Re: [Pharo-project] Toward MVP
by Schwab,Wilhelm K June 14, 2011

Attached is code to produce something I need. It shows a list of items; click one and the text goes into the box below the list. The user can also type into that box; there is no sense of responsibility about saving the user's work. The mind set is that the list provides most things of interest, and it should be possible to "say anything" just in case. Click the button, and the text in the bottom field goes into a log file, complete with time stamp. It's not big deal, but neither should be creating it. Start with a model: EventLogger>>initialize super initialize. quickList := ListModel new list:#( 'Start' 'BP down' 'BP up' 'End' '***SNAFU***' ); yourself. fileSequence := ... "the log" Add the attached code. Among the important features are transparent handling of the selection index for the list and having something (following Dolphin, call them presenters) between the model and views (morphs). Models should not know or care about their selection index; the morph/view should do that (in Pharo, the ListPresenter is the natural home for it), and can do so in a way that "just works" for most purposes. The text presenters have been more trouble than I expected, but they bring with them some very important concepts. Dolphin's ViewResource is looking for a home (whether it will find one is open for bets), and the volley of events between model, view and presenter is starting to appear. Among the important tests (not yet realized as unit tests - sorry) is one model with multiple views; change the model and the views update. Dolphin's layout managers are very powerful, and while the pieces to make them exist in Pharo, I have yet to master their use. A common trap is to use top-level views when something composable is possible and desirable. I am not yet sure what to do about that.

It looks like you are "thinking big," which is great. I am not a big believer that native widgets equate to speed, but, there are times when some native code goes a LONG way in that direction.

[Pharo-project] Polymorph: PluggableMultiColumnListMorph vs. PluggableListMorph
by Schwab,Wilhelm K June 13, 2011

June 13, 2011

Gary, all, I just ran into a question: among all of the #newList* methods, is there a good way to refer to a particular subclass? Since these methods ultimately just create a morph, I am doing that with a little hard coding of some options. Is there a better way? Bill

[Pharo-project] Tiling Window Manager - status update
by laurent laffont June 13, 2011

June 13, 2011

First thanks to all people that send patches (and tests !!). Still not haven't merged all of them - don't hesitate to post in repository so code is not lost. Yes I will merge layout policies. Gofer it squeaksource: 'TilingWindowManager'; package: 'TWM'; load. (Smalltalk at: #StandardUITheme) beCurrent. (Smalltalk at: #TWMBar) showTWMBar:true. Tested on PharoCore 1.2 and Pharo 1.3. Now this has support for world snapshot, that means you can arrange the windows and take a snapshot of the layout. Then you can restore these layouts later. (icons camera, <, > and trash). I'm not entirely satisfied with this, thanks for feedback. In Pharo 1.3 there's initial integration with KeyMapping. To load: Gofer it squeaksource: 'ShortWays'; package: 'ConfigurationOfKeymapping'; load. (Smalltalk at: #ConfigurationOfKeymapping project version: #bleedingEdge) load. Then in settings browser > Keymappings > Tiling Window Managers you have all actions of the dock mapped. Not all shortcuts are working, don't know why, if people can test and find good shortcuts thank you. Creating a nice Metacello Configuration for TWM will be appreciated :) Cheers, Laurent Laffont - @lolgzs <http://twitter.com/#!/lolgzs> Pharo Smalltalk Screencasts: http://www.pharocasts.com/ Blog: http://magaloma.blogspot.com/ Developer group: http://cara74.seasidehosting.st

[Pharo-project] FFI on Mac OSX
by Jan van de Sandt June 12, 2011

June 12, 2011

Hello, I'm trying to use an external library through FFI. On the Mac (Snow Leopard) I get the following error on the console: tryLoading /Applications/Smalltalk/Cog.app/Contents/Resources/libicui18n.dylib ioLoadModule(/Applications/Smalltalk/Cog.app/Contents/Resources/libicui18n.dylib): dlopen(/Applications/Smalltalk/Cog.app/Contents/Resources/libicui18n.dylib, 10): no suitable image found. Did find: /Applications/Smalltalk/Cog.app/Contents/Resources/libicui18n.dylib: mach-o, but wrong architecture What does "mach-o, but wrong architecture" mean? 64bits instead of 32 or something else?

[Pharo-project] merging images?
by Esteban Lorenzano June 12, 2011

June 12, 2011

Hi, I wonder if there is a way to merge two Form objects into a new one? I'm trying to add "status" to some icons, something like "filter active" an icon with a mark, "filter inactive", another mark. Of course, I can create two different icons, but I thought "it would be nice to have this as a general functionality" :) Cheers, Esteban

We should really try to do that with 1.4, it will make everything simpler and easier to manage. Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.
