Thank Tom very much. In my country, few days ago is Lunar new year so
I don't work and reply :( 
Your solution is very good if the event handler in MXML file. I
correct my code follow you and have good result.
But I have only special case, the event handler in AS class

My code in main.mxml 



  ...
  


  

  


and code in systrayapp.as file

package com
{
  import flash.desktop.DockIcon;
  import flash.desktop.NativeApplication;
  import flash.desktop.SystemTrayIcon;
  import flash.display.Loader;
  
public class SysTrayApp extends Sprite
  {
  public function SysTrayApp():void{
NativeApplication.nativeApplication.autoExit = false;
var icon:Loader = new Loader();
var iconMenu:NativeMenu = new NativeMenu();
var showCommand:NativeMenuItem = iconMenu.addItem(new
NativeMenuItem("Show"));
showCommand.addEventListener(Event.SELECT,
function(event:Event):void {
   
NativeApplication.nativeApplication.activeWindow.stage.nativeWindow.visible
= true; 
});

}

So the error display when I click "show" menuitem in taskbar
TypeError: Error #1009: Cannot access a property or method of a null
object reference.

In debug mode the error at line
"NativeApplication.nativeApplication.activeWindow.stage.nativeWindow.visible
= true; "

how to solve it?
