For any C++ developer who's used Qt, we've grown to love the Signals/Slots idiom it presents for creating clean Observer code. However, it relied on the Qt Moc pre-compiler tool, which meant any project that wanted to use this feature had to use follow along with the Qt idiom, which really made Qt applications look potentially foreign despite being written in C++. Threads Events QObjects - Qt Wiki Qt basics: QObjects, signals and slots, event handling; what a thread is and what the relationships are between threads, processes and the operating system; how to start and stop a thread, and wait for it to finish, under (at least) one major operating system; how to use mutexes, semaphores and wait conditions to create thread-safe/reentrant ...

Otherwise, the behavior is the same as the Queued Connection." Can Qt signals can be safely emitted from another QThread It's safe to emit signals from other threads, if you use auto or queued connections.Auto is deduced to be queued in situations where the signal is emitted in a thread in which the receiving QObject do not have affinity. Direct connections are not thread safe.. There is a "Signals and Slots Across Threads" section in the documentation that deals with emitting signals to objects in different ...
