alias GObject::SignalEmissionHook


A simple function pointer to get invoked when the signal is emitted.

Emission hooks allow you to tie a hook to the signal type, so that it will trap all emissions of that signal, from any object.

You may not attach these to signals created with the %G_SIGNAL_NO_HOOKS flag.
