I'm trying to make a simple web app that displays a piano-roll
style grid that you can click in to activate or deactivate notes.
And I'm building it off of the MVC classes that I borrowed from
Michael Haufe. But I feel like I'm not really making use of the
Controller part.

What does the Controller really do in an MVC design? Should I
stuff all my button handlers (and their helper functions) in there?
In the current implementation, the Controller is just 4 functions
to access an associated Model and View.

class Controller {
getModel(){ return this._model; }
setModel( model ){ this._model = model; }
getView(){ return this._view; }
setView( view ){ this._view = view; }
}

Is there more stuff it could do? Or more stuff it ought to do according
to other interpretations of MVC?

I stumbled upon this concise answer.
https://stackoverflow.com/a/8497887/733077
which suggests that yes, the controller should encapsulate all the
"actions" and do manipulations on the model. The way I'm doing it
now, the model manipulates itself.

In my understanding,

Model is passive. It just ensure data store coherency. It handle
semantics of the application, invariants, ...

Views display Model in the UI. Views listen to Model to ensure
accuracy of display. Views also display widgets that let the user
interact (buttons, text fields).

Controllers listen Views for User interactions and translate its as
actions on the model. Theese interactions update the Model that notify
Views that update to display the new state.

Ok. Yeah, that makes sense. This sounds like a more "classical" MVC
division. So if I wanted to move towards this with my piano roll app,
then my Control Panel should be a View or maybe even each button.
Then the View gets event notifications, passing those to the Controller.
And the Controller should have all my app's "actions". In the piano roll
app all these actions are currently methods of the Model, so they
ought to be methods of the Controller, called when the controller gets
an event from View.

That does seem like a more "organized" organization than the way
I'm doing it now.

I threw together a quick MVC example this morning. Imperfect and a bit verbose but conceptually
you might find it useful:

My "betaness", you piece of shit?? Your code *is* fucking pathetic, but Dunning-Kruger remains a compliment: I *do* have posted so many code already, you retarded piece of lying shit, you and co., including a didactic example of MVC + knockout + timers + what-not, and *you* were not even able to understand what was what...!!

Very cool. Thanks. It seems that my problem is not applying MVC per se, but applying
Object Orientation more generally. But my big take-away is that the app itself *is* the
controller, or more perspicuously an instance of a subclass of a controller.

That both answers my question and sheds light on my X/Y problem to boot.
Nice one. Thanks again.

Your just so anal Julio i think the programmer paradigm have eaten you. You can do things not by the book and still get results.
This is a 50$ soundcanvas SC-7 one of Rolands first, played on an old Tascam FW1884 device.

A song played up with my vanilla javascript sequenser through the gear i mention above 200$ total, it ought to sound shit but it sounds lovely, because even i know my programming skills really not there i put my effort where it matter.
I would say the recording abilities match the playup, if not too aggresively hit with input data.

You asshole(s) have just got no clue what *programming* even means.

So let me give you a kick-start: there is no such thing as a "programming

An engineering discipline, to be specific.

1) You don't know what "Plonk" means - otherwise you would not even have
read the post which you replied to.

To "plonk" someone means to add the sender to a killfile to ignore all
future postings. Obviously you don't even know what a killfile is. You
just write "*Plonk*" but still read everything someone writes.

2) What exactly do you think to achiev with calling someing "piece of
shit", "piece of lyging shit", "another planetary fraud" etc.?

There is a programming paradigm, maybe just not in your world:

Have you ever noticed Julio its never the anal obsessed disciplined that come up with the good ideas, they are just caretakers of ideas, they love to drivel in documentation.
They are just the janitors of ideas LoL.

That said obviously both parties needed, to get anything done.

Another resident retarded cunt retorts with some links... but, can you even read English? As I have *repeatedly* pointed out around here, the whole arena has been hijacked and flooded with just FRAUDULENT BULLSHIT since the mid '90s.

But, even that aside, *you* cannot discern, but those articles you together with the whole bandwagon take for gospel, are utterly fucking WRONG on the WHOLE line!! Just you don't know shit and will only trust your authorities...

And, even aside that, you fucking retarded cunt: one thing is "coding paradigms" a la functional vs imperative, another is "*the* programming paradigm" a la Jonas and a la what a bunch of fucking retarded polluters of all ponds you are.

And even said that, what just a *sucker* in fact you are, by the way...
