[PyQt] Project on PyQt

[Hans-Peter Jansen]

Hi Claudio,

first of all, a warmth welcome to PyQt and please beg my pardon of replying 
this late. It's a bit of a shame, that your message has kept unanswered this 
long...

I'm attending this forum since a long time, well 2001 to be honest, and it's 
been a mailing list with one of the highest signal/noise ratios out there, 
that I've ever seen. That's mostly due to Phil himself, who is a real master 
in this respect (up to the point, where conciseness starts to hurt. In the 
most salutary way, of course ;).

Congrats for your choice. It's hard to express the power of this magnificent 
environment is a few words. You will not get more bang for the buck anywhere 
else in the Python GUI world. Explore the Qt docs, and remember, that _all_ 
this is at your fingertips, but without all this C++ cruft. You need to learn 
to ignore these parts.

Of course, this comes with a price. The overwhelming functionality takes some 
time to become familiar, and the PyQt binding cannot always cover its origins. 
On the other hand, it tries hard to pass on Qts efficiency to the user.

For anything else, I'm implying, that you will take the PyQt5 route with 
Python3. In order to get started, I still recommend Mark Summerfields book 
"Rapid GUI Programming with Python and Qt". While still based on Python2 and 
PyQt4, it is a fantastic read for the general GUI and specific Qt concepts. 
The major differences to the actual state of affairs are somewhat neglectible, 
if you're fluent with Python itself, and the Python2 to Python3 transitioning 
hiccups in particular. The examples are available for Python3 (and PyQt4) at 
least.

In fact, with Python3 and PyQt5, things got a lot easier again. Phil does a 
great job in eliminating the dreaded QStrings and QVariants, so this 
harmonizes perfectly with Python3 unicode strings. You might want to try eric, 
the IDE, that is written in PyQt. It helps beginners with the loose ends like 
designer and translation integration, for example.

After/During reading Marks book, study the examples, that come with PyQt5.
If you're stuck at some point, try to reduce the issue to the simplest 
possible implementation. Usually, you will solve it in this process. If not, 
don't hesitate and post your issue here.

General advices are a bit harder to harvest in mailing lists (and the web), as 
you see with this post, but possible anyway.

Good luck.
