Wow, I have to say that this is a suprisingly unfriendly respnonse. You asked me if we were using release or renderer, and this was my answer. I say suprisingly unfriendly because I have been following this list for quite some time and have not seen such a response before.
This was not meant to be unfriendly. Sorry for this. It seems to me that you are await that qooxdoo is already feature-complete. I just want to put it in perspective. We are working hard to bring it step by step to be more usable for the masses. We are really interested in feedback and contribution. But some people don't seem to understand that this costs some time to get done.
The only thing I actually want to say is that it is probably not realistic if you want to use qooxdoo without some time investment to get it working for your needs. We have not just reached the level to allow plug-and-play. I hope you can accept my excuse. What you understand was not really my intention.
Sorry again. Sebastian
I fully understand it is "not your problem" - that is one of the tradeoffs with using Open Source, my problem is NEVER your problem.. sometimes our needs will overlap, sometimes you may have a solution for my problem readily available, but my problems will never be "your problem". However, in a project that is expecting to benifit from input and possibly code from its users, (which you would from my co - anywhere from 2-5 major products would use it, somewhere between 2k and 7k users on those apps, and 1-5 developers adding too and reviwing Qx code - depending on how usefull the toolkit proved to be) it is not usually a good idea to respond with "this is not our problem" or "we are at version .14, dont expect us to [work]" For a project like this to be successfull, it must be adopted by users, and I can guarantee that managers seeing a response like this from the lead dev for a project will quickly veto the use of the project. It has happened to me before - unable to use a good tool because the lead devs made responses like this in publicly visible forums. On 1/6/06, Sebastian Werner <[EMAIL PROTECTED]> wrote:J. Russell Smyth schrieb:Renderer. this would have to be our target if we were to use Qooxdoo, for performance and advanced features, and we do not have the opportunity to do a major rewrite just after adopting a new tool.I am sorry. But this is not our problem. qooxdoo is currently at version 0.1.4. Don't expect that it is as stable and feature complete as other native toolkits in versions beyond five and many years of development.

Russell Smyth schrieb:I am curious about some "construction" decisions. Is there reasoning behind making QxListView from "div" components rather than "table"? My main curiosity is we are evaluating QooxDoo for some major internal applications, and want to make sure we understand as much as possible before making a decision.The old qooxdoo use sub-node-structures many times. This is true for tables, where you need to move the children to the desired target node, which is not the real node of the parent itself.I am not able to understand what you are saying here, other than old qooxdoo used tables?The new ones layout decisions use divs all over and try to create as less as DOM nodes as necessary (as they are performance critical).Yes, I understand that creating fewer dom nodes if possible is an advantage, but do you not also discard all of the formatting capaiblities built natively into table structure? Dont get me wrong, in part I see the elegance of using div's and your own layout mechanism where possible, but question the value in tabular data?One reason I ask this is we have had to deal with large tables and sorting here, and have had to do some interesting stuff to make them fast - we have at least one app with a requirement for tables containing 5000 rows with sorting capability - with IE support a must. For QooxDoo, if you load QxListView with 5k rows in the demo, it dies.. it has actually crashed my IE, and when it dosnt, it just falls asleep.. even with only a few k rows, sorting is unacceptably slow...It really dies? What means "dies" for you?Well, as I stated, it somtimes crashes IE. Other times it will just spin CPU cycles at about 99% for very long periods of time (10-20 seconds for 5k rows)Is the loading the problem or the sorting of the data.each additional 1k items takes progressively longer, so loading is also a problem - somewhere around 15 seconds to load But the real problem is sorting. And yes, it is MUCH worse in IE.To handle sorts of large arrays at client is a problem because the Internet Explorer has some huge performance impacts there (much bigger than Firefox). If you have many items in your list it is probably the best to do the real sorting at the server and just send the new data via AJAX to the client.doing this server side is not an option for at least one of the applications. I myself dont belive that 5k rows of data is human consumable, and displaying data in this format to me is incorrect, but that is the requirement. Unfortunately, there is an existing in-house custom table component that is able to sort 5k rows in IE on a moderatly powered pc (sub what my test machine is) in sub second time, so I wont be able to sell that it is too slow because of ie :) If I can find ways to improve this, based on our in house solution, I will gladly submit a patch.
