Thank you. If I get you right, this will block events until I finish drawing,
but that is the purpose.
And is it possible to do it multi-threaded? In a way that input thread is
different than drawing thread?
Well, the glib mainloop always needs to be on the thread where glib is
initialized.
My favorite is #4.

I'm asking this because logically it is possible to process a game Loop with
glib main loop.
Does this solution involves running the game loop different thread of the
main loop?
I do it by manually iterating the glib mainloop within my gameloop.
I'm glad it's possible. Can you please explain how do you integrate this?
I'm new(half year) for the glib concepts, so the only integration I know with
Glib main loop is Idle.add ()...
Does you do this single threaded, or dual?
Just using the main thread, with MainContext.iteration()
IMHO there isn't a significant difference.

While this is indeed correct workaround, the Hildon binding should
probably be updated (so you get type-checking from the compiler).
In that case, can that be a different vapi so that we can still use
hildon-1 with diablo (maemo 4.x)?
Or at least keep the legacy version as hildon-1-diablo.vapi

Wow, that's a great writeup!
Did you have --Xcc=-I/usr/include/SDL as part of your compile line?
Just out of curiosity... Why is that necessary?
It's because SDL, unlike a lot of libraries bound for Vala, doesn't
have a pkg-config file defining include paths and the like.

It almost sounds to me like you want a C# compiler that targets real

What is the current state of interaction between Vala and Mono? I mean,
would it be possible to take a useful Mono library, rewrite it in Vala,
and make the Mono programs pretty much transparently use the rewrite
instead of the original library?
