Re: [Boost-users] [signals] call a slot only once

Nevermind,
I'll just keep a vector<connection> in a signal-derived class, and
disconnects these after every invocation of the signal. Maybe not the most
clever way, but it works.

If there is an efficient way of doing this, I'll be happy to now about it
though.

Thanks,
Christian
