[Pharo-project] Best way for change a window style
by nullPointer Jan. 5, 2011

Jan. 5, 2011

For a TIP example I want implement in Pharo the steps for build a GUI like that: http://forum.world.st/file/n3032341/eBox.png The main problem for me is the window style. I understand one way for change the style of windows is create my own UITheme subclass; but exists some alternative way for generate a new style for windows? a generic window: I only want a one panel with the three buttons for close, minimize and maximize, and the rounded corners, much more rebranded in top corners than bottom, with the default behavior of window: draggable for the Desktop. Perhaps the best way for implement it is know if is possible change a few properties of a panel for have the same behavior of a window. Many thanks for the help. -- View this message in context: http://forum.world.st/Best-way-for-change-a-window-style-tp3032341p3032341.… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] IRC meeting next Tuesday, January 4, at ...?
by Adrian Lienhard Jan. 5, 2011

Jan. 5, 2011

Hi all, During the last meeting [1] we decided to do the next one on January 4 but we didn't decide when to start. The previous meeting started at 20:00 CET/UTC/GMT+1, which may not be optimal for people in other time zones. If somebody likes to suggest another time, please let us know soon!

Re: [Pharo-project] [Pharo-users] Minimal pharo

Hi Annick. I don't know which image they told you, but if you take a PharoCore 1.1.1 from here: http://www.pharo-project.org/pharo-download/stable-core And you evaluate: ScriptLoader new cleanUpForRelease. And then save and quite, the image is 6.8 MB. Another hack I sometimes do is o put all all classes with the default category. You can still can browse and recompile the whole image. Most production enviroments don't care about categories...they make sense when developing. (not everybody agree). But anyway, if you then evaluate: Smalltalk allClassesAndTraitsDo: [:each | each zapOrganization ]. Symbol compactSymbolTable. Smalltalk garbageCollect Then the resulted image is 6.1 mb ;) If you then evaluate: "Compact all MethodDictionary instances" | oldInstances newInstances | oldInstances := MethodDictionary allInstances. newInstances := oldInstances collect: [ :md | (MethodDictionary new: md size) compactCopyFrom: md; yourself]. oldInstances elementsForwardIdentityTo: newInstances. "Different cleanUps" TextStyle allSubInstancesDo: [:ts | ts newFontArray: (ts fontArray copyFrom: 1 to: (2 min: ts fontArray size))]. "Clean all Monticello related stuff. You won't be able to browse packages for example" MCWorkingCopyBrowser allInstancesDo: [:each | each flushAllCaches ]. MCWorkingCopy allInstancesDo:[:wc| SystemChangeNotifier uniqueInstance noMoreNotificationsFor: wc. wc unregister]. SystemChangeNotifier uniqueInstance noMoreNotificationsFor: MCPackageManager. SystemChangeNotifier uniqueInstance noMoreNotificationsFor: MCWorkingCopy. "Most application don't need sound" SoundService default: nil. SoundService unregister: DummySoundSystem. SystemChangeNotifier uniqueInstance noMoreNotificationsFor: (Smalltalk at: #RecentMessageSet). TranscriptStream newTranscript: ThreadSafeTranscript new. ImageSegment classPool at: #RecentlyRenamedClasses put: Dictionary new. ExternalSettings classPool at: #RegisteredClients put: Set new. Locale classPool at: #LocaleChangeListeners put: nil. "Clean all the changes" ChangeSet resetCurrentToNewUnnamedChange Set. ChangeSet current initialize. ChangeSet classPool at: #AllChangeSets put: (OrderedCollection with: ChangeSet current). Symbol rehash. 3 timesRepeat: [ Smalltalk garbageCollect. Symbol compactSymbolTable ]. You will have a 5.9 MB image :) is that enought? If not, you can start unloading packages. Esteban did a lot of work with this of IPhone images. You can ask him. ps: I wonder if any of those scripts should be added to ScriptLoader Cheers Mariano On Tue, Jan 4, 2011 at 6:48 PM, Annick Fron <info(a)afceurope.com> wrote: > Hi all, > > I have now tried the minimal images indicated by Torsten and Stephane, on > Windows it amounts to 9.1 Mega in memory ... > Would it be smaller on Linux ? > Yet, I still need a shoe horn, having only 8 M ram from which 1.5 is > already taken by the kernel... > Any idea to downsize even more ? > Best regards > > Annick Fron >

by laurent laffont Jan. 5, 2011

Jan. 5, 2011

Hi, I've updated ConfigurationOfPharo 1.2-beta2: Added: - Mocketry - XMLSupport - Autotest - Shortcuts-Help more tests and Help. I've put methods in categories. Can someone check ? For independent Help packages, shouldn't we create a ConfigurationOfPharoHelp ? Cheers, Laurent Laffont Pharo Smalltalk Screencasts: http://www.pharocasts.com/ Blog: http://magaloma.blogspot.com/

Yes, we will look into setting up a Mac and a Windows slave soon. One idea is to use an older intel mac and install windows there as a virtual machine and use this machine for both windows and mac. Alternatively, Hudson can have Amazon E2C slaves... for windows, that would be an alternative (but an expensive one). Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe.

[Pharo-project] Hudson Win setup build
by Torsten Bergmann Jan. 5, 2011

Jan. 5, 2011

Would be nice if Hudson could also build the Pharo windows setup automatically in the future. Should be easy to setup. I know thats not the highest prio but I wanted to check if it is possible anyway (dont know what kind of machine the ci server is currently runnning on). Since I think VM's are built in the future via Hudson too there must be access to a win32 machine anyway. Thx T. -- NEU: FreePhone - kostenlos mobil telefonieren und surfen!

[Pharo-project] Generators for Pharo Xmax wish)
by Ralph Boland Jan. 5, 2011

Jan. 5, 2011

I earlier posted a Xmas wish that Pharo add generators (steal the generators code from Squeak). No one appeared to be familiar with them. The generators code was added to Squeak by Andreas Raas. The class Generator can be found in Squeak as a subclass of Stream. It's about 140 lines of code and, as I said before, is really useful and needed in order for me to port some of the packages I am developing from Squeak to Pharo. Class Generator is tested in class GeneratorTest which also serves as examples of uses of Generators. So please, someone go steal the code! And stealing is easy. For example I stole the following comment on class Generator directly from the class comment: " A Generator transforms callback interfaces into stream interfaces. When a producer algorithm provide results as callbacks (blocks) and a consumer algorithm expects streamable input, a Generator transforms one into the other, for example: | generator | generator := Generator on: [:g| Integer primesUpTo: 100 do:[:prime| g yield: prime]]. [generator atEnd] whileFalse:[Transcript show: generator next]. " Regards, Ralph Boland

> Finally I implemented the posibility of create a custom windows in > CLFramework. That really rocks! Looks cool. And I'm glad that you continue working on it since the result is really impressive. One of my goals this year is to find the time to have a look at UI framework and to start building one or the other small helper tool with it to give feedback. Is it working with 1.2 already? What is planned next! Thanks Torsten -- Neu: GMX De-Mail - Einfach wie E-Mail, sicher wie ein Brief! Jetzt De-Mail-Adresse reservieren: http://portal.gmx.net/de/go/demail
