How Qt Signals and Slots Work - Woboq Qt is well known for its signals and slots mechanism. But how does it work? In this blog post, we will explore the internals of QObject and QMetaObject and discover how signals and slot work under the hood. In this blog article, I show portions of Qt5 code, sometimes edited for formatting and brevity. C++ Multithreading in Boost | QuantNet Community C++ Multithreading in Boost. ... and ensuring that the code is thread-safe.
