It means that PyQt development won't open up and become more community driven, that we (and other customers) still have to worry about the what-if-Phil-gets-hit-by-a-bus scenario, Is this the classic "What happens to my FOSS / closed source application if Riverbank disappears?" problem?

Re: [PyQt] PyQt Licensing
Hello, Phil Thompson wrote: In a nutshell, the PyQt licensing will not be changed in the short term. This is mainly a financial decision - I want to ensure that PyQt development, and that of other software, can still be funded. For the moment an least, making an LGPL version available would be too much of a risk - particularly as it would be impossible to reverse such a decision if it proved to be a mistake - but it is something that I will continually review. Thanks for the clarification. This is a position that I can understand and respect. There are at least a few people who would like to see a LGPL and supported SIP + PyQt, but realistically there are more like two options or outcomes: 1) Current situation with a supported and developed SIP + PyQt, or 2) LGPL SIP + PyQt but unsupported and undeveloped. I don't see a lot of people putting their hand up to do bindings development (see QtJambi). From a Free Software point of view, a support GPL SIP + PyQt is a lot more useful than an unsupported LGPL version. Closed source wise, I don't have a problem with the idea that you should pay for the tools that are helping you develop and make money with your own software. cheers, -- Simon Edwards | KDE-NL, Guidance tools, Guarddog Firewall si...@simonzone.com | http://www.simonzone.com/software/ Nijmegen, The Netherlands | "ZooTV?

You should put your icons in a resource file, compile it as a .py file, and import it as any other module.

[PyQt] possible threading/locking bug in PyQt4 snapshots
Hello,
I have attached a short script that I think demonstrates a bug in the PyQt4
snapshots. I expect the following output on the command line:
0
1
[...]
9998
complete
The script runs as expected with PyQt4-4.4.4 on 64bit Kubuntu Jaunty
(although I have to invoke ctrl-z to exit the script. I don't know how to
improve that part, but that is not the subject of this post.)
With the most recent (20090507) snapshots installed on 64bit Gentoo, the
script does not run to completion. The script usually hangs up before
anything is printed at the command line, although occasionally the thread
gets part way through the loop before it hangs up.

[PyQt] FetchMore Example - Table Edition
Hello Everyone,
The last time I wrote in I had presented the FetchMore example. I've
extended this example to use a simple table model. The input is a 2d
numpy array. I couldn't find an example with lazy table population
anywhere, so here's what I've got.
Feel free to use it as you wish. Hope that someone finds it useful.
Regards,
Darryl
