[PyQt] Drag and Drop when using designer
Hi! I've made all my gui with designer. I have some List Views there that need drag and drop funcitonality so I need to add them some methods to handle the drop events properly, and set the accept drops to True... but I can't add those methods with setattr, they don't work, it seems I have to subclass the List Views. Is there any way to get the drop thing without altering the set up that setupUi method does?

The book is a hardback, 648 pages, ISBN 0132354187. The foreword was written by Phil Thompson (creator of PyQt), who was also one of the book's five technical reviewers. For a brief overview of the book and the table of contents, etc., see http://www.qtrac.eu/pyqtbook.html This web page also has links to places that sell the book, and has the full source code for the examples (and model answers to almost every exercise) available for downloading. The book covers PyQt4 (it has no coverage of PyQt3), and is best used with Python 2.5 and PyQt 4.2 or better, on Windows, Mac OS X, or an X11-based Unix or Linux. No prior knowledge of GUI programming is assumed, so don't worry if you've only ever done web programming:-) Since this is the only book that covers PyQt4 it is automatically the best---but I have not been complacent, and have worked extremely hard to make the book as accessible, useful, enjoyable, and interesting as possible.

The puzzle example indicates however that you don't need to change the listviews, only the underlying model which needs to provide mimeData and dropMimeData and probably also mimeTypes. Then you just need to enable the drag/drop on the listviews by setting their dnd properties to true. Is there any way to get the drop thing without altering the set up that setupUi method does? You should never try to alter the generated code. If a subclass is really needed you should create a new widget class and use the promoting feature to have code generated that uses your new widget. See the designer documentation for how that works. Andreas -- Future looks spotty.

[PyQt] qimage.sip, Lower bound is not a time version
Dear pyqt people,
I am having a problem with pyqt/sip doing what I think is quite a

I get the error

There are none in Qt itself, except for the QStandardItemModel which allows to build tree's, but of course is not that suitable if you have legacy code that you want to wrap in Qt. I mean building a tree model using QAbstractItemModel for a QTreeView. It is one of the tasks in Qt that is not for the faint of heart. The need to manually fiddle with index() and parent() is a mess. I've never understood why the model requires you to provide a two way access system to the data, ie why do you have to be able to tell both the cildren of a given node *and* its parent? The first is obvious, the latter is something I think Qt should take care of internally. I don't find the creation of a tree model really problematic, I guess if you want an answer to that question you should contact qt-interest list or TT directly. I suspect that this is not an artificial requirement, but actually needed for the stuff to work. As it is now most apps likely read in data to some custom data structures, say, lists of lists or similar. You are then more or less required to duplicate this own tree into another structure so that you can add in the stuff Qt needs. See the standard Qt Simple Tree example for an example of the extra datastructure that is required. Thats not correct. The tree model reads some input data and creates a tree from that. The input data is discarded after the building of the tree. You don't always need an intermediate special tree-like structure to build a Qt model on top of some legacy data, it depends on the structure of your legacy data. What is IMHO missing there is a QAbstractTreeModel that removes most of the gore (such as parent()) and leaves only the relevant pieces for the applications developer to worry about. This doesn't work, because parent() is different in almost any tree model. For both list and table view its easy, because parent always returns QModelIndex(), the same with index, all it has to do is create a model index with the given row+number, it doesn't need to care about the given parent.

Btw, Mark: congrats on your new book! I'm sure it will really be helpful for us trying to learn and teach PyQt. I will try to source it here and recommend it to my students, friends and colleagues.

[PyQt] segmentation fault
Hi all, i am new to PyQt an QT as well. I just downloaded and installed Qt 4.3.2 and PyQt 4.3.1 from source on my Debian based sidux machine. Everything configured and compiled just fine. All qt examples are working but if I try the PyQt examples, I always get an segmentatin fault. Any ideas ? Thanks for any help Reinhard ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Backtrace of a debug build would help us enormously, but why don't you sue some slightly older, but ready to be used debian packages. Compiling the stuff yourself is doable, but requires some distribution specific knowledge of these package builds. Generally, build from tar balls requires you to be even more sensible about what is installed with the rest of the system, e.g.: probably you have two Qt4 libs installed now in different paths: perfect recipe for hard to track down disaster.. If you still want to build the stuff, build deb packages, based on already available ones. You will learn a lot from that task, and it will pay off on the second install (on a hopefully similar system to the build host). Good luck, Pete No: I don't have/use any debs handy since I'm addicted to rpms. You will imagine why, when you start building debs on your own.. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

I could find it quite a bit cheaper at libri.de, its 42,74 euro there, which is still more than 10 dollar more than the original price from prentice hall. If I buy directly from prentice hall, I'd pay 67$ including shipping, AFAICS I thought I'd see if I could find a lower price in the Euro zone, or a price outside that would correspond to a lower price. I used kelkoo.co.uk first, then tried their service in other regions. Here's what I found: United Kingdom: 23.75 GBP (~34 EUR) http://books.theregister.co.uk/catalog/browse.asp?ref=863830 Apparently, shipping would be free if the price was over 25 GBP. :-( Otherwise, it appears that delivery to Europe is 7.95 GBP (~11 EUR)! (http://books.theregister.co.uk/info/payment_delivery.asp) Norway: 297 NOK (~38 EUR) http://www.capris.no/product.aspx?isbn=0132354187 Shipping appears to be free (within Norway, I suppose), but that may depend on my interpretation of the word fraktfritt! (http://www.capris.no/customerservice.aspx) The first price shouldn't include any tax. I'm not certain what the situation is with tax on books in Norway, so I don't know if the price is inclusive of tax or not. I think it makes sense to look around for the best price, but I guess I don't understand the complaining about the price. I've got a copy of Stroustrup's C++ Programming Language that cost me $65 probably 5 years ago or more. I don't use it much, but the binding is falling apart, and it's not even a language I like. And considering what my daughter pays for college textbooks (actually what I pay for her books), Mark's book seems pretty reasonably priced - this isn't going to make the bestseller lists (no reflection on Mark - there just aren't that many PyQt users, although I've heard the plot is weak too), or even sell as many copies as the average college text. Considering we get free software that actually works and free, fast online support from the author of the software and the author of the book and the lead tech writer at TrollTech plus the other really knowledgeable people on this list, it doesn't seem to me that the price is that bad when you take all that into account. I can sympathize with people who have a hard time coming up that amount of money - I've been there. But then again, esp considering the Windows users who fork out a lot of money to Microsoft for software with less quality and support (even if it came 'free' with your computer) - I guess I don't think it's that bad to send less money than the price of Windows to Mark and someone willing to publish him. He can probably make better use of the money than Bill Gates. (I'd say less than Linux too, but I've been buying distros at CheapBytes, and most of you probably download). Divide the cost of the book by 4 for Qt, PyQt, Python and the book itself, and the price doesn't look too bad at all. Just my 2 cents - (and if I post enough of these you can cash them in and buy the book - but do it before the dollar falls even more). Now I have to go remove the cat from the microwave ...

I just wanted to show that there are good deals to be found if you want (or need) to shop around. I found it quite amusing that one of the best deals was from a bookseller in one of the world's most expensive countries. :-) I've got a copy of Stroustrup's C++ Programming Language that cost me $65 probably 5 years ago or more.

Maybe not. However, even as an experienced Python programmer, I found the introduction to Python worth reading - and I was very sceptical about the need to include it in the book at all. (Apparently, publishers believe that books about Python need to tell the reader how to use the language no matter what level they're aimed at!) Considering we get free software that actually works and free, fast online support from the author of the software and the author of the book and the lead tech writer at TrollTech plus the other really knowledgeable people on this list, it doesn't seem to me that the price is that bad when you take all that into account. Actually, I'm billing you for the time taken to write this message. ;-) Seriously, at over 550 pages, I think the book is well worth the retail price. For a book aimed at GUI programming, it covers a wide range of topics, and it deals with many of the fundamental concepts and techniques you need to know when using PyQt4. In addition, the appendix on installing PyQt looks like it addresses the usual questions people have, and I expect it was quite distracting and time-consuming to write. Note: As a reviewer, I received a copy free of charge, but I would have bought a copy anyway. I had to squeeze my reviewing duties in between work and real life, so I didn't really have the time to enjoy the book the first time around. :-) David ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Mostly on hardware, but one of my favorites was a text on BASIC for the PDP-11 (in the late 1980s - it was obvious PCs would dominate by then), with about half the book devoted to simulating logic gates in code. I was surprised the check cleared for that review. I'll probably pick up a copy just because there are some things in Qt4 I still haven't found time to get on top of, and some bad habits I should probably break.
