I need these for a QSignalSpy, the full type name is actually
Imap::Mailbox::ImapTask*. The error message I get when using any of these is
the following:
Don't know how to handle 'ImapTask*', use qRegisterMetaType to register it.
The Imap::Mailbox::ImapTask class in question defines the signal with a
non-namespaced argument, i.e. like this:
signals:
void completed(ImapTask *task);
It looks that one has to use the identical signature in the SIGNAL macro as
what was used in the class' definition (otherwise one gets an error like
QSignalSpy: No such signal: 'completed(Imap::Mailbox::ImapTask*)').
And it also seems that the best approach is to always use the fully-namespaced
version everywhere, including the signal definition in the class' definition,
the qRegisterMetaType and the SIGNAL macro.
Cheers,
Jan
