[PyQt] chain signals, disconnecting an "emit" slot

[Pierre-Louis Bonicoli]

Hi,

I encounter a problem using "emit" method of a signal as a slot of
another signal. Problem occurs using "disconnect".

Here is sample code, 'ok' and 'cancel' inherit from QAbstractButton:

ok.pressed.connect(cancel.pressed.emit)
ok.pressed.disconnect(cancel.pressed.emit)

The second statement raise an exception:
"TypeError: 'builtin_function_or_method' object is not connected"

Calling "disconnect" without parameter works fine.

If I use an intermediate function, TypeError is not raised:

def reemit():
    cancel.pressed.emit()

ok.pressed.connect(reemit)
ok.pressed.disconnect(reemit)

Behaviour is the same with old style signals.

Is there a way to not use an intermediate function ?

sip: 4.12.4
PyQt: 4.8.3
Qt: 4.7.3

Test cases in attachment.

Thanks,

Pierre-Louis
