FLASH14: Using redundant keyboard and mouse event handlers in Flash

Example Code:

import fl.accessibility.ButtonAccImpl;
import fl.controls.Button;
import flash.accessibility. *
import flash.events.FocusEvent;
import flash.events.MouseEvent;
import flash.net.navigateToURL;
import flash.net.URLRequest;

ButtonAccImpl.enableAccessibility();
var states: Object = {
  "Alabama": "Alabama is a state located in the southeastern region of the \
    United States of America.",
  "California": "California is the most populous state in the United States",
  "New York": "New York is a state in the Mid-Atlantic and Northeastern \
    regions of the United States"
};

var buttons: Array =[];
var button: Button;
var accProps: AccessibilityProperties;
var count = 0;
for (var i in states) {
  button = new Button();
  button.label = i;
  button.addEventListener(MouseEvent.CLICK, clickHandler);
  button.addEventListener(MouseEvent.MOUSE_OVER, highlightHandler);
  button.addEventListener(MouseEvent.MOUSE_OUT, unHighlightHandler);
  button.addEventListener(FocusEvent.FOCUS_IN, highlightHandler);
  button.addEventListener(FocusEvent.FOCUS_OUT, unHighlightHandler);
  accProps = new AccessibilityProperties();
  accProps.description = states[i];
  button.accessibilityProperties = accProps;
  addChild(button);
  button.x = 30
  button.y = 30 + count * 30;
  buttons[i] = button;
  count++;
}

function highlightHandler(e) {
  descText.text = states[e.target.label];
}

function unHighlightHandler(e) {
  descText.text = "";
}


function clickHandler(e) {
  var url: URLRequest = new URLRequest("http://www.wikipedia.org/wiki/" + e.target.label);
  navigateToURL(url, "_self");
}
