戈壁滩上的狗尾巴花

某Tree上的menu
_menu = new NativeMenu();
_menuAddTopOU = new NativeMenuItem("Add Top OU");
_menuAdd = new NativeMenuItem("Selcet one OU ls");
_menu.addItem(_menuAddTopOU);
_menu.addItem(_menuAdd);
_menu.addEventListener(ContextMenuEvent.MENU_SELECT, onMenuSelected);
_menu.addEventListener(Event.SELECT, onMenuItemSelected);
_treeOUs.contextMenu = _menu;

监听函数:

// Menu打开后动态改变菜单内容
private function onMenuSelected(event:ContextMenuEvent):void {
var currentOU:OrgUnit = _treeOUs.selectedItem as OrgUnit;
_menuAdd.enabled = _actionAdd.enabled;
if(_menuAdd.enabled) {
_menuAdd.label = “Add OU in ” + currentOU.nameFullLocalized;
}else {
_menuAdd.label = “Select one UP first”;
}
}

// 选中Menu中某item后响应
private function onMenuItemSelected(event:Event):void {
if(event.target == _menuAddTopOU) {
trace(“右键点击增加顶级部门”);
onAction(_actionAddTopOU, null);
}else if(event.target == _menuAdd) [...]
