Yes, you need it. The extern (C) function is what GDK invokes
on idle. In any GUI application there is a lot of idle time
waiting for events, what the addThreadIdle allows you to do is
take advantage of this and tell GTK that whenever it's sitting
around doing nothing, give this function a call.

Okay, thanks alot for your help. I think i will need some time
to understand this but one last question:
Do the errors come from the fact at i didn't use those GTK
thread mechanisms or that my function is not "spawnable"?
"std.concurrency.spawn(F, T...)(F fn, T args)
if(isSpawnable!(F,T))"
"Error: template std.concurrency.spawn cannot deduce function
from argument types!()(void delegate(Context cr, Widget
widget), Scoped Widget), candidates are:"
Keep in mind I know nothing about Cairo and I don't have time to
try your code, but what happens if you remove the Scoped template
from the Context parameter?
Also, have you checked if Cairo is thread-safe the way you are
using it in the spawned function? I'm not sure if Cairo has the
same restrictions that GTK widgets do.
