by Alain Plantec

Hi Sean, No, Iâve not studied Self Morphic but I hope that I understand well the idea and a part of its design. I think it is still the idea of Morphic even in Pharo but as you say, pollute with special cases. The Bloc core is a reimplementation of this Morphic idea. I hope you will appreciate its uniformity. (yes, you can open a World in a World :) ) Cheers Alain > Le 25 fÃ©vr. 2015 Ã 23:03, Sean P.

Re: [Pharo-users] BaselineOf vs ConfigurationOf

by Peter UhnÃ¡k

Thank you! If the BaselineOf is independent maybe we could repurpose Versioner - because even if tags and branches are handled by git, the load order and dependencies are still required and doing that by hand is too much work. :) Also maybe the docs (which I found just nowâ¦ so shame on me for not looking harder) should be updated to recommend people to use BaselineOf always https://github.com/dalehenrich/metacello-work/tree/master/docs Peter On Thu, Feb 26, 2015 at 8:23 PM, Dale Henrichs < dale.henrichs(a)gemtalksystems.com> wrote: > > On 2/26/15 4:41 AM, Ben Coman wrote: > >> Just a random query (especially since I haven't played with BaselineOf >> and I might misunderstand something)... >> should #baseline: be moved out of the ConfigurationOf class so that we >> consistently have a BaselineOf class in both cases: git & monticello. >> > Haha, you are misunderstanding ... the two classes are separate because > they are independent classes.

Re: [Pharo-users] What UI direction now (or in the near future)?

by Alexandre Bergel

> Will be internal drawing methods in Morph switched to Athens drawing by default in future? You can do the drawing in Athens. It is up to you. Using Athens will make your rendering faster and nicer (if you use the Cairo binding, which is the default binding). If I would be a beginner who want to understand what there is, I would simply give a try to Spec, bloc, and plain Morphic. In any case, your application logic should be independent from the UI. Because UI is frequently changing (have you though about exposing your UI on the web?)

Thanks (to all). So, the best way (for now) is the old friend Morphic.

What about future, bloc is about future. Now doing it would be silly but there is a risk. So do we die because we do not move and continue to have a huge system that nobody really understand well or do we try to improve with the risk of failiure. Now alain is one Morphic expert, he wrote miro and miro2 with the ancestor of Athens (Rome). > support, long-term issues? We are working on documentation. You can for example, open Bloc and execute the examples. You can try to turn some of them into examples. This is what I did and it helps alain. > Look at Marina CMS framework, even used for Pharo website, but not maintained now... Can I ask yourself a question? What do you do that is simple that could help us to avoid to focus on simple things and concentrate on the difficult ones. You see this is not a huge challenge. But you should ask yourself the question. I'm sad about Marina but we could not guess that nicolas would leave Smalltalk like that. About Bloc I think that the design stabilized and now it is ready for other people to have a look and play with it. Before it was not constructive. We got several iterations (I did not do much, just read the code and ask stupid questions). But I see that it is getting there. Now Bloc-Core is not about widget it is about events, drawing, listeners, space. Then we started to see that we can use Spec on top of Bloc. So this is why I'm starting to clean Spec. But commenting pragmas is a task that anybody could do but apparently I'm the only that is doing. The next steps are: - expose valueHolder via getter (named xxxHolder for consistency) - remove all the whenChanged.... that are pure delegation - verify if the adapter can be just use during widget creation to bind the widget to the model (and not as a middle like now) - cleaning more. Now if somebody wants to step in I can reviews changes. > > B) Is Bloc prepared with Retina displays in mind (perfect smooth fonts and graphics, scaling, more detailed images for retina etc.)? As much as Athens with a cairo back end is. Bloc is 100% based on Athens. Athens is a vectorial canvas API > > C) Is current keyboard + UI component focus support perfect or pain in... Nothing is perfect. My mac crashes. I cannot open my old keynote presentations because keynote 09 crashes. You see the world is complex. Now when keynote crashes I cannot do much.
