An event posted using a QueuedConnection is a QMetaCallEvent. When processed, that event will call the slot the same way we call them for direct connections. All the information (slot to call, parameter values, ...) are stored inside the event. Copying the parameters. The argv coming from the signal is an array of pointers to the arguments. The ...

Signals and slots is a language construct introduced in Qt for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code.The concept is that GUI widgets can send signals containing event information which can be received by other widgets / controls using special functions known as slots. This is similar to C/C++ function pointers, but ...

Chapter 67. Boost.Signals2 - Connections The corresponding slot was created and associated with the signal automatically. In Example 67.14, however, the smart pointer is associated with the slot by calling track(). Because the type of the slot depends on the signal, boost::signals2::signal provides a type slot_type to access the required type.
