Qt signals slots thread safety

Qt signal argument thread safety, c++,multithreading,qt,… It depends on the connection between SIGNAL and SLOT. If you are using the default one, which is Qt::AutoConnection, it acts like Qt::QueuedConnection for cross-thread connections. In Queued Connection, all signal parameters are copied to the queue and passed by value even though you... Qt Signals/Slots and Threads - dskims.com

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.

Qt signal slot with threads qt. I have a problem with signal/slots in a QThread class. My design looks like this: class Manager : public QObject { Q_OBJECT public: Manager(QObjectSignals sent to a QThread object will go to the thread of the parent object. In this case to the same thread that created it. To have a object live... Qt 5: emit signal from non-Qt thread (C++) - Codedump.io I faced an issue that signals, emitted from a non-Qt thread without Qt event loop, are not received by objects in QThread with the event loop. I have found that emitting from a non- Qt thread worked before with Qt::QueuedConnection connection type set explicitly, according to this and this questions.

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." Signals/slots accross threads | Qt Forum Qt::DirectConnection forces Qt to invoke the receiving slot/signal directly, and it doesn't care about threads, so it's not thread safe. Qt::QueuedConnection forces Qt to "delay" invocation of the receiving signal/slot by posting an event in the event queue of the thread the receiving object resides in. When the signal/slot is actually executed ... SLOT/SIGNAL safety with QByteArray &references | Qt Forum That's one of the reasons many of the "data" classes in Qt are implicitly shared, and what's more they have internal thread-safe reference counting. On a side note one of the side effects of using signals and slots is you shouldn't need to use mutexes directly. The signal slot connection (with a few rare exceptions) is safe across thread ...
