Hi netog,
While I really haven't used PyQT/Python with MySQL in any of my little projects,
as I understand, you will be using PyQT more for creating the widgets and Screens, butt the real interaction with MySQL and creating and executing queries will be essentially a Python-MySQL communication.
So maybe you should google Python and Mysql for more info.
Examlple :
http://dustman.net/andy/python/python-and-mysqlThis link does show a lot of the methods to use the Python DB-API to interact with MySQL. Hope that helps.
Ther are a lot of qidgets which are not included in PyQT - notable being the Splitter widget. I think there was a list somewhere which had a comprehensive list - most probebly from Trolltech itself.
(oh, but maybe that was for widgets in QT, but not in Qtopia (the Zaurus package of QT)).
