The example below shows how to add a tooltip on roll over event of flex ListBox items. I don’t say that this is the perfect way to do this…but i’m happy as long as it serves me…

just rollover any of the listbox items and it will show the index of that item. So once you’ve the index, i guess you can do any custom label operations.

Here is the source code for the above example:

tip = ToolTipManager.createToolTip(event.rowIndex+"",event.currentTarget.x+event.currentTarget.width,event.currentTarget.mouseY)as ToolTip;
}

ToolTipManager.destroyToolTip(tip)

itemRollOver="itemRollOver(event)" itemRollOut="itemRollOut(event)"/>

Here is the post which explains a much simpler way to create tooltips but you cannot custom place these tooltips:
