I've installed Python2.6 and PyQt-Py2.6
Running the same program that works with PyQt-Py2.5, now using QMYSQL
driver, I've got the following error:
connection 'qt_sql_default_connection' is still in use, all queries
will cease to work
Any idea ?
PD: Sorry Phil, it was that gmail's replying
Thanks for replies. First i'd like to make sure if that''s the normal
behavior or not. Can you confirm please ?
** To David **
Here you get the error string after execution!
Sorry, the order of the lines is:
errorstr = str(query.lastError().text())
query.exec_()
But the problem is there.

I guess Eric is a complex application, and Python is not the best option to
write applications to run fast (Eric is written in Python as you probably know).
I don't like Eric for that reason. Use kate or a better editor, VIM ;-)
Good luck

Hi there
I'm starting with a pyqt development, a database application (what original).
I can't decide which datatypes and sql library to use. I mean, is it

If i use python datatypes, using pyqt4-sql to access data

Hi there
I'm doing a dialog with a sql data form and it's OK/Cancel buttons.
The data is managed with model/mapper
I connect the button's cancel.clicked() signal to a method that
reverts changes, quits editing mode,
and do more things like enabling some widgets back. Call that method 'rollback'.
I'm isolating my problem with mapper.
When i setup a mapper, the ESC key reverts changes in the edited widgets.
That's ok, but i need to trap that situation. I need to do more than
revert changes
when i press ESC.
For instance, before going into editing mode i disable some buttons.
When i press

self.layout.addWidget(child)
Now, can i reference a Framework's widget from a Form's instance

Hi, i'm using pytq4 + designer4.
I want to design a generic main window with common buttons (next,

Hi there, i'm developing an application under Linux, where i can use
the mysql driver.
But if i want that app to run in Windows too, there PyQt do not have

functions, could that app run in linux

Hi, now i know that with eric4 i must use the 'Generate Dialog Code'
