PyQT installation /configuration

[adrian_p_smith]

Hi there. I've been trying to get PyQT working on W2K, but have not yet
found a sufficiently detailed walk-through for my somewhat
command-line-challenged sensibilities. I did find this page:
http://www.diotavelli.net/PyQtWiki/GPLPyQtWindows , but I'm not sure
about installing the whole of Visual Studio .NET as a prerequisite. Can
anyone tell me if the passing of the years has made this process any
more approachable?

For Qt4 use the binary installer from...

For PyQt4 use the binary installer from...

Ah thanks, I'm a dork. Why didn't I see that before <mutter>?

Waitaminute, didn't you write it? Oh dear.

I've got another problem, I'm afraid - I've installed Qt 4.1.4 and PyQt
GPL v4.0 over Python 2.4, and the demos for both run happily enough,
but when I try to run the first example (in IDLE) from Boudewijn
Rempt's GUI Programming with Python: QT Edition I just get
"ImportError: No module named qt". Is there something I need to add to
my sys.path here?

Sorry to bother you with the newbie questions.

The module structures for PyQt3 and PyQt4 are quite different: the
monolithic qt module from PyQt3 has been replaced by a number of
modules in PyQt4. Despite this, there is a similar way to "import qt"
in PyQt4:

from PyQt4 import Qt

However, you will have difficulty using the examples in that book
because it was written for PyQt3. Work is underway to "port" the book
to PyQt4, but it will take some time. (You can help with this and learn
about PyQt4 at the same time, if you want.)

In the meantime, the set of slides from a talk at EuroPython 2006 is
probably the only learning material on the web for PyQt4:

http://indico.cern.ch/contributionDisplay.py?contribId=33&amp;sessionId=41&amp;confId=44

There's plenty of learning material for Qt 4; the official
documentation at http://doc.trolltech.com/4.1 contains examples
and overviews that are readable if you already know C++. Those of us
who use PyQt4 are still catching up!

All the best,

David

Ah yes, it doesn't recognise "QApplication" now. Never mind.

Er...you might be overestimating my potential unless there's some
*really* entry-level material to be dealt with there. Though they do
say it's a good way to learn. Is there a forum?

One of the reasons I chose Python was so I wouldn't have to, alas.

Thanks!

Boudewijn's book describes Qt/PyQt v3.

QApplication is still there. You can access it via the Qt module and
create an application object in the following way:

import sys
from PyQt4 import Qt
app = Qt.QApplication(sys.argv)

Yes, it's at http://mats.imk.fraunhofer.de/mailman/listinfo/pykde

Much of the example code for Qt is readable even if you only
know Python. Some of the main differences between Qt and PyQt
are described in this document:

Good luck!
