Re: [Pharo-project] A lil simplification of MorphTreeNodeMorph

by Tudor Girba

This is great! I tested it on Glamour and it looks pretty cool. And, it is definitely snappier. I tested LazyMorphTreeMorph it on a list with 1 million items in the context of Glamour with a pagination of 50 items I got: - before: 6414 ms - after: 3526 ms The code I used is (works in a Moose image, or after you load Glamour): Time millisecondsToRun: [ | browser | browser := GLMTabulator new. browser column: #one. browser transmit to: #one; andShow: [ :a | a tree tags: [ :each | {each even printString} ]; showOnly: 50 ]. browser openOn: (1 to: 1000000) ] Cheers, Doru On 6 Apr 2011, at 18:01, Igor Stasenko wrote: > okay.. i found one bug > > forgot to add cellPositioning: #leftCenter; for colum wrapper morph > > > -- > Best regards, > Igor Stasenko AKA sig. > <Tree2.3.cs> -- www.tudorgirba.com "What we can governs what we wish."

Re: [Pharo-project] Pharo 1.2.1 Problems with OpenGL

When I tried to build a configuration roadmap that can be reproduced by students I failed to remember that it's not possible to use the Monticello version of OpenGL anymore. It's necessary to use a debugged version provided by Javier Pimas (which I include here as an annex). Anyways I suggest that either Javier version is uploaded into Metacello repository or a pointer to the file is provided & the Collaborative Book is corrected in this respect.

Why not? RBClass, RBMetaclass and RBMethod are central parts of the model.

It's an opportunity to get rid of a lot of cruft that has accumulated on SqueakSource during the last years... But still there can be something good and valuable. I'd migrate that with some #archive tag or something. The same goes with code from other Smalltalks. Like Smalltalk Goodies archive back from 90's, there are quite some interesting code, which I'm still using.

Re: [Pharo-project] Delay bug

We managed to resolve our initial problem with the process scheduling [1]. All Cmsbox customers have been migrated to Pharo and it works very reliably now. Gary, maybe you could open a ticket already now and post what you know at this time to get early feedback.

Wow, looks great! I think it's a good idea to *not* automatically migrate projects from SqueakSource ;).
