No so clear haha. Has every kind of event "undefined" order? or only when
connecting to "javascript" signals? For example, if I connect two or more
slots to the "closeEditor" signal of an ItemDelegate, is that order also
undefined? Because the "closeEditor" signal doesn't depend directly on
javascript events, rather, its triggered "manually" by the ItemDelegate
class, and in that case, in my understanding, the order is the one defined
by the boost::signals2 library (which is the order of connections).
