SignalActionProtocol

public protocol SignalActionProtocol : ShortcutActionProtocol

A GtkShortcutAction that emits a signal.

Signals that are used in this way are referred to as keybinding signals, and they are expected to be defined with the G_SIGNAL_ACTION flag.

The SignalActionProtocol protocol exposes the methods and properties of an underlying GtkSignalAction instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see SignalAction. Alternatively, use SignalActionRef as a lighweight, unowned reference if you already have an instance you just want to use.
