Fast C++ Delegate: Boost.Function 'drop-in' replacement ... Furthermore, FD.Delegate is a Boost.Function 'drop-in' replacement. So instead, we use the equal_to() member function for an equality comparison between two delegates. The following code snippet is a pseudo-code illustration of how comparison between two delegates is performed in order. // Exposition purpose only.

Signals and Slots. In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal. Signals & Slots | Qt Core 5.12.3 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. SignalsandSlots in C++ - sigslot - C++ Signal/Slot Library

There are two drawbacks in this simple implementation: It’s not threadsafe and you cannot disconnect a slot from a signal from within the slot callback. Both problems are easy to solve but would make this example more complex. Using this Signal class other patterns can be implemented easily. Why I dislike Qt signals/slots - elfery Why I dislike Qt signals/slots (Originally posted on Sunday, February 19th, 2012.) I've created over a dozen small projects using Qt by now.
