[solved] how do callback works?

[patricecolet]

Hello,

I'd like to store the state of widgets somewhere and recall it sometime

Couldn't find by whom mecanism it could be possible, except saving the state into a file

Can I change value of cc on a controler from another widget?

Hi, Here's an updated version in which the behavior of the fader can change for each parameter. variableFader5.json (30.9 KB) In short, there are three functional main components here: a fader five buttons for synth parameters five variables where the value of each of these parameter is stored Pressing a button sets the behavior of the fader for the corresponding parameter (range, # steps, linear or logarithmic behavior, color, name) Next the fader value (position) is set according to the…

maybe

Thanks for the light.

I see the idea, but I wouldn't like to create a variable for each parameter, imagine we have hundreds of parameters... That's why I'm using an object in value that is updated by a script triggered by a button. It would be nice if there would be a way to trigger a single script for all the buttons since it's exactly the same script.

Anyways, I couldn't find how to set a value without triggering the "onValue" script, that causes feedback loops, and wrong value assignements.

A solution would be about using VAR{} somewhere, but I couldn't figure it out.

I might dig again with a custom module using variable widget for storing the states.

set('id', value, {script: false})

would prevent the loop.

Thank you, I still not read documentation carefully enough.

AFAIU a callback would be a variable widget where value can contain arguments for the function residing into "onValue" property.

Hi,

is it what you want to achieve ?

Recall values of 4 buttons

hi @jean-emmanuel Thanks for your explanation. [setGetState] Here is an example of the two first solutions. setGetState.json (13.3 KB) Next step : use this concept with a matrix. which syntax to get the state of a button matrix. Edit : for a matrix state = get('matrix_1') // save_button var state = stateGet('matrix_1') setVar('load', 'my_var', state)

I don't understand, callbacks are a pure javascript thing (usually, a function to be called when a specific event occurs), in open stage control there are but a few things referred to as callbacks (ctrl+f "callback" in Scripting - Open Stage Control should cover most of them).

Hello,
this solution is quite simple and elegant, thank you for pointing this.

Yes, I'm already using things like setTimeout() but I didn't try runAs() yet.

That is what I'm trying to achieve, calling a single function when some event occurs from different widgets.

The answers I got from this thread should lead me to something neat.

In fact I'm building a 'custom widget' using svg and buttons for svg bindings (maybe there is something more elegant than using button widgets for mouse bindings?).
When I'm done, I should come in the forum with an example's proposal.

The canvas widget is an all-in-one solution for custom widgets.
