Re: [Pharo-users] Alpha 3.0 error on starup on Mac OS X Lion

by StÃ©phane Ducasse

Thanks this is bug due to one my my recent changes. Now this bug is really interesting because it shows that we will have some work before we can use Pharo 200% from the command line in headless mode. The bug is due to the fact that we should change the world and to change the world we should kill the UIProcess, but killing the UIProcess is like shooting in your head. The changes I did are working well in interactive mode but not in headless and since the build and integration server are running headless we are in trouble. So we will take a pragmatic road and do the updates in inetractive mode and push the results on the build server (esteban the great wise proposed it and I think that we should do it that way). But we will have to think about an infrastructure where we can modify the complete system while running it. And the code evaluation is one part.

(Copy/pasting same method twice is not an answer). I am not asking for changing things. But i think that implementation would be simpler, if Trait do not have to support class/metaclass duality. -- Best regards, Igor Stasenko.

I think such a behaviour is doable in Glamour, which means there is most probably a morph behind. Maybe Doru could answer better than me :) Ben On Jul 1, 2013, at 2:36 PM, basilmir <mircea(a)unom.ro> wrote: > Does Morphic include a control similar to this?

Does Morphic include a control similar to this? (jpeg attached)

by basilmir

Does Morphic include a control similar to this? (jpeg attached) I need a two column graphics element (key, value pair). Some of these key value pairs are grouped under a category which can (optionally) collapse. Is there something similar in Morphic - Pharo, Squeak?

Yet the current trait model is based on trait and class trait, and that's consistent with the class model. If you want trait to be applied only on one side: - we have to refactor a lot of stuff, because a lot of our current code rely on this model. - you have to provide a new way for managing instance/class-side dependancies: For example, if one the class side you have: "self class blah" how can you ensure that the class side has the implementation you expect? On the other hand if you want a trait to be applied only on the instance side: provide only instance-side methods. And if you want a trait to be applied only on the class-side: provides only class-side methods. So everything's fine with this regard IMO.

Re: [Pharo-users] how to draw this Shape??

by ClÃ©ment Bera

I don't know how to do it with Polymorph. You can do it with Athens (by polishing this code) : surf := AthensCairoSurface extent: 100@100. surf drawDuring: [:can | surf clear. can setPaint: Color red. can drawShape: ( can createPath: [:path | path absolute; moveTo: 0@25; curveVia: 25@0 to: 50@ 25; curveVia: 75@0 to: 100@ 25; lineTo: 50@75; lineTo: 0@25 ]) ]. Display getCanvas drawImage: surf asForm at: 25@25 Athens is by default in Pharo 3. If you are on Pharo 2, there is a configuration to load it somewhere : Gofer new smalltalkhubUser: 'Pharo' project: 'Athens'; configuration; load. ConfigurationOfAthens loadStable. But I don't know if you have to specify a version for Pharo 2.0 or something like that. 2013/7/1 irfankhan1 <irfankhan(a)hotmail.ca> > Hello I am trying to draw a Valentine heart shape as shown below, Border > of > this shape should be dashed bordered. > <http://forum.world.st/file/n4696507/Lavender-sachet-heart-shape.jpg> .

Hello I am trying to draw a Valentine heart shape as shown below, Border of this shape should be dashed bordered. <http://forum.world.st/file/n4696507/Lavender-sachet-heart-shape.jpg> .
