[AS3] List Component question

[absolutezero3424]

How do you check for a List item MOUSE_OVER/ROLL_OVER event on a List Component in AS3? Is there a way? I would think so....The same could be true for a TileList Component & a DataGrid Component.

[panel]

import fl.events.ListEvent;

myList.addEventListener(ListEvent.ITEM_ROLL_OVER, onItemRollOver);

function onItemRollOver(evt:ListEvent)
{
trace("Over")
}


Yes it will work for TileList Component & DataGrid
