Re: [Boost-users] Using boost.signals with boost.bind

I have one problem with boost.bind and boost.signals I can't understand.

I have used bind with signals in a simpler way than you have in this example. It works well for me. I don't know if you are doing it in a more complex way for a reason, but hopefully my simple version will be some help. class MyClass { public: MyClass(void) { // define the connection using bind mySignal.connect( boost::bind(&MyClass::MySlot,this,_1)); } boost::signal mySignal; private: void MySlot(bool state) { // do something here to process the signal data when this is called } }; // later on, to call that signal inst = MyClass(); inst.mySignal(1); This is all pretty straightforward. This only unusual thing (for me) is the use of _1 as a marker for the first parameter. If you have a function with more parameters, then the next parameter would be _2 and so on.
