Re: [Pharo-users] [COTDC] 77 - LazyMorphTreeMorph

by Tudor Girba

I am a MorphTreeMorph, but I only render the rows lazily as they appear on screen. Caveat: There is no rendering in the background. This means that if a row takes too long to render, you can experience a shorter or longer freeze when scrolling.

First, let me say that we really appreciate your project and we are happy with it :) Now, to avoid reinventing the wheel, I want to point you some stuff. 1) There is a GlorpDBX connection pool available. This is the package GlorpDBX-ConnectionPool. Documentation: http://www.squeakdbx.org/documentation/SqueakDBX%20connection%20pool%20for%… 2) There is a general purpose pool (for any kind of object) that also work in Glorp or DBXTalk. http://www.squeaksource.com/ObjectPool There is a package ObjectPool-GlorpDBX :) I cc'ed Panu, the developer.

Re: [Pharo-users] Parsing XML into sorted elements

Anyone have anything better? > Why do need to sort while the parser is parsing? Can't you sort just afterwards? I think this is the cleanest approach. If you want to sort the elements immediately than you need custom classes like you wrote. Did you have a look at XMLPluggableElementFactory ? You can set a nodeFactory in the XMLDOMParser that should emit your classes while parsing. In your custom class there should be a possibility to override nodesClass in a clean way to get the list changes done. If not that would be a needed enhanced to the parser. Norbert
