[Pharo-project] tabs with close button
by Tudor Girba Jan. 14, 2010

Jan. 14, 2010

Hi, Is there a Tab widget that offers the possibility of closing a tab (maybe with a small x button near each tab)? Cheers, Doru -- www.tudorgirba.com "There are no old things, there are only old ways of looking at them."

Hi all! I presume this bug is also in Pharo so I CCed.

Yup, just fix it! :) Sorry for the bug guys. regards, GÃ¶ran

[Pharo-project] ConfigurationOfAlien
by Fernando olivero Jan. 14, 2010

Jan. 14, 2010

Hi, just added ConfigurationOfAlien to the MetacelloRepository. To load Alien using Metacello configurations evaluate Gofer new url: 'http://www.squeaksource.com/MetacelloRepository' ; package: 'ConfigurationOfAlien'; load. (ConfigurationOfAlien project version:'1.0') load. ( John please update the ALIEN squeaksource page with the previous text ) Note: Using the available MAC VM i the pharo page, you should be able to run the test correctly. ( the alien plugin 'IA32ABI 7 May 2009 (e)', is compiled inside that vm, there's no need for the external one) Metacello question: If i want load Alien Examples, the package Alien-MacOSExamples, but don't want to add them to the above configuration , should i create a new #versionXXX method ? Or provide a class side method like for example ConfigurationOfAlien>>loadWithMaxOsExamples (ConfigurationOfAlien project version:'1.0') load:#('Alien-MacOsExamples') Saludos, Fernando

Hi David, I cannot write my changes. So you can have them in attachment. In these .cs, there is a merge with your version .15. And it works with Pharo.

[Pharo-project] Metacello configuration of Magma
by Miguel Enrique CobÃ¡ Martinez Jan. 14, 2010

Jan. 14, 2010

I have published the Metacello configuration of Magma in the MetacelloRepository of squeaksource.com. Take a PharoCore 10506 and evaluate in a workspace: Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfMagma'; load. Then load the default group that loads the Magma Client: ((Smalltalk at: #ConfigurationOfMagma) project version: '1.0r43') load this is equivalent to: ((Smalltalk at: #ConfigurationOfMagma) project version: '1.0r43') load: 'Client'. To load the Magma Server evaluate: ((Smalltalk at: #ConfigurationOfMagma) project version: '1.0r43') load: 'Server'. And to load the Magma Tester evaluate: ((Smalltalk at: #ConfigurationOfMagma) project version: '1.0r43') load: 'Tester'. This last one will load also OSProcess that is used by the Magma Tester to do the stress testing of Magma. Notes: - WriteBarrier is a package loaded by Magma. This requires NewCompiler as dependency but as NewCompiler is being rewritten currently, isn't loaded as a dependency. - Magma makes use of ProjectHistory that doesn't exist anymore in Pharo. Magma will fix this by conditionally testing for ProjectHistory by means of Smalltalk at: #ProjectHistory. - This is the first configuration for Magma and will be modified in response to the feedback you give me. - Currently the blessing is #development. Maybe this should be marked as #stable in order to load with: ((Smalltalk at: #ConfigurationOfMagma) project latestVersion) load. This way it will install the latest non-development version available in MetacelloRepository without having to specify a version number. - This configuration executes a preLoadDoIt with the following code: Smalltalk at: #EventSensor put: InputEventSensor because EventSensor was removed from Pharo, but Magma add some methods to EventSensor class. I *really* need feedback about the risks of doing this. Any feedback is welcome. Enjoy! -- Miguel CobÃ¡ http://miguel.leugim.com.mx

[Pharo-project] regex gurus anyone? Method category refactoring?
by Stan Shepherd Jan. 14, 2010

Jan. 14, 2010

Hi, I'm looking at getting the window building tools to provide some information to a theme, so it can provide meaningful themeing (in the first instance window color) . So I have a list of the senders of #labelled:, that currently are sending virginal SystemWindows with no models. I'd like to do a regex on the scoped list, of the form (SystemWindow labelled: 'later') model: self. becomes (SystemWindow labelled: 'later' justSetModel: self) model: self. So the theme can see the model at the time it's asked to provide the color. ie (SystemWindow labelled: foo ) model: bar. becomes (SystemWindow labelled: foo justSetModel: bar) model: bar. Any takers on a regex for that? Also, how do you add all the methods changed to category *MyWindow-Changes in one go? Bear in mind no package browser in the dev or one click images. Thanks, ...Stan -- View this message in context: http://n2.nabble.com/regex-gurus-anyone-Method-category-refactoring-tp43901… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] EventSensor vs EventInputSensor
by Miguel Enrique CobÃ¡ Martinez Jan. 13, 2010

Jan. 13, 2010

I have a question about EventSensor. In Pharo doesn't exists anymore, it was replaced by InputEventSensor that has this class comment: An InputEventSensor is a replacement for the old Morphic EventSensor framework. It updates its state when events are received so that all state based users of Sensor (e.g., Sensor keyboard, Sensor leftShiftDown, Sensor mouseButtons) will work exactly as before. The usage of these funtions is discouraged. I am installing Magma on a Pharo core image and Magma uses EventSensor, by adding some methods to this class. As the class doesn't exist it shows the following message: This package depends on the following classes: EventSensor You must resolve these dependencies before you will be able to load these definitions: EventSensor classSide>>maMaterializeFromGraph:using: EventSensor>>maAsStorageObject EventSensor>>maUsesStandardStorage Select Proceed to continue, or close this window to cancel the operation. If before loading Magma I do Smalltalk at: #EventSensor put: InputEventSensor. Then everything works without warnings. Also the InputEventSensor receives the methods added by Magma. My questions are: Is this valid? Must this (the InputEventSensor in the slot of EventSensor in Smalltalk) be part of the image or will be a regresion to the situation before the deletion of EventSensor? What will be the correct way to handle this, change the Pharo/PharoCore with my hack or to ask Chris Muller, the maintainer of Magma to not use EventSensor but InputEvenSensor in the case of Pharo/PharoCore? Can I be reminded of the reasons to drop EventSensor in favor of InputEvenSensor? Thanks for the answers -- Miguel CobÃ¡ http://miguel.leugim.com.mx

[Pharo-project] How can I remove a picture from background ?

Hi: I do something like this: Form setBackgroundFromImageFileNamed: '/Users/mariano/Pharo/body.png' And the picture is set as background, but then I don't know how to remove it. I look for a while but I didn't find anything. Thanks for the help, Mariano

[Pharo-project] [ANN] Icons for Mac users
by Torsten Bergmann Jan. 13, 2010

Jan. 13, 2010

>I don't know who did the icons. That was me - I used Samuel's logos as a base. I once created them for page 15 (figure 1.1.) of the pharo-by-example book where image, source, etc. files are introduced and made them available via gforge to Oscar Nierstrasz for inclusion in the book. Unfortunately he decided he wanted to have the windows icons, so I made a screenshot of the (IMHO more ugly) win icons which are now included as figure 1.1 in the book. Thanks for the conversion, at least they are used now. Bye T. -- GRATIS fÃ¼r alle GMX-Mitglieder: Die maxdome Movie-FLAT! Jetzt freischalten unter http://portal.gmx.net/de/go/maxdome01

[Pharo-project] clone vs shallowCopy
by Bouraqadi Noury Jan. 13, 2010

Jan. 13, 2010

Hi, I found the clone primitive method in the Object class. Its behavior looks the same as shallowCopy. Actually, shallowCopy just sends basicShallowCopy wich calls the same primitive as clone (primitive 148). a1 := Array with: Object new. a2 := a1 clone. a1 == a2. "--->false" a1 first == a2 first. "--->true" When I look to senders (in a pharo-dev 12.2) I find the following: -62 senders of clone. -2 senders of basicShallowCopy -66 senders of shallowCopy Looking to implementors I found: -9 implementors of shallowCopy (all are kernel classes) -1 implementor of basicShallowCopy (not surprizing) -6 implementors of clone (all are kernel classes) Most implementors of clone and shallowCopy are different. Yet, implementations done by same classes are the same behavior. Other implementations of clone answer self, because there are for objects that should/can't be copied (e.g. SmallInteger, Character). So, I suggest to remove clone and use shallowCopy instead (better/more precise name). Anybody has any reeason against? Otherwise, I'll do it. Noury
