I attach the .svg too.
in the svg (and the png), i wrote hello in arial/40
why should I scale the text (with a ratio of .75) to get a correct size ?

For me the 2 texts are sized equal if I remove the line, which scales the
text.
But I guess I do not have the font Norasi (rendered as some

[PyQt] QSqlTableModel.rowCount bug? (and still need infor for beforeInsert)
Hi all!
I suspect QSqlTableModel.rowCount cannot return numbers above 256.
For this finding could somebody please write me a mini-example of the
QSqlTableModel.beforeInsert?
Look, this outputs 256 for me (python 3.1.2, pyqt 4.8.1, XP SP3)
And can somebody tell me why this code is this painfully slooow?
import sys
from PyQt4.QtCore import *
from PyQt4.QtSql import *
from PyQt4.QtGui import *
app = QApplication(sys.argv)
db = QSqlDatabase.addDatabase(QSQLITE)
db.setDatabaseName('test.db')
db.open()
query = QSqlQuery('CREATE TABLE preferences (id INTEGER PRIMARY
KEY AUTOINCREMENT NOT NULL, value varchar)')
model = QSqlTableModel(db=db)
model.setTable('preferences')
model.select()
for i in range(300):
record = model.record()
record.setValue('value', str(i))
res = model.insertRecord(-1, record)
model.submitAll()
print(model.rowCount())
del model, db

[PyQt] QSqlTableModel.beforeInsert signal (new style signal/slot)
Hi!
I am trying to connect the beforeInsert signal of a QSqlTableModel,
and having some problems.
I've found this similar thread:
http://www.mail-archive.com/pyqt@riverbankcomputing.com/msg20117.html
However, I am using pyqt with py3k, so I prefer the new style signal
and slots, but I appreciate any working solution...
So my attempt based on the thread:
class BatteryMain(base_class, form_class):
# ...
def cycle_started(self, record):
print(Inserting {!r}.format(record))
def battery_load(self, filename):
self.cycles_model = QSqlTableModel(db=self.battery_db)
self.connect(self.cycles_model,
SIGNAL(beforeInsert(QSqlRecord
)), self.cycle_started)
RESULT:
QObject::connect: Cannot queue arguments of type 'QSqlRecord'
(Make sure 'QSqlRecord' is registered using qRegisterMetaType().)
Another attempt with new style signals and slots:
class BatteryMain(base_class, form_class):
# ...
@pyqtSlot('QSqlRecord ')
def cycle_started(self, record):
print(Inserting {!r}.format(record))
def battery_load(self, filename):
self.cycles_model = QSqlTableModel(db=self.battery_db)
self.cycles_model.beforeInsert.connect(self.cycle_started)

File D:\prg\biQazo\biQazo.py, line 145, in battery_load
self.cycles_model.beforeInsert.connect(self.cycle_started)
TypeError: connect() failed between beforeInsert(QSqlRecord) and unislot()
Could anybody tell me the correct syntax, please?

[PyQt] QSqlTableModel without view
[sorry for the posting more messages, but I figured out now, that my
subscription address was wrong, and I got no error message from the list,
that my messages will not appear :(]
Hi!
I am a novice pyqt developer.
I will develop a pyqt program, which will periodically will get
measurement data, and display it visually. That's why I have chosen to
store it in sqlite database. Measurements have some metadata, so I
thought they should also go to the same db, in an ini like table
(table name preferences, key and value are strings).
I have written 2 classes for that, but that does not seems like a
straighforward solution... I hope there is a cleaner and more
efficient way...
class BatteryDb(QSqlDatabase):
@classmethod
def addSqlDb(cls, filename=None):
db = QSqlDatabase.addDatabase(QSQLITE, 'battery')
# if filename is None FIXME
db.setDatabaseName(filename)
db.open()
return db
@classmethod
def removeSqlDb(cls, db):
print(battery db delete)
db.close()
QSqlDatabase.removeDatabase('battery')
class IniTable:
def __init__(self, db, table, parent=None):
self.model = QSqlTableModel(parent, db)
self.model.setTable(table)
self.model.setEditStrategy(QSqlTableModel.OnManualSubmit)
self.db = db
self.model.select()
self.build_indices()
def build_indices(self):
self.indices = {}
for i in range(self.model.rowCount()):
self.indices[self.model.record(i).value('key')] = i
def __getitem__(self, attr):
return self.model.record(self.indices[attr]).value('value')
def __setitem__(self, attr, value):
if attr in self.indices:
idx = self.indices[attr]
record = self.model.record(idx)
record.setValue('value', value)
self.model.setRecord(idx, record)
# idx = self.model.createIndex(self.indices[attr],
self.model.fieldIndex('value'))
#self.model.setData(idx, value)
else:
record = self.model.record()
record.setValue('key', attr)
record.setValue('value', value)
res = self.model.insertRecord(-1, record)
#self.build_indices()

It's not a syntax problem.
Are you using threads?
Yes, I am using threads. Is it valid to insert into a QSqlTableModel a new
row in a QThread?
I have a worker thread, which collects data, and inserts it into the
QSqlTableModel, and I'd like to get notified with this beforeInsert signal
in the GUI thread.
I would guess that you can't use signals that take a QSqlRecord across
threads, probably because they are not passed as const (to allow them to be
updated by a connected slot).
That sounds sad. I thought this signal will make it easy to communicate
between threads.
Then what is the solution to communicate between the worker thread, and the
main GUI thread? Cutsom signal?
thanks
Gergo
