I also had this initial idea:

Looks like an almost identical proposal was done some time ago:

Scoped-Listeners / Modernize listeners

I’ve made this little class, and it really revolutionised my programming style. Its a scoped listener, and very easily combines the listener (old-school) functionality with the ability to attach std::function lambdas to it (a more modern approach). It’s not a very sophisticated, its very plain and simple. Example: class TestComponent : public Component { public: TestComponent( ColourSelector* selector, MidiKeyboardComponent* keyboard ) { // attach updateUI to the ChangeBroadcaster of Col…

My thoughts about this: it would be really nice if it were possible, with some template magic, to do something like

ScopedListener <ChangeListener> listener (broadcaster);

ScopedListener <Button::Listener> listener (button);

etc.
