Override ScrollList scrolling

Is it possible to override a ScrollList so that list scrolling is controlled by a separate widget? This separate widget is on the same screen as the ScrollList, but is outside of the ScrollList. I would still like to be able to use normal press & release on the Items inside the ScrollList.

In other words, I do not want to allow the user to scroll the ScrollList by dragging on the ScrollList itself.

If that is possible, exactly what would need to be overridden to accomplish that?

Hi @JonB​ !

The class ScrollBase has a virtual method animateToItem(int16_t itemIndex, int16_t animationSteps) that you could call on your ScrollList to animate to a specific item in your list.

Hope that helps!

Best regards,

Martin

Hi @Martin KJELDSEN​ !

Do you have a corresponding method (animateToItem) for scrollable containers?

Kind regards

It doesn't seem to be the case - It's different for scrollable container because you do not have list elements in the same way. You could probably adapt the code from ScrollList and do it yourself :)
