Printing non-ascii characters.

Hi,

after a quest for connecting to an odbc data source and after much documentation reading, i finally have a snippet that i can connect and execute a parameterized stored procedure! :)

The sp is a simple one, getting an integer and returning one colymn of string data

The only 2 questions i have is that if i HAVE to declare the stored procedure parameter type as QVariant(4) or is another way to do this,
and (more important) how i can print non-ascii data that exists in the result set...

I am using Eclipse/PyDev (if that matters) but i print garbage from the snipet below,
and am not sure if the i correctly coded the part about QVariant.toString and QtCore.QString.toUtf8(candidate). (i am propably not...)

In a real app would put the data in a grid but what about now ?? I check the variable"candidate" in the debugger and it correctly contains the Greek characters that came from the database, but how i can...print them ??:confused:
Is there something in Qt that i am not doing (or at all...) correcltly ?


Code is below:

Code:

---

# -*- coding: utf-8 -*-
 
import sys
from PyQt4 import QtCore, QtSql, QtGui
 
app = QtGui.QApplication(sys.argv)
db = QtSql.QSqlDatabase.addDatabase("QODBC");
db.setDatabaseName("pm");
f = db.open()
 
if f:
    print "Connected"
    query = QtSql.QSqlQuery(db)
    query.prepare("{call graduation_fetch(?)}")
    query.setForwardOnly(True)
    query.bindValue(0, QtCore.QVariant(4), QtSql.QSql.In)
    query.exec_()
 
    while query.next():
        candidate = QtCore.QVariant.toString(query.value(0))
        print QtCore.QString.toUtf8(candidate)
 
    db.close()

---

and of course, thanks for any help!

It should be:

Code:

---

while query.next():
        candidate = query.value(0).toString()
        print candidate.toUtf8()

---

but those strings will be displayed correctly only if your console uses UTF-8. You might try toAscii() or toLocal8Bit() instead.

Hmm...so, i correctly did not like that QVariant stuff, but i use Python as you already know so the back-and-forth of the C++ documentations is not every time so straightforward ;)

Thanks a lot! That toLocal8Bit() did the trick! The Greek names are now correctly displayed to the Console Window.

So, i already did a form by using the Qt Designer and i can display the same data to a listWidget.

Thanks again! :)
