Re: [Pharo-dev] Roassal vs Roassal 2

wow 500.000 is a huge number for my needs. How about animation ? I assume its similar situation there too. Well then I have little reason not to use it. Hopefully I will make a few contributions too :) When I first used Roassal I was sceptical on its design , but now that I see more and more people using it and more documentation about it I see its going to a direction I wanted to go. I also see that Roassal works well with Morphic and Spec which is very good too for my needs. Great job ! Should ask questions here or in stackoverflow ?

Hi! Currently Roassal2 _does not have any optimization_, which does not imply Roassal2 is slow. You can easily have 500 000 elements on screen without having much lag. In the future, we should be able to plug QuadTree in Roassal2. But currently, nothing has been done in that respect (except keeping the core of Roassal clean and lean :-).

yes I am using Roassal 2 now , I also care a lot about the performance cause of my project Hyperion which is and going to be a GUI builder and vector editor , I want to make GUIs with Roassal so performance is an issue.

GToolkit

by phil＠highoctane.be

I've been working in a data acquisition scenario today and GToolkit proved to be of immense help. Working in the live application, looking around for data (including file contents), and inspecting it all + live debugging is really a sweet experience. With CommandShell I may not have to leave the environment... Phil

Re: [Pharo-dev] Which Character Encodings do you want/need in Pharo ?

by kilon alios

Ok this is strange the ISO 8857-7 is available with Chrome as an encoding , I tried it and it turns Greek to weird signs. Actually I tried also several others available for Greek by Chrome and none works apart from the default which is UTF-8 .... Also you can ignore my request as I tried Pharo with True Type fonts with Arial and it can display Greeks just fine.

I think this something that (native) speakers should help with ;-) Remember we have full Unicode Character/String capable classes, as well as good UTF-8. Those cover all languages, in theory.

I am not in any urgent need as I rarely use (like almost never) my native language in reading or writing when it comes to anything related to computers, apart from facebook friends. But I would like to see it added to pharo , its ÎÎ»Î»Î·Î½Î¹ÎºÎ¬ or as you know it "Greek". I assume the most popular encondings to have would be Chinese and Hindu ?
