Detailed Description
template<typename... As>
class Pt::SignalSlot< As >
SignalSlot is a "slot wrapper" for Signal objects. That is, it effectively converts a Signal object into a Slot object, so that it can be used as the target of another Signal. This allows chaining of Signals.
Member Function Documentation
◆ callable()
|
virtual |
The concrete slot returns its stored callable converted to Callback via a derived-to-base conversion. Callers downcast the result to Callable<R, As...> or Invokable<As...> to invoke it.
Implements Slot.
