scroll event for script panel mouse callback

@d-healey Huh, thanks. So I'd put a component into the viewport, and scroll it?

I still don't see how I could get access to mouse scroll values, which I'd use for other stuff than just scrolling a component.

[David Healey]

@aaronventure Ignore me, I completely misread the topic on my phone and thought this was about viewports specifically.

[Christoph Hart]

Yes that‘s a sensible request and I vaguely remember working on this at some point.

[Dan Korneff]

yay! This is perfect timing for a viewport that I'm recreating with panels.

[oskarsh]

@Christoph-Hart hey is there an update on this?

This is the missing piece to attach a broadcaster to a EQ Floating Tile and get the Q values changes via the scroll. Also this allows for some unique input methods zoom, knobs ...

Please consider taking a quick look at this.

@Christoph-Hart friendly bump while HISE is seeing a lot of good commits :)

Bump

I found this excellent snippet on the forum from Christoph (can't find the original post now) that allows you to control EQ bands on the draggable filter panel and have it update knobs on the UI.

However I noticed a bug which I think is related to this thread - when you update the Q value by hold shift + click and drag the frequency and gain bands update correctly, however if you adjust the Q using the scroll wheel they don't update.

Basically the Band Selected doesn't fire when using the scroll wheel over a band.

I agree!

[bendurso]

@oskarsh Another friendly bump.

I want to use it to move panels down/up.

[whoopsydoodle]

Old thread, I know... but wondering is there a way to do this in 2025?

I'm using a panel to draw EQ controls. I have control over freq with click and using a right click modifier I can do Q. Is there a way to capture the mouse scroll wheel so I can map that to control Q value with a panel instead of needing right click? Pretty much every other modern EQ plugin uses scroll wheel for Q adjustment so I very much would like to do that.

I'm using custom DSP so afaik I can't map that to a default filter floating tile, instead I'm drawing everything I need on a panel.

If it's going through scriptnode I think you can.

And the answer to your question is nope.

[whoopsydoodle]

@d-healey So you think I can use the filter floating panel but can't capture mousewheel from a panel?

[David Healey]

@whoopsydoodle Yes

[aaronventure]

@whoopsydoodle Currently the only way to use a scroll wheel in a custom control is to use a WebView. Use it for your EQ panel.

Would it be possible to add

event.scroll
and
event.scrollValue

to the Script Panels MouseCallback?

@Christoph-Hart apologies since it looks like it's T-Shirt season for me--do you think this is a feature you can look at integrating? I am trying to add a Zoom/Scrolling feature to my panels and this is just what I need...

[HISEnberg]

@HISEnberg Friendly bump on this !!
