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.

If I’m about to modify a slot function I might take an extra minute to look around since most IDEs can’t tell syntactically where it’s used in a SLOT() macro. In this case you have to search for it textually.) Thanks to C++11 lambdas and Qt’s ongoing evolution, these short slots can be replaced by a more succinct syntax.

How to Use Signals and Slots - Qt Wiki
2002-3-31 · SignalsandSlots in C++ SarahThompson∗ March2002 1 Introduction This paper introduces the sigslot library, which implements a type-safe, thread-safe signal/slot mech-anism in C++. The library is implemented entirely in C++, and does not require source code … Copied or Not Copied: Arguments in Signal-Slot Connections? Therefore, we have one extra copy for every signal-slot combination. We must register the Copy class with Qt’s meta-object system with the command qRegisterMetaType("Copy"); in order to make the routing of QMetaObject::activate work. Any meta type is required to have a public default constructor, copy constructor and destructor.

QMetaType knows your types - Woboq
A Qt:: BlockingQueuedConnection is like a Qt:: QueuedConnection but the Signal-method will block until the Slot returns. If you use this connection type on QObjects that are in the same thread you will have a deadlock. And no one likes deadlocks (at least I don’t know anyone). Signals and slots - Wikipedia Another implementation of signals exists for ActionScript 3.0, inspired by C# events and signals/slots in Qt. Additionally, a delegate can be a local variable, much like a function pointer, while a slot in Qt must be a class member declared as such. How Qt Signals and Slots Work - Part 2 - Qt5 New Syntax It also knows the type of the signal arguments so it can do the proper type conversion. We use List_Left to only pass the same number as argument as the slot, which allows connecting a signal with many arguments to a slot with less arguments. QObject::connectImpl is the private internal function that will perform the connection. How Qt Signals and Slots Work - Part 3 - Queued and Inter ...
