New-style Signal and Slot Support¶ This section describes the new style of connecting signals and slots introduced in PyQt4 v4.5. One of the key features of Qt is its use of signals and slots to communicate between objects. Their use encourages the development of reusable components. A signal is emitted when something of potential interest ...

Signals and slots is a language construct introduced in Qt for communication between objects[1] which makes it easy to implement the observer pattern whileThis is similar to C/C++ function pointers, but signal/slot system ensures the type-correctness of callback arguments.[citation needed]. Signals & Slots | Qt Core 5.12 The signals and slots mechanism is type safe: The signature of a signal must match the signature of the receiving slot. (In fact a slot may have a shorter signature than the signal it receives because it can ignore extra arguments.) Since …

Signals and slots are loosely coupled: a class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type.
A few months ago I wrote about passing extra arguments to slots in PyQt.Here, I want to briefly discuss how the same effect can be achieved with Qt itself. C++ is not as dynamic as Python, so Python's approaches of using lambda or functools.partial won't work .Fortunately, the Qt folks provided a solution that can make passing extra arguments to slots relatively simple. Qt5 Tutorial Signals and Slots - 2018 - bogotobogo.com Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type. Qt.ConnectionType BlockingQueuedConnection public static final Qt.ConnectionType BlockingQueuedConnection Same as QueuedConnection , except that the current thread blocks until the slot has been delivered.This connection type should only be used for receivers in a different thread. Note that misuse of this type can lead to dead locks in your application. Differences between String-Based and Functor-Based - Qt
