Hi,

being an avid = KDE user and working in a very Windows-centric organization, I'm very interested = by the potential of KDE (and Qt) tools running under Windows. One of the = projects I'm most actively involved in (mainly as a tester and bug reporter, though I = occasionally contributed some code as well) is kst, a great (though not so well = known) professional plotting tool.

I've just = subscribed to this list to be able to follow progress on the KDE Windows front, and = also to be able to get some advice on kst under Windows, as version 2.0.0 (due = soon) will be the first to run on that platform. We are currently testing it = and there are a few things we are a bit puzzled at. If anybody could give = some advice, we'd be very grateful.

The 2 biggest = problems we have so far are a memleak (I'll send another message with information on = that one) and a performance problem detailed in the message below, which I am forwarding as it seems it did not make it to the list. =

You can find kst = code under https://[user]@svn.kde.org/home/kde/branches/work/kst/portto4/kst (of course also available with anonymous svn, though not from behind a = proxy…), as far as I know it currently requires any Qt 4 version (not necessarily = the latest).

Kst 1.x was a = KDE application, but kst 2.x is so far pure Qt (.pro based), though an = optional KDE integration is planned down the road. I hope that still qualifies it to = be discussed on this list J

Don't hesitate = to ask for more information if needed,

Best = regards,

Nicolas

Betreff: Huge performance = problem under Windows

Hi,

I had used kst windows so far on fairly small = files. I had the impression it was slower than the Linux version but it was = only subjective. I tried to load gyrodata.dat from the SVN repos today to = show off the performance to a colleague. Well, it turns out it was a bad idea = L: it takes *ages* to load (I'm talking about = minutes here, don't discourage it will eventually appear !). I have no idea = where the difference comes from, loading the same file under Linux with the same = version (svn HEAD) is *instantaneous*.

Maybe the KDE-Windows folks could help there? = There must be a stupid reason. I tried the kst 2.0.0 beta from the website (I = believe it was compiled with VC++) and todays's SVN compiled qith Qt SDK = (Creator) 2009.02. This is to me a blocking point for widespread use on = Windows…
