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.

After all, the signal-slot connection mechanism only specifies how to connect a signal to a slot - the signal's arguments are passed to the slot, but no ... But passing extra arguments can be quite useful. c++ - stack object Qt signal and parameter as reference ... Passing a reference to a Qt signal is not dangerous thanks to the way signal/slot connections work: If the connection is direct, connected slots are directly called directly, e.g. when emit MySignal(my_string) returns all directly connected slots have been executed. If the the connection is queued, Qt creates a copy of the referencees. So when ... c++ - Qt signals and slots pass by reference - Stack Overflow no a signal call is purely 1 way as more than 1 slot may be connected to a signal (and vice versa) you can either make it a true function call where you can do pass by reference. or create a signal-slot connection in the opposite direction as a callback Signals & Slots | Qt 4.8 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.
