The 7th part of my series on writing applications in C++ using Qt and boost:

Messaging and Signaling in C++

by Jens Weller

From the article:

This time it is about how to notify one part of our application that something has happened somewhere else. I will start with Qt, as it brings with signals and slots a mechanism to do exactly that. But, as I have the goal not to use Qt mainly in the UI Layer, I will also look on how to notify other parts of the application, when things are changing.
