> > Code shops usually have their staff writing stock classes between assignments, and having signals&slots would make these classes handier to use. And large programming projects would benefit from looser coupling between objects. digitalmars.D - Signals and Slots in D - signals and slots are not as tightly coupled to a specific class as in your example.

How to Expose a Qt C++ Class with Signals and Slots to QML Use a Property, Signal or Slot? As we’ve already seen in the previous examples, properties, signals and slots offer different types of communication between C++ and QML: Slots allow communication from QML to C++: Slots are used to trigger C++ code from QML. You can use parameters and return values to pass data to and from C++.
Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal.
