[Freekode-public] Events

[Diogo T. <fo...@gm...>]

Let's get the event handling discussion started.

-----

After some debate we ended up with two options on the table regarding the
event system implementation.

1) The first one is straightforward, it involves a global event queue. The
system and input events are
captured by a platform event handler and posted to the global queue using
kdPostEvent. In this case we
would have to do our own callback handling which would probably require
another container.

2) An alternative implementation is to use the event system and callback
handler provided by the operating
system. In Mac and Windows this implementation would be very straightforward
as both are thread safe and
support events and callbacks. However, this might not be true for all
platforms so the first implementation
might still be required as a fall back.

Unless we have more options, I think we have no choice but to implement the
first one. Once it's done,
supporting new platforms becomes almost trivial.
The second option, however, might still be useful by saving us some
resources and processing on some
platforms.

Fire away.
