Event receiver programming

We would need a lot more information about what you are trying to do in order to offer any real help.

Until then, here are a couple of potentially useful links:

The Observer pattern
Boost.Signals

erm... essentially i wanna make something like the irrlicht event handler for example.. and i have no idea where to start; the irrlicht source code is as weird as the engine is easy lol

The first link I posted shows how to create something similar yourself. The second link gives you a ready-made solution that is much more capable, but using it might be a bit difficult, depending on how well you know C++.
