Flex AIR 中的右键菜单

我很难在 AIR 应用程序中右键单击时出现上下文菜单或某种 NativeMenu。有人可以指出我正确的方向或提供一点示例代码以便我在脑海中澄清吗？

谢谢！

以下是示例：

package {
    import flash.ui.ContextMenu;
    import flash.ui.ContextMenuItem;
    import flash.ui.ContextMenuBuiltInItems;
    import flash.events.ContextMenuEvent;
    import flash.display.Sprite;
    import flash.display.Shape;
    import flash.text.TextField;

    public class ContextMenuExample extends Sprite {
        private var myContextMenu:ContextMenu;
        private var menuLabel:String = "Reverse Colors";
        private var textLabel:String = "Right Click";
        private var redRectangle:Sprite;
        private var label:TextField;
        private var size:uint = 100;
        private var black:uint = 0x000000;
        private var red:uint = 0xFF0000;

        public function ContextMenuExample() {
            myContextMenu = new ContextMenu();
            removeDefaultItems();
            addCustomMenuItems();
            myContextMenu.addEventListener(ContextMenuEvent.MENU_SELECT, menuSelectHandler);

            addChildren();
            redRectangle.contextMenu = myContextMenu;
        }

        private function addChildren():void {
            redRectangle = new Sprite();
            redRectangle.graphics.beginFill(red);
            redRectangle.graphics.drawRect(0, 0, size, size);
            addChild(redRectangle);
            redRectangle.x = size;
            redRectangle.y = size;
            label = createLabel();
            redRectangle.addChild(label);
        }

        private function removeDefaultItems():void {
            myContextMenu.hideBuiltInItems();
            var defaultItems:ContextMenuBuiltInItems = myContextMenu.builtInItems;
            defaultItems.print = true;
        }

        private function addCustomMenuItems():void {
            var item:ContextMenuItem = new ContextMenuItem(menuLabel);
            myContextMenu.customItems.push(item);
            item.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT, menuItemSelectHandler);
        }

        private function menuSelectHandler(event:ContextMenuEvent):void {
            trace("menuSelectHandler: " + event);
        }

        private function menuItemSelectHandler(event:ContextMenuEvent):void {
            trace("menuItemSelectHandler: " + event);
            var textColor:uint = (label.textColor == black) ? red : black;
            var bgColor:uint = (label.textColor == black) ? black : red;
            redRectangle.graphics.clear();
            redRectangle.graphics.beginFill(bgColor);
            redRectangle.graphics.drawRect(0, 0, size, size);
            label.textColor = textColor;
        }

        private function createLabel():TextField {
            var txtField:TextField = new TextField();
            txtField.text = textLabel;
            return txtField;
        }
    }
}
