[flexcoders] Detect if any of the Items on a List are Selected - thought it would be easier.

[steveb805]

The only property I could find, from the Flex docs, that tells you whether your 
List control has anything selected is: isItemSelected().

And this takes a parameter that refers to a specific item.  So before my Delete 
button handler, I check if any item is selected with the following:

private function deleteHandler() {

var bDoesNotHasFocus: Boolean = true;
var len:Number = projectList.dataProvider.length;

for (var i:int = 0; i <= len - 1; i++) {
  if (projectList.isItemSelected(projectList.dataProvider[i])) 
  {
    bDoesNotHasFocus = false;
  }
}
if (bDoesNotHasFocus)
  return;

  // the code to delete

}

Is there a better way, anyone?
Thanks,
Steve
