Usually (and if possible) morph should try and detect what parts of his drawing needs to be updated and update only minimum part covered by clipping region. But that implies some internal knowledge about morph's geometry etc.. and that's why a default implementation simply (re)draws everything. > Thanks :) > > I will ask today if I can make a video of my work because is very > impressive of what we can do on Pharo with the framework! > Please do. > And if the reDraw is functional we certainly have the same performance > with Pharo! > Come to see me and we will look how we can optimize it :) > So good news :) > > Tristan > -- Best regards, Igor Stasenko.

[Pharo-project] How to redraw only a part of a morph

by Tristan Bourgois

Hi! I try to optimize the graphic framework I'm porting. I have good performance but I have some problem to reDraw the morph of my view. When I reDraw my morph I use 'invalidRect:' with the bound of the part I want to reDraw but every step my morph is entirely reDraw. Does I have to use another method? Or someone can explain me how pharo manage the repaint of morph? Thanks :) I will ask today if I can make a video of my work because is very impressive of what we can do on Pharo with the framework! And if the reDraw is functional we certainly have the same performance with Pharo! So good news :) Tristan

Re: [Pharo-project] Multiselect in method pane

Two compiled methods with same byte code, even with different selectors are equals (and people laughed at me when I found that disturbing) Ben On Mar 28, 2013, at 11:51 AM, stephane ducasse <stephane.ducasse(a)free.fr> wrote: > > On Mar 28, 2013, at 11:21 AM, Norbert Hartl <norbert(a)hartl.name> wrote: > >> What is the rationale for having the method pane as multi-select list?

Re: [Pharo-project] about a new pharo site

by Camillo Bruni

I like this http://vagrantup.com and I think you have to immediately address the users by letting them chose I am new => show how to download details and everything I am pro => directly show raw links / discussions ... I am a company? :D of course one should not exclude the other, but we should optimize for the targeted audience On 2013-03-28, at 11:49, Esteban Lorenzano <estebanlm(a)gmail.com> wrote: > Hi, > > I would like to discuss something about a complete redesign of the site because right now, while it was good some years ago, now is old and confusing... > I would like something clean and easy, more or less like the ruby on rails site: http://rubyonrails.org > > ideas? > > Esteban > > ps: this is a brainstorm for a change that will take time, do not expect too much too soon :)

[Pharo-project] about a new pharo site

by Esteban Lorenzano

Hi, I would like to discuss something about a complete redesign of the site because right now, while it was good some years ago, now is old and confusing... I would like something clean and easy, more or less like the ruby on rails site: http://rubyonrails.org ideas? Esteban ps: this is a brainstorm for a change that will take time, do not expect too much too soon :)
