See UNISA – Summary of 2010 Posts for a list of related UNISA posts. Continued from UNISA Chatter – Design patterns in C++ Part 4: Widgets … getting started with the QT User Interface.
IMPORTANT POINT: It is important to emphasize that the intent of these posts are to share my learning’s as I dig through the last three subjects of my part-time UNISA studies. The posts by no means promote concepts or technologies … they are pure information sharing for fellow students … although the highlight that we explore more technologies and concepts that we typically prefer 🙂

QSemaphore is used to lock more that one resource and to ensure that threads only lock available resources.
Here is the simple example application I created … two threads creating hypothetical stock prices:
