[Qt-interest] Force the emission of a signal

[Ian Thomson]

Hi,

You can connect a signal to a signal. It's documented here:
http://doc.trolltech.com/4.5/qobject.html#connect
It's true that this isn't made so obvious in the signal slot documentation.

The example code pasted by Thiago is able to hook in to a class which 
you don't have access to. It is interesting but it is a horrible hack. I 
would certainly recommend the private/friend idea if you want a safe way 
of doing what you ask.

Cheers,
Ian.
