Qt-based graphics backend - idea.

[Driss Ghaddab]

I'd just like to add the following:

I studied Matlab documentation (available online) to analyse the 
requirements on the event queue and the callbacks (e.g. they can be 
interruptible, or discardable, they can be a function handle, a script 
name, or a string etc, a callback can also have a pre-call and post-call 
hooks defined by the module (used for example in the timer module).

The event queue was designed to handle multiple modules (threads) and 
takes care that it won't be over flooded, or that all modules will have 
their event equally handled.

Cheers,

Driss
