Syntax for Setting and Getting Array Data From a Panel

@ulrik Isn't accessing an object property slower?

ulrik

@aaronventure I've never thought about that, maybe you're right.

aaronventure

@Christoph-Hart how to set an array, then? How to specify which element I'm setting? setValue only expects one parameter.

Christoph Hart

@aaronventure that parameter can be an array or an object (the only illegal type is string because that can cause weird number conversion issues).

ulrik

@Christoph-Hart @aaronventure Would this be a better implementation?
I store the min, max and range properties at init (so no more looking at properties at runtime)

@Christoph-Hart Alright, so what does it look like?

I feel like I'm miscommunicating this -- I can't figure out how to write these two lines of code.

What's the syntax for storing an array in a panel with .setValue(), and for getting it?

aaronventure

@ulrik Sure? I mean, the other one also only gets executed once perhaps, at the very first run while it's undefined.

This is what I was referring to:

I have a panel that I want to use to create a horizontal range slider.

Why not use the built in range slider?

Is it not broken?

setValue([0.5, 0.8]);
min = getValue()[0]; // case that panel is not initialised needs to be handled too though...

I never used it. But I just tried it and seems to be broken. I suggest we nag Christoph to fix it instead of hacking a panel (unless you need the panel method for some particular reason). :)

aaronventure

@d-healey The default controls don't let me define custom modifier behavior (ctrl, alt, shift), don't have the useful .data functionality and don't have the mouse callback.

Broadcaster would solve those issues I think (well not the data one).

aaronventure

@d-healey True, but I still can't disable built-in modifier behavior.

aaronventure

@Christoph-Hart Thanks.

Is there a way to set only one element, or do I have to be defining all elements every time I'm setting the value?

Is this done by setting these value somewhere else, like a local var which is an array

local tempVal = [];

and then passing the array itself every time I setValue

setValue(tempVal);

?

Christoph Hart

local v = this.getValue();
v[1] = "New Value";

// technically this is not required because the value is already == v
this.setValue(v); 

// this will fire the notification that the value has changed.
this.changed();

aaronventure

@Christoph-Hart

Got it working. Thanks.

Christoph Hart

@aaronventure FYI, I've added the ability to reassign modifier / mouse click types to different events.

Dan Korneff

@Christoph-Hart thanks! I was just about to request this :)

aaronventure

@Christoph-Hart Nice! A few questions:

1. This is just for re-assigning default modifiers, right? Or will mods.shiftDown return 1 if shift is down, therefore letting me do whatever?

2. Is the CTRL modifier the same for Windows and Mac, or is the Ctrl on windows firing the CMD modifier?

3. Given how we're creating an object here and there's no .data for a slider, what's the best way to approach encapsulation? I can set everything up within a single function, sure, but if the in-function reference is a local variable, I can't access it from e.g. the control callback in case I have one control that needs to do something else other than what I set up.

In my case, I'm using the panel, and have a sizeable function that handles everything: I have a few timers for various types and parts of an animation that happens on user action, and these timers are stored into widget.data.someTimer, so I can access them from anywhere. Moving to a slider would require figuring out how to keep the same functionality of the timers, while keeping the workflow the same (set up one type of control with a single function, passing relevant parameters).
