ViewPort scrolling

[Lindon]

So I'm trying to geta viewport to scroll, along with the text I'm putting into its child widget(a text box)

I've tried:

LogViewport.set("viewPositionY",logPosition);

and

LogViewport.set("viewPositionY",0);

and

LogViewport.set("viewPositionY",1);

all of these fail to work for some reason - it just leave the viewport at the bottom...

what am I doing wrong?

@Lindon Got a snippet?

[Lindon]

My work is done

[Lindon]

@d-healey - sadly not. wont work in the real project --- I completely replaced the viewport and the label, still broken, not doing anything different...

[Lindon]

@Lindon now I'm getting very odd behaviours, the knob I'm using wont reset its value...

Sadly no this has exactly the same problems....

See how when you init the snippet it should set the knob to 0.5 - but it doesnt,..

Again its another of these controls that doesnt have a call back theat will execute - and should have, here:

the button should move the viewport down slightly each time - and it does right to the end , then you manually move the viewport back to the top - and it fails to work again...because the viewPositionY never gets reset...

-- this renders the viewport programatically useless..

[d.healey]

@Lindon The setting is uni-directional as Christoph put it - https://forum.hise.audio/topic/4863/script-viewport-position/3?_=1657893745416

[Lindon]

@d-healey I guess I should let him know I require this then....

@Christoph-Hart !!

[Christoph Hart]

@Lindon I've pushed some changes that write back the position into the property, but not sure if it works 100% for what you want.

[Lindon]

@Christoph-Hart ok great thanks - I will try it out.

[d.healey]

@Lindon The viewport callback doesn't get triggered when you scroll though, so not sure it will do what you need.

[Lindon]

@d-healey - yeah I might be able to live without that,,,

[civet]

Is it possible to initialize the scroll position of the viewport or save its position in preset?
