Below are some suggestions for troubleshooting signals and slots in the Qt C++ library. 1. Check for compiler warnings about non-existent signals and/or3.

This lets the target thread finish its current task before the slot starts running, while the original thread continues running in parallel. To place an invocation in an event loop, make a queued signal-slot connection. Whenever the signal is emitted, its arguments will be recorded by the event system.

A detailed discussion of thread handling in Qt. Qt provides thread support in the form of platform-independent threading classes, a thread-safe way of posting events, and signal-slot connections across threads. This makes it easy to develop portable multithreaded Qt applications and take advantage of multiprocessor machines.
c++ - Qt Signals and slot thread safety - Stack Overflow 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. If you omit connection type, it would be Qt::AutoConnection. In this case if you emit a signal from one thread, and catching it in another one (e.g. in main GUI thread) - Qt will put a slot's ...
