Heres a quick answer from my undercafineated brain
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml";>
<mx:List id="myStateList" dataProvider="{statesList}"
multipleSelection="true" />
<mx:Button label="Remove States" click="dStates(event)"/>
<mx:Script>
<![CDATA[
var statesList:Array=new Array("AZ","CA","NV","MD","NY");
function dStates(event:Object):Void {
var lb = myStateList;
for ( var i = lb.length; i >=0 ; i--){
if(isInArray(lb.getItemAt(i),lb.selectedItems)){
myStateList.removeItemAt(i);
}
}
}
function isInArray(item:String,array:Array):Boolean{
for(var i=0;i<array.length;i++){
if(array[i] == item){
return true;
}
}
return false;
}
]]>
</mx:Script>
</mx:Application>
Essentially loop over all items in the list box, compare each to the
selectedItems. If a match, delete. The may well be a more elegant
solution, but I'd need coffee for that
