It's very abstract!
I must identify QTreeWidgetItem in order to connect it an action (view a
widget on the right), but how? With a method of the item reference? Which?
I don't know.
With the .text() method, i can recover the QTreeWidgetItem name:
print item.text(0), "\n"
But with no-ascii characters (ex: itemTree.setText(0,_(u"Filtres vidéos"))),
there is an error:
Traceback (most recent call last):
File "/home/login/docs/langages/python/pyqt4/QTreeWidget.py", line 126, in
fonction
print item.text(0), "\n"
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position
11: ordinal not in range(128)
I find this one of the most annoying things in PyQt, it confuses me
terribly. I think in this case you can do (for example)
print unicode(item.text(0)), "\n"
(the original result from item.text() being a QString)
But it may be that you need to specify an encoding and use the
encode or decode methods of unicode or string ...

Store the items in a dict as you create them:
self.itemDict = {}
itemTree1=QtGui.QTreeWidgetItem(treeWidget)
self.itemDict [itemTree1] = ?? # could be the associated widget that you want
# to connect to, or a
# string identifier
itemTree2=QtGui.QTreeWidgetItem(treeWidget)
self.itemDict [itemTree2] = ??
...
def function (self, item):
widget = self.itemDict [item]
...

[PyQt] NotImplementedError
Title: business Hi, I have been expanding my code with new features after which I experience an error NotImplementedError: QGraphicsItem.boundingRect() is abstract and must be overridden when using the rubber band.

I recommend this book to anyone that wants to learn PyQt, it is a excellent book with many real world examples with working code and really new stuff (it even use import from future in python).

I bought the "rough cut" version via Safari - it is a true delight to read. Covers a very comprehensive cross section of PyQt4 - I can really recommend it highly to anybody beginning to program in PyQt4 >From my perspective however I'd wish the introductory chapter on general Python (which is excellent for real beginners btw, I get my kids to read them!) was scrapped in favour of more detailed widget discussion, or alternatively, just more pages.

[PyQt] PyQt book "Rapid GUI Programming with Python and Qt" now available
Hi, I am delighted to announce that "Rapid GUI Programming with Python and Qt: The Definitive Guide to PyQt Programming" has now been published in the US. 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.
