Message-ID: <004a01c19df4$422470b0$9600a8c0@warp> (raw)
Hello, i'm trying to have my class having some event callback like this :
class wmenuitem (fcallback:wmenuitem->unit) =
object(self)
val func = fcallback
method activate = (func self)
end
but I'm having :
This expression has type < activate : 'a; .. > but is here used with type
wmenuitem = < .. >
Self type cannot escape its class
Is it really true that self cannot be a parameter ?
Any help ?
Thanks
Warp
