Signals and slots

Recommended Posts

Does anyone know of a *very* gentle introduction to implementing a signals and slots mechanism in c++. I've done a quick search around and found an overview, but no real specifics on how they work internally.

Gentle introductions? Not really. The most gentle you're going to get would be how to use existing signal and slot mechanisms, like boost::signals, not rolling your own. The problem is that a general purpose signals and slots mechanism in C++ tends to somewhat involved since C++ doesn't exactly present a sane function reference model. Ex: the result of the ->* operator can't be stored.

A good source for learning how to roll your own would be the book Modern C++ Design. It goes into detail on how to make a generalized callback mechanism.

Try looking into Qt..I use it professionally and it works quite well.
