[Signals2] Wrapper function for connecting slot won't compile
I have code similar to the following:
template<typename A>
class SomeClass
{
void memFunc(FileDescBase&) { ... }
};
template<typename B>
class OtherClass
{
void setOpenCallBack(boost::signals2::signal ::slot_type const& rOpenSlot)
{
mOpenSignal.connect(rOpenSlot);
} void setCallBacks()
{
SomeClass myClass;
setOpenCallBack(boost::bind(&SomeClass<B>::memFunc, &myClass)); //does
not compile
setOpenCallBack(boost::signals2::signal ::slot_type(&SomeClass<B>::memFunc, &myClass)); //does not compile either
}
boost::signals2::signal Even a direct call to mOpenSignal.connect(boost::signals2::signal
SomeClass myClass; setOpenCallBack(boost::bind(&SomeClass<B>::memFunc, &myClass)); //does not compile
Your memFun() has 1 argument, and you have express this in the bind: setOpenCallBack(boost::bind(&SomeClass<B>::memFunc, &myClass, _1));
Thanks. I always miss the simple things... ----- Original Message ----- From: Igor R [mailto:boost.lists@gmail.com] To: boost-users@lists.boost.org Sent: Mon, 06 Jul 2009 18:15:14 -0500 Subject: Re: [Boost-users] [Signals2] Wrapper function for connecting slot won't compile
