Multithreading Technologies in Qt | Qt 5.12 Move the worker to the new thread. Send commands or data to the worker object over queued signal-slot connections. Permanent: Repeatedly perform an expensive operation in another thread, where the thread does not need to receive any signals or events. Write the infinite loop directly within a reimplementation of QThread::run(). Start the thread ... Chapter 28. Boost.Signals2 - 1.55.0 This documentation describes a thread-safe variant of the original Boost.Signals library. There have been some changes to the interface to support thread-safety, mostly with respect to automatic connection management. This implementation was written by Frank Mori Hess. Chapter 30. Boost.Signals2 - 1.61.0 This documentation describes a thread-safe variant of the original Boost.Signals library. There have been some changes to the interface to support thread-safety, mostly with respect to automatic connection management. This implementation was written by Frank Mori Hess.

Thread-Safety - 1.67.0 - boost.org It is expected that slot objects will be created then connected to a signal in a single thread. Once they have been copied into a signal's slot list, they are protected by the mutex associated with each signal-slot connection. The signals2::trackable class does NOT provide thread-safe automatic connection management. In particular, it leaves

Signaling Another Process (The GNU C Library) A process can send a signal to itself with a call like kill (getpid(), signum). If kill is used by a process to send a signal to itself, and the signal is not blocked, then kill delivers at least one signal (which might be some other pending unblocked signal instead of the signal signum) to that process before it returns. Signals, threads and the use of SIGUSR1 - C / C++ When I press CTRL-C for instance, the thread catches the signal and stops all the other threads. But, when no event is generated, the risk is that the thread would be waiting for ever; that's why, when the application normally finish without an asynchronous signal, I send a 'SIGUSR1' to the thread above and the application normally ends. Event/delegate (signal/slot) mechanism implementation for C++ ... From the other hand, Qt's implementation of signal-slot mechanism has its own limitations - it does not support slot parametrization and usage of signals and slots in interfaces. Implementation provided by Boost.Signals is unsatisfactory as well. This motivated me to make my own implementation. Features: * Thread-safe. Pthreads ProgrammingChapter 5 - Pthreads and UNIX
Nov 6, 2009 ... The solution for communicating from a secondary thread to the main thread is to use signal–slot connections across threads. Normally, the ...
c++ - Is it safe to emit signal from another thread ... Is it safe to emit a signal on an object from another thread (if the slot is connected as QueuedConnection)?I couldn't find a specific piece of documentation that would mention this, the most relevant quote I found is this:. QObject is reentrant. Threadsafe C++ signals done right : cpp - reddit.com Indeed. Qt signal/slot are specifically designed to make threads easy. You just write the code with signals and then, depending on the thread where the objects are created at the beginning (or to which thread they are moved), same signals act as direct calls or as message queues.
