    Default Answered: List scroller, max position event

    hi,

    I am beginner in sencha touch, so i need help.
    i have a panel with a list. how can know that the scroller of this list is arrived to the bottom?

    I want to add an event listener to my panel when the list scroller has reached its maximum position.

    How can i do this?

    Help please.

  2. The Ext.scroller.Scroller has a scrollend event that will fire when the scrolling has stopped. You can then check against the maxPosition value.

    To get the Scroller instance:

    Code:
    var scroller = list.getScrollable().getScroller();
    To handle scroll to the max position:

    Code:
    scroller.on('scrollend', function(scroller, x, y) {
        if (y >= scroller.maxPosition.y) {
            //you have scrolled to the end of the list
        }
    }, list);
