[Qt-interest] Normalized Signatures and Signaling....

[BRM]

Thanks.

Yes I am aware of signals->signals - I do it quite a bit.

My problem is that I have one signal generating data (from one thread) that needs to go do disparate sources (one pair type per thread pool), and I don't necessarily know all those pair types at compile time. (By "pair type" I am referring to basically something like QPair<value1,value2> or a similar structure that makes a key for the dynamic signal.)

So I basically need truly dynamic signals at run-time. If there's something built-in, great - but I haven't found anything other than an article in Qt Quarterly issue #16 (2005 #4) on the subject.

My choice is either having each slot filter the data (and thus pass around a lot of data in the signal/slot mechanism and event message queues between the threads), or to implement
a dynamic signal method, and then have data only going where it needs to go. The dynamic signals are, for me, a better option.

I believe the SIGNAL and SLOT macros add digits to the start.

Besides that, are you aware you can connect signals together? In fact 
you can connect QSignalMapper up to other signals.

Cheers,
