How do I find the scroller for a specific component?

[drb]

I have components on a Panel which has scroller.

Sometimes the components are inside a FieldSet.

Is there a simple way to find the scroller or do I have to crawl my way up the parents until I find something with a Scroller?

Thanks

Do you create this Scroller (Ext.scroll.Scroller) manually or are you using the scrollable config for the Panel?

I'm using scrollable in the Panel config. The difficulty is that all I have to start with is the component.

I ended up writing a routine to crawl up the parents which seems to work:

        scrollIntoView: function (ctl) {
            var parent = ctl;
            var scrollable = null;
            // Find the scroller (if any).
            while (true) {
                if (!parent.hasParent()) {
                    return;
                }
                parent = parent.parent;
                if (!parent.isContainer) {
                    continue;
                }
                scrollable = parent.getScrollable();
                // If the parent is a container and it is scrollable, we found it!
                if (scrollable) {
                    break;
                }
            }
            var scroller = scrollable.getScroller();
            ...
        }

You should be able to use the .up('...') or .down('...') when you reference the component which basically runs up or down the list of components in use. I think you can search for the scroller that way. Read up on those functions from the docs. I would link it but it is taking too long to access them from my iPad right now.
