[PyQt] PyQt book Rapid GUI Programming with Python and Qt now available

2007-10-23 Thread Mark Summerfield 
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.

(Note for Safari readers: The printed version of the book uses the PDF I
supplied as is, with fonts and typesetting exactly as I wanted them,
whereas the Safari online edition was retypeset by the publisher.)

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).

Regards,
Miguel Angel.

[PyQt] identify a QTreeWidgetItem

2007-10-23 Thread alteo_gange 
Hi everybody! 
 
I have created several QTreeWidgetItem and connected a 
signal itemClicked(QTreeWidgetItem *,int) on the QTreeWidget.:
 
 
 treeWidget=QtGui.QTreeWidget(widget) 
 ... 
 itemTree1=QtGui.QTreeWidgetItem(treeWidget) 
 ... 
 itemTree2=QtGui.QTreeWidgetItem(treeWidget) 
 ... 
 self.connect(treeWidget,QtCore.SIGNAL(itemClicked(QTreeWidgetItem 
*,int)),self.function) 
 ... 
 def function(self, item): 
 print item 
 
 
'print item' return: 
PyQt4.QtGui.QTreeWidgetItem object at 0x82cf62c. 
 
 
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.

[PyQt] NotImplementedError

2007-10-23 Thread Heinz A. Preisig 
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. The procedure has been working before, but
obviously I disturbed the devil.

Any suggestions on what to change or do to get rid of the problem

Cheers, Heinz

I'm sorry for the multiple messages.
Few subscription problems. Now, it's OK.

Excuse in advance for my bad english.

Thank you very much Mark for your book . I'm going to command it as
soon as possible (but it seems to me your book will be accessible in
France only at the end of november).

a+ ;)

 I don't know.

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]
...
