[Qt-interest] concurrent-run of a static function

[Gabriele Kahlout]

Sorry, for trouble caused by the signature. I said I didn't write it with
mailing lists in mind. However i'll not lengthen it to include a 'mailing
list' note too. Applying it in a mailing list would mean that someone with
qt-interest at trolltech.com replies (In(senderAddress(x), MySafeSenderList)),
which is impossible ( --> _|_ ).

However, I fell back to my tendency to email back, a follow up in 48h. Sorry
=)
Also note the 'might' (⇒ ¬) in it, indicating the case where I don't resend.
However I may still not resend (not <-->), as I'll try to exercise here.


Back to the question:

I was referring to:

 // call 'void QImage::invertPixels(InvertMode mode)' in a separate thread
 QImage image = ...;
 QFuture<void> future = QtConcurrent::run(image,
&QImage::invertPixels, QImage::InvertRgba);
 ...
 future.waitForFinished();
 // At this point, the pixels in 'image' have been inverted


I tried several modifications to use a static function in palce of the
invertPixels, but failed. Since the doc doesn't explicit that one cannot use
static functions, I wondered. BTW the class is a singleton, so I may not use
an instance to call the static method.

Related to your concurrency claim (in 2 sockets x thread thread), what I
want to do should be equivalent, to having the function as a slot (and no
more singleton) and connect a signal to it. Isn't it?

P.S. Unless a notification (LON), please reply either with an answer OR with
" ACK" appended to this subject within 48 hours. Otherwise, I might resend.
In(LON, this) ∨ In(48h, TimeNow) ∨ ∃x. In(x, MyInbox) ∧ IsAnswerTo(x, this)
∨ (In(subject(this), subject(x)) ∧ In(ACK, subject(x)) ∧
¬IsAnswerTo(x,this)) ⇒ ¬IResend(this).

Also note that correspondence may be received only from specified a priori
senders, or if the subject of this email ends with a code, eg. -LICHT01X,
then also from senders whose reply contains it.
∀x. In(x, MyInbox) ⇒ In(senderAddress(x), MySafeSenderList) ∨ (∃y. In(y,
subject(this) ) ∧ In(y,x) ∧ isCodeLike(y, -LICHT01X) ).
