The event management of gambas has nothing to do with qt event management, 
except that, in the qt component, gambas event are raised when qt events are 
raised.

To raise an event, you have the GB.Raise() function in the gambas API.

The interpreter event loop I didn't write yet is simply a call to select().

There is a function named GB.Watch() in the gambas API to ask the event loop 
(qt one, or the not yet written one) to watch a file descriptor, for reading 
and/or writing.

See CProcess.c in the interpreter source code for more details.
