Hi,
I am observing an issue disconnecting a signal using the new style signal-
slots API. If the signal to be disconnected is not connected, I am getting a
TypeError exception. Using the old style API, the code silently ignores the
disconnect. The little script in the attachment shows the issue by commenting
the various lines in the disconnect_method method. Is there a method to check,
if a signal-slot connection has been established (e.g.
mySignal.isConnected(slot) )?
Regards,
Detlev
