title frame, and all seem happily reorder
themselves upon mouseDown.

I get into trouble when I close, open or "reopen" them (reopen being
repeating a menu call that opens a single-instance UI or requests
activation of an already open instance).

I've been able to track down the close, closeRequest, beTopWIndow
methods, as well as sending around activate signals. What I seem to
be missing is a reliable way to force a window to the front of the
stack; it seems that sending #activate just gets me the correct
appearance in the window frame (without actually bringing the window
forward).

Trying to understand CWindowManager has given me a bad headache!

Here's the promised fix:

http://bugs.impara.de/view.php?id=4241

The problem can be seen here:

o := CObject new.
o startScript: [
duringMy := o handlesEvent: #myEvent.
duringOther := o handlesEvent: #otherEvent.
o signal: #myEvent].
beforeMy := o handlesEvent: #myEvent.
beforeOther := o handlesEvent: #otherEvent.
o waitUntilAnyOf: {
o. #myEvent.
o. #otherEvent.}.
afterMy := o handlesEvent: #myEvent.
afterOther := o handlesEvent: #otherEvent.
{#myEvent->beforeMy -> duringMy -> afterMy.
#otherEvent->beforeOther -> duringOther -> afterOther}.

This prints

#(#myEvent->false->true->false
#otherEvent->false->true->true)

before and

#(#myEvent->false->true->false
#otherEvent->false->true->false)

after my fix.

Double Click fix

2006-07-12T09:38:25Z

Hi all,

attached a fix for the click-double click problem.

You need to wait for another fix (cleanup for multiple event waits) Bert
is working on right now for this to work reliably.
Unless you are willing to wait for a full garbage collect between mouse
clicks ;-)

You're right, I'll take this back. The picture makes perfect sense.

That's bug #1039, you currently get the double-click before the click.

Actually, no. That would mean you could get a click event only after
the double-click timeout. The UI would feel very sluggish that way.
What UIs usually do is that click selects the item and the following
double-click performs some action on it.

See the GIFs attached to

Also, see the bug report itself and its related reports. Assigned to
me for ages, I know :( Hasn't been a show-stopper until now ...

I'll wait to see what Andreas finds, and then have a look myself, if
still necessary.
