tobias if you want to think that I'm an asshole and I do not want to have a better UI, you are free to think that. Now this is not the case.

Now the question is do we want that in addition to - event, - announcement - changed We are working ***HARD*** to remove event and system changenotifier. Design is not layering, it is about bringing the right infrastructure in place. So if signals are important/good then they should be not in competition to other but either integrated into or we should migrate the code to the other abstractions. >> In the case of the UIBuilder of void, > > Void?

Yes and this is why we do not want that.

As I said, we do not want to have four ways to emit announcements, we need one cool widgets set (merging the best of what exist), in the past we had 4 different ButtonMorph. I want one excellent one. So to get there it will take engineering time. Just to evaluate solution. Stef

Nothing and this is the point in the case of I would prefer to have totally new widgets instead of long list of hiearchy like PluggableButtonMorphPlus. So I did not check the code of Builder so may be you do not do that and this is good. But it requires TIME to have a real look: not just load and say this is loading. > It's just a default set.

Re: [Pharo-project] List weekly digest

by laurent laffont

This is cool. Thank you ! Could you put it directly on pharo-project.org website ? Or may be there is a way to use RSS in pharo-project.org to display the weekly news ?

Re: [Pharo-project] about FS: a roadmap

by StÃ©phane Ducasse

- first cut at rename support - for FSReference and FSFileSystem (only FSDiscFilesystem). - added fullName to FSPath, FSReference, FSLocator - more comments - should do MemoryFS rename: - deprecate childDirectories and childFiles to use directories and files instead. Stef

Re: [Pharo-project] A new GUI visual designer

by Marcel Taeumel

Hi. I wrote these Widgets and the Morphic Designer mostly from scratch. There is almost no stacking of libraries. ;) Widgets need Signals and Animations which I also wrote from scratch and which do not have any dependencies other than Squeak 4.1 and later. For now, I reused: - PluggableTextMorph - TextMorphForEditView - ScrollBar - ScrollPane These I plan to replace them with new ones as well. The code itself is http://www.opensource.org/licenses/mit-license.php MIT licensed as stated https://www.hpi.uni-potsdam.de/hirschfeld/trac/SqueakCommunityProjects/wiki here . I did the whole thing, because I did not like, how the classic tool builder works or how pluggable morphs are meant to be used. Signals could definitely be integrated into Squeak (trunk) because I fixed the last serious bugs back in the last months as I worked with signals in several projects in a productive way. Obviously, I adapted the API and some great ideas of the http://qt.nokia.com/ Nokia/Qt Framework . So you could say that some widgets or the signals are just a port from C++ to Squeak. There shouldn't be any licensing issues. All widgets use several icon packages that are also meant to be used for community purposes and reflect the correct license at source code level just now: applicationCascadeIcon > "Auto-generated. > > Silk Icons > Â© 2005-2006 Mark James > Website: http://www.famfamfam.com > License: http://creativecommons.org/licenses/by/2.5" > > ^ Icons > at: #silkApplicationCascade > ifAbsentPut:[ Form fromBinaryStream: (Base64MimeConverter > mimeDecodeToBytes: self applicationCascadeIconContents readStream) ]. -- View this message in context: http://forum.world.st/A-new-GUI-visual-designer-tp3067111p3302461.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Re: [Pharo-project] [COTDC] 8 - WikiStyleHelpBuilder

by laurent laffont

I'm an HelpSystem builder which create an HelpSystem book from a wiki-like formatted string. ! Usage - Create a class-side method on the class you want to put documentation. - Add the pragma <wikiStyleHelp:> with the title of the book as parameter - The method should answer the documentation as a String (using Pier syntax. See http://www.piercms.com/doc/syntax ). ! Example MyClass class>>aMethod <wikiStyleHelp: #'The name of the book I want to write'> ^ ' ! Section 1 Some text for this section !! Subsection 1.1 !!! Subsection 1.1.1 !! Subsection 1.2 ! Section 2' And add WikiStyleHelpBuilder class>>help <wikiStyleHelp: #'Write documentation with wiki like syntax'> ^ self comment Laurent On Fri, Feb 11, 2011 at 6:29 PM, laurent laffont <laurent.laffont(a)gmail.com>wrote: > Today: WikiStyleHelpBuilder > > > Comment Of The Day Contest - One Day One Comment > Rules: > #1: Each day a not commented class is elected.

Re: [Pharo-project] [COTDC] 7 - CodeAnnotationMorph

by Alain Plantec

-------------------------------- I display code annotations that can be embedded in a browser (basic core image browser) to show useful informations about the current method or class. In order to show me in your browser, the "show annotation pane" setting must be set to true (search for 'annotation' in the setting browser). This setting is set to false by default. The informations to show are given by CodeHolder>>annotation. A methods annotation is built according to a list of requests which consists in a list of symbols. These symbols are interpreted by CodeHolder>>#annotationForSelector: ofClass:. See CodeHolder class >>#annotationRequests for more details about this list of requests. By default, the author, the time stamp, the message category, the senders and implementors count and the list of change sets in which the method is referenced are shown. Because the building of an annotation can be very time consuming (especially the implementors count),an annotation is built in background. So, I am also a good example of how a process can be used in order to build some data in background. Instance Variables codeHolder: <CodeHolder> process: <Process> codeHolder - The CodeHolder (a Browser, a MessageList ..) in which I'm embedded process - The process which is building the annotation in background -------------------------------- Cheers Alain Le 11/02/2011 18:18, Laurent Laffont a Ã©crit : > I cannot find in which case/tool it is used .... > > CodeAnnotationMorph allInstances is always empty and following senders > don't help me much. > > > Laurent > > > Le 10 fÃ©vr. 2011 Ã 21:07, Noury Bouraqadi a Ã©crit : > >> Ok, let's join the party ;-) >> >> I am a "lightweight" Morph.
