I have lots of problems using Python functions as slots. As a simple
illustration, take the following code (an example from Boudewijn Rempt's
excellent book with an added connect):
import sys
from qt import *
def foo(*args):
print args
app=QApplication(sys.argv)
button=QPushButton("Hello World", None)
app.setMainWidget(button)
button.show()
app.connect(button, SIGNAL("clicked()"), app, foo)
app.exec_loop()
When I run this code, I get:
Traceback (most recent call last):
File "hello1.py", line 14, in ?
app.connect(button, SIGNAL("clicked()"), app, foo)
TypeError: Argument 4 of QObject.connect() has an invalid type
This doesn't always happen. For example, I can run the example
"dial.py" from the same book without problems, although it uses Python
methods as slots.
In case it matters, I use PyQt 3.4 and Qt 2.3.1.
Any idea what is happening here?
Konrad.
