I plan to inject the new methods into a Morph Morph>>fullDrawOnRomeCanvas: aCanvas Morph>>drawOnRomeCanvas: aCanvas which should tell the morph to use a different instructions/commands to perform drawing, to conform with RomeReferenceCanvas protocol. I don't want to repeat a balloon canvas protocol. Then, eventually, when we will have everything ready, we will be free to use different rendering backend than Balloon canvas. And its important to make it a non-intrusive. So, the plan is: - create a separate package, which will contain extension methods to Morph and its various subclasses. And maybe some little classes. - this package !!_should not_!! have any dependencies on Rome , and should be loaded cleanly, even if you don't have Rome installed. It only should conform with Rome canvas protocol for implementing rendering. This will ensure a backend agnostic nature of new morphic rendering code. If you think this plan is cool, then lets pick a package name and repository, and i will start happy coding :) >> >>> Regards, >>> Â Â Â Â Â Â Javier. >>> >>> 2010/5/23 Igor Stasenko <siguctua(a)gmail.com> >> >> >> -- >> Best regards, >> Igor Stasenko AKA sig. >> >> _______________________________________________ >> Pharo-project mailing list >> Pharo-project(a)lists.gforge.inria.fr >> http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] MetacelloCreateConfigurationTutorial + ProfStefBrowser really cool
by laurent laffont June 3, 2010

June 3, 2010

Hi, I've just created a ConfigurationOfScamper using MetacelloCreateConfigurationTutorial (see http://code.google.com/p/metacello/) in ProfStefBrowser, it's really funny. Can MetacelloCreateConfigurationTutorial be included in Pharo (Dev) 1.1 ? Cheers, Laurent Laffont http://pharocasts.blogspot.com/ http://magaloma.blogspot.com/

[Pharo-project] about a digest for the mailing-list
by StÃ©phane Ducasse June 2, 2010

June 2, 2010

Hi I think that lot of people are overwhelmed by the flux of mails. I would like get us doing the following: - have an announce mailing-list with a low traffic and important announces - having a monthly report of items. For the second point we could have a group of people picking info in the list and creating a wiki page and at the end of the month sending it in the announce list. What do you think? Who could help? Stef

Re: [Pharo-project] [squeak-dev] Update on Morphic 3
by Fernando olivero June 2, 2010

June 2, 2010

GREAT WORK JUAN! the quality is superb! it's amazing to see Morphic3 in action! When can we get our hands on it? If you need any help/tester for the project i'm up to it! Fernando pd: just a minor remark on the web page: i think the pictures to the right and left should have a distinct label, explicitly distinguishing Morphic3 and the other rendering engine used.
