Queued Custom Type Example | Qt Core 5.12.3 This example showed how a custom type can be registered with the meta-object system so that it can be used with signal-slot connections between threads. For ordinary communication involving direct signals and slots, it is enough to simply declare the type in the way described in the Custom Type Example. Communicating with the Main Thread - InformIT The Image Pro application shows how Qt's signals and slots mechanism makes it easy to communicate with the main thread from a secondary thread. Implementing the secondary thread is trickier, because we must protect our member variables using a mutex, and we must put the thread to sleep and wake it up appropriately using a wait condition. QThread with signals and slots | Qt Forum The recommended way of working with threads in Qt has changed since the documentation was written. It is usually better not to add signals, let alone slots, to QThread. Instead, create a QObject (derived) instance, and call moveToThread on it to move it to the thread. Put your signals and slots in this worker object instead.
