Signals and Slots

Well, bcake, liorean, jkd, anyone else. Whaddya think?

Seems pretty interesting -- and yet another New Thing™ to play with :p

It's not going to be high-performance, but I like it. D*mn Netscape and ECMA for not constructing these types of things to begin with!

Also, it's a little too large in code to be used casually - for it to be worth including, you must be in a project with huge amounts of code. A 100 line script wouldn't benefit from a possible reduction to 70 if you have to include far more code than you had initially to make the reduction.

I'm not sure I understand which problem the "signals and slots" approach tries to solve... is it an abstraction layer to enable a sort-of eventhandling for custom objects?

[liorean]

Pretty much, yeah.

In fact, I'm not that enlightened to really get the concept myself, even though I've used it in other languages. So, here's a few document on it:
<http://doc.trolltech.com/3.1/signalsandslots.html> (Ignore the QT specific details)
<http://www.joyinternet.net/cn/qt/html/signalsandslots.html> (also Qt)
<http://www.cs.tcd.ie/Martin.Emms/NLP/Notes/node118.html> (Guess what language?)

And, about just this one:

Thanks for the pointers, I'll have a look at them.

[liorean]

Alex Russell has cleaned the implementation up a bit, and written a nice documentation of it:

Just if anyone is interested.

Cool! Thanks liorean :thumbsup:

liorean, are you also a subscriber to the WDF-DOM mailing list? Just wondering... :D

And yeah, that is interesting stuff. Though the learning curve is definitely there, but it seems worth it for big applications.

Mordred, say which JavaScript related English speaking mailinglist I'm NOT a member of...

(I know there are ones. Especially the low-traffic ones. I'm doing my best to eliminate them too, though.)

If you read the archives you probably find a few messages by me in there. (I'm not very active in any of the mailinglists, though. Especially not since I rediscovered this place.)

I'm not that big a fan of PPK though - I find him a bit biased and not entirely objective. (His compatibility tables are still the best resource for that kind of information, though.)
