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 can take any number of arguments of any type.
