I am not sure if this is the intended behavior, but if I subclass a QWidget
instance, and then try to connect to one of those signals in my subclass, I
get a TypeError:
>>> class MyLabel(QtGui.QLabel):
... def __init__(self):
... self.linkActivated.connect(self._lnkActivated)

No, the statements to the remote server take 20x longer!

You say similar dataset, just wondering if maybe the remote was missing
a index or hasn't been vacuumed in a while. Can you do a vacuum yourself
just to double check

Same happening on Linux with the same PyQt/Qt combination.

Hi Nick,
I'm trying to make it work without luck, is there any python example?
The example that is in *Rapid GUI Programming With Python and Qt* is only
for stackedwidgets.
Thank you.

The Qt docs refer to PSQL connection options and demonstrate the

Thanks for the suggestion. I was hoping to find a global parameter
(buffer_size, or similar) that could be tweaked to improve overall
performance.

Hi,
I have found an oddity with dbus and pyqt. A message of type string longer
than 120k sent over dbus will work, but the eventloop from where it was sent
will go crazy with cpu usage at 100% after that. This does not happen with
the glib eventloop and python, and it also doesn't happen with the

Perhaps time each part to see what exactly is taking up the time? One
way to do so is below:
t=time.time()
dostuff()
print "dostuff() time = "+str(time.time()-t)+" s"
Is it really the initial connection that takes a long time to get, or is
it something else on that remote machine. work_mem has no

I have a very simple program:
from PyQt4 import QtGui, QtCore
import sys
class Win(QtGui.QWidget):
SaveFiles = QtCore.pyqtSignal()
def __init__(self,parent=None):
QtGui.QWidget.__init__(self,parent)

It seems like subclasses of QSortFilterProxyModel will not emit
inherited signals. Tested with PyQt 4.7 / Qt 4.6.1 on Windows XP. I
couldn't find any related entry in Qt bugtracker, so I guess it's
PyQt's fault (unless I've done something wrong).
Here's a simple testcase (expects a ui.py file with

Oops. I didn't realize that that's a excpected behav
Take a look at a QStackedLayout.. You can add multiple widgets, each having
their own layout, to it and set it as the central widget of your mainwindow.
There's no need for deleting a layout and set a new one, since you alternate
between the added widgets / layouts.

Dear All,
I tried configuring with --debug on OS X 10.6 with sip 4.10.1/PyQt
4.7.2, Qt 4.6.2 (built from source)
The linker tries to pull in -framework QtCore_debug. This does not
exist. -lQtCore_debug could possibly work with libtool, I guess?
