Scrollable Panel: Detect when scroll starts or ends

[felixlaguna]

Hello! I have been looking at the docs and have not found a way to detect when the scroll starts or ends. The only event described in the docs is 'scroll', and when I attach to any of the BaseSizer events (like the onClick method), the scroll doesn't seem to work.

Maybe there is a way I am not seeing, or a workaround that could be in the docs.

How to define scroll start?

• On pointer down , or
• Pointer down then drag start?

[felixlaguna]

I could work with either of them actually. My real problem is scroll end, but help on the scroll start would be really welcome.

Scroll end would be pointer-up from scrollable panel. Is it correct? Scrollable panel will continue scrolling for a while after pointer-up.

Update:

Add 'dragstart', 'dragend' events to scroller.

scrollablePanel.getElement('scroller')
    .on('dragstart', function () {
        console.log('scroller.dragstart')
    })
    .on('dragend', function () {
        console.log('scroller.dragend')
    })
