C++ input question

I am attempting to build a small local-purpose 3d engine, which has to be platform-independent and right now I'm looking for a way to handle different possible types of user input.

This, obviously, includes mouse / keyboard events and possibly, another analogue controllers (joysticks, for example). I can think of several ways to implement this and am seeking for an advice - what would be better.

So far, I can write my own controller event handling and dispatching module, reimplement the whole functionality myself, though I guess I would face some troubles making this work for different platforms and integrating it. That's the hardest and the reinventing way.

Another approach would mean reusing some existing scheme / library for this sort of things, but I can't come with a good choice. Qt seems like an overkill for my small library, allegro and other SDL-like libraries have pretty tight logic coupling and writing a generic wrapper around them could become even harder then rewriting everything from scratch.

Maybe there is some app开发者_开发问答ropriate library, which could help me in this situation?

What would you do?

Thank you.

OIS is pretty good. It's the default one that the OGRE tutorials use.
