Titolo: Gestire un thread Watch/notifier in esecuzione in una libreria esterna

"Gambas is very capable of interfacing with external libraries, as
documented in:
http://gambasdoc.org/help/howto/extern?v3

I got it all working fine, i can call a function inside the library and i
get a value back (if there is a return value in the function).

Only I want something else now ... Within the library there is a
watch/notifier thread running which captures data from the serialport. This
data comes in independantly from the calls done to the library.

Is it possible to define a hook in Gambas (or the library) that the library
can initiate calls and push information to the main Gambas application?
Thus without having to call a certain function to poll the data, i want to
have it pushed from the library.

Regards,
Alex"


" You can use any gambas function as callback *provided that the callback
is called in the main thread and not in another thread*.
