Finding a squeak package

Fonts with non-standard sizes?
by Simon Guest 13 Dec '07

13 Dec '07

Hi, I've made a morph which contains some text, and the font size should depend on the size of the morph. However, if I just try to set the font using StrikeFont class>>familyName:pointSize: or TTCFont class>>family:size:, it only gives me fonts in certain predefined sizes. I know I can choose my own size using StrikeFont class>>fromUser, but what's the best way to do this in my code, non-interactively? Oh, and should I prefer TTCFont or StrikeFont, or does it not matter? And what should I use for the font family, for maximum portability? Can I assume BitstreamVeraSans is always available? What's better than assuming that? cheers, Simon

TestFailure: Assertion failed in first practice from Squeak by Example Hi Eric, Check your white space. There is a difference between 'oh no' and 'oh no '. While its hard for me to tell if this is your problem it is a common difficulty. And it will be easy for you to eliminate it as a possibility. Hth.

TestFailure: Assertion failed in first practice from Squeak by Example

Hell Squeakers, At home I went through the first half of the *Squeak by Example* book. The guided practice went without a hitch however, when I worked through the first practice of writing a simple String method at work, on a different image, I ran into this problem. Why am I receiving an 'Assertion failed' message? testShout self assert: ('oh no' shout = 'OH NO!') shout ^ self asUppercase , '!' TestFailure: Assertion failed Regards, Eric Eisaman

Switching between Browser views in the middle of (incomplete) edit - advice?
by itsme213 10 Dec '07

10 Dec '07

I frequently start to edit a method, then realize I need to look at or change something elsewhere. The method I was editing will not Accept as-is; and opening a new browser interrupts my flow. What is best practice here? Anything equivalent to a tabbed browser, or "hold this partly-edited code, I'll be right back" ? Sophie

Google Charts on Seaside
by Michael Davies 08 Dec '07

08 Dec '07

I was just putting together a simple component to help me use Google's mapping API, when I saw Lukas' blog post recording the exercise in remote pair-programming that he, Philippe Marshall and Adriaan van Os did to develop their version. I've just downloaded it and started playing and it looks great! Thanks to the dynamic trio for producing such a useful tool (and with such good timing)! Michael

Obsolete classes - I can find pointers to them, but how to get rid of them
by itsme213 08 Dec '07

08 Dec '07

PointerFinder reveals numerous pointers to obsolete classes. All of them seem to originate from something that appears (in the PointerFinder window) as either: #Refactoring -> Refactoring class or #EventManager -> EventManager class with lots of additional info. I have no idea how to even reach the handles that are holding onto these obsolete classes, them seem to be from Squeak code. Any pointers appreciated :-) Sophie

Morph speeds up stepping when grabbed
by kropki 07 Dec '07

07 Dec '07

Hi! I'm having some performance problems with morphs, I think. I have made two morphs: first is the owner of the second and the second one is doing stepping with as little timeStep, as possible (1?). Still it's too slow. When I click on the morph, the owner is being picked. While in the air, the step function for the submorph suddenly gets called very often and the animation is nice and fast. What's the reason for that? How can I modify the morphs, so that I get faster animation, when morphs aren't grabbed? Is it because, while in the air, one morph or another gets different stepTime or the step method is called in a different way? Or maybe some part of the code is not being run resulting in less overhead? Thanks for your help :) cheers, kropki -- View this message in context: http://www.nabble.com/Morph-speeds-up-stepping-when-grabbed-tf4961762.html#… Sent from the Squeak - Beginners mailing list archive at Nabble.com.

Text with Link
by Hilaire Fernandes 07 Dec '07

07 Dec '07

How can I append a link to a text in a text morph? I am trying without success: | t m | m := TextMorphPlus new openInWorld. t := Text string: 'hello ' attribute: (TextColor red). t append: (Text string: ' TOTO' attribute: (TextLink scanFrom: (ReadStream on: 'LMorph new;'))). But really I don't understand the way to use TextLink Hilaire

comint from VAST and being HU
by RK 07 Dec '07

07 Dec '07

Hello! I'm Robert and I'm developing in Smalltalk for 10 years by now. I'm looking for and alternative smalltalk and I would like to port some existing applications from VisualAge. I started to read some Squeak documentation, and it seems to be great (both the documentation and Squeak itself!). However, I have a very basic question I can't figure out, maybe because the answer is trivial. I'm Hungarian and our software code and applications conatin national character strings. This is quite normal :) On Linux I have this setting: LANG=hu_HU.UTF-8 Squek starts with no problem, and keyboard is working well, all characters are on its right place, so the Hungarian keyboard and settings are working well, but there are two Hungarian specials for which nothing appears. These are o with double acute and u with double acute (o" u" O" U" - just imagine the double acute above the o-s and u-s) both regular and capital. Simply nothing is displayed. It usually mens that there is no glyph for those in the character set applied - but I'm not sure. On windows these ar in Central European sets (Win1250 or ISO-8859-2), and naturally, all unicode sets contain these... Before I start any migration tests I must be know the answers about this very little but very essential problem. thanks for any help Robert Idén utoljára Könyvszerda! 30% kedvezménnyel 6 kiadó 1800 féle könyve!
