It's a SIP code generation bug. It's fixed in hg and tonight's snapshot.

[PyQt] QApplication.saveStateRequest does not work well with PyQt 4.8

2011-05-20 Thread Wilbert Berendsen 
Hi,

In my application ("frescobaldi") (using API 2 for QString and QVariant),
if qApp is an QApplication(),

def saveState(sm):
pass # code saving state

qApp.saveStateRequest.connect(saveState)

yields:

Object::connect: No such signal
QApplication::saveStateRequest(QSessionManager)
Object::connect:  (sender name:   'frescobaldi')
Traceback (most recent call last):
  File "./frescobaldi", line 2, in 
import frescobaldi_app.main
  File "/home/fede/src/frescobaldi/frescobaldi_app/main.py", line 41, in

import session  # Initialize QSessionManager support
  File "/home/fede/src/frescobaldi/frescobaldi_app/session.py", line
100, in 
app.qApp.saveStateRequest.connect(saveState)
TypeError: connect() failed between saveStateRequest(QSessionManager)
and unislot()

So, first QApplication complains, and then PyQt4 errors out.

On PyQt 4.7 this works well.

On PyQt4.8 the old way of connecting does work, however:

QObject.connect(qApp, SIGNAL("saveStateRequest(QSessionManager&)"), saveState)

does work correctly on both PyQt versions (4.7 and 4.8).

Is this intended?

with many regards,
Wilbert Berendsen
