Hi and welcome to devnet,

It's rather that you are giving the slot a parameter. You also can't connect a parameterless signal to a slot with parameter.

Anyway, for your purpose the use of a lambda is perfectly fine

Now even better. I've found that calling toUtf8() turns the unicode array implicit in the QString passed by the original @pyqtSlot decorator into something which can be written to file without messing about, and which preserves special characters. I've no idea why no combination of python str() and bytearray() encode and decode operations could seem to achieve this, but it's done now...

This was the result of two interlocking features of the tools I was using.

First of all PDB breakpoints seem to be locked to the thread they were inserted from. Consequently, because the QT Eventing thread was the one triggering the update, PDB wasn't able to detect the invocation.

Secondly, QXMLQuery seems to have inbuilt caching, meaning that changes to focus and query files had no impact on the second invocation of evaluateToString()

Between these two features, it meant that I was unaware that update WAS in fact being called. After building a minimal test case, I was able to track down the problems.

Python's None type represents null values.

Hi and welcome to devnet,

Might be a silly question but did you indent your source correctly ? The code you posted shows that setA is not part of Window since it's at the same level as e.g. main

No it doesn't lack, you have all the building blocks to do it yourself. Have a look at QTreeView, QFileSystemModel etc.

Seems PySide only supports sqlite so far:

Not sure where the documentation for this is.

Hi,
you do not need the lines
@
query.first()
codeToParseRecord()
@

simply start with query.exec():

@
query = QSqlQuery("SELECT Blahblah, Blippity, Bloop FROM Floozle ORDER BY Bloop")

if (query.exec()) {
while query.next():
codeToParseRecord()
}
@

It works (an helps :) ), thank uou.

Hi,

Since the symbol is not found you are missing a library in your LIBS line

In the case of a standard use of your computer, you'll probably already have several copies of Qt depending on what application you installed.

While developing the problem doesn't occur if you use e.g. Qt Creator since it modifies the environment as needed for your application to run.

You can try the pyside IRC channel or mailing list :)

Thanks for the response -- I'll have to do some translating to PySideify it but I think that's doable. I'll post back if I'm still confused.

Thanks!
