Thread safety in Qt p.27 A function is: Thread safe: if it's safe for it to be invoked at the same time, from multiple threads, on the same data, without synchronization Reentrant: if it's safe for it to be invoked at the same time, from multiple threads, on different data; otherwise it requires external synchronization c++ - Qt Signals and slot thread safety - Stack Overflow Let's say I have a signal change connected to a slot notify. If the change signal is emitted, the notify slot will start executing. Now what happens if a second change signal is emitted and the first notify slot didn't finish its execution? Is the second slot launched concurrently with the first? And if so, is Qt handling the thread-safety or ... Threads and QObjects | Qt 5.12 Signals and Slots Across Threads. Qt supports these signal-slot connection types: Auto Connection (default) If the signal is emitted in the thread which the receiving object has affinity then the behavior is the same as the Direct Connection. Otherwise, the behavior is the same as the Queued Connection."

The only way when slot will be launched concurrently is if you specified Qt::DirectConnection AND emitting signal in thread different from slot's thread.Is the second slot launched concurrently with the first? And if so, is Qt handling the thread-safety or it's up to the programmer to handle it? [QT] signals/slots между тредами не понимаю —… ... connect(&thread, SIGNAL(renderedImage(QImage,double))Смущает потому что(на сколько я ничего не понимаю)при передаче сигнала между тредами не известно когда сигнал попадет в слот. thread-safety - Qt соединяет два сигнала вместе, используя...… Qt сообщает, что можно соединить два сигнала вместе: Можно даже напрямую подключить сигнал к другому сигналу.

The first thing needed was additionally recording the signatures of signals/slots in exactly the same way Qt sees them. This way, we can theoretically do exactly the same matching Qt does.
