[PyQt] RegExp and QString
Hi,
Following Assistant (for C++) documentation about QString split method I
saw:
str = Now: this sentence fragment.;
list = str.split(QRegExp(\\b));
// list: [ , Now, : , this, , sentence, , fragment, . ]
Now, I with python I tried, a simple example:
line = p.readline()
sline = line.split(QtCore.QRegExp([A-Z]+))
With this code I got: TypeError: PyQt expected a character buffer object.
I don't know how to fix it, if I try a delimiter just line.slipt(',') it
works.
Some ideas?

I assume that str is declared as a QString.

Now, I with python I tried, a simple example:
line = p.readline()
So line is a Python string, not a QString.

Because a Python string knows nothing about QRegExp.

Convert the result of readline() to a QString...
line = QtCore.QString(p.readline())

Re: [PyQt] A couple of question about PyKDE4
Jim Bublitz wrote: Before I start out with PyKDE4, I have a couple of questions: - what is the preferred build system? cmake or configure.py? Will any of these build system vanish in the future? I haven't looked lately, but I think Simon is using cmake with the KDE SVN version. I'll be continuing to use configure.py. I'm pretty sure Simon will want to go with/stay with cmake, and that I'll stay with the configure.py setup. cmake support is needed to make it possible for people to build the whole kde-bindings module in one (big) go. I've also pulled out parts of that cmake code and made it possible to install PyKDE programs with it. Using cmake for a Python program means you also get access to the existing cmake support for building other KDE related things like translation (.po) files, docs, and C++ modules if you want to do mixed development. - are you going to make separate releases of PyKDE4, or will everything be coordinated with the KDE releases? I'll probably do separate releases - I'm behind again and won't be releasing for a month or two. If you are adding bug fixes to the KDE 4.0, then you could probably just skip the extra releases and just release via KDE SVN. KDE bug fix releases come out once a month these days, and we don't even have to lift a finger for that to happen. ;-) There's also a better set of documentation and a documentation viewer (pykdedocs) that integrates tutorials, example programs, docs and will let you browse other docs (Python, PyQt, Qt, KDE, etc) locally or online. The Ply-based tools will make it a lot easier to develop docs from the KDE doc set and is a much easier to maintain bunch of code. Once the docs are updated, and if the viewer is stable/complete enough, then we can put it in KDE 4.1. The only thing missing in PyKDE4 is Phonon support, which is a little messy (or was last time I looked). IIRC, Phonon will be moving into Qt itself, possibly in Qt 4.4. In which case it'll become Phil's problem. ;-) cheers, -- Simon Edwards | KDE-NL, Guidance tools, Guarddog Firewall [EMAIL PROTECTED] | http://www.simonzone.com/software/ Nijmegen, The Netherlands | ZooTV?

[PyQt] Model/View with multiple thread
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hallo everyone, I've started working with the Model/View concept and have some questions on implementing it in a multithreading environment. I hope that some of you have some ideas or advice on that and I'll highly appreciate any! So that's the basic structure: I'm working on an application that's processing data in a spreadsheet class. All processing in done in a separate thread and communicates with the GUI thread through multiple signals and slots. I now implemented a model in the GUI thread handling the exact same spreadsheet object, since the Model and View have to live in the same thread (is that right?). Thinking about how to keep the spreadsheet objects in worker and main thread synchronised I came up with two ideas: 1. Using signals and slots in both the worker and the model to update their spreadsheet objects whenever the other one changes. 2. Using a thread-safe singleton of the model to handle one single instance of the spreadsheet that are used in both threads. What would be considered a 'better' solution? Is there any other alternative that might work even better? I really appreciate any thoughts on this. Thanks in advance.
