Adobe AIR右键菜单和系统托盘（Tray)功能以及实现方法

右键菜单：

var mainMenu:NativeMenu = new NativeMenu();
var minimizeMenu:NativeMenuItem = new NativeMenuItem("Minimize");
var maximizeMenu:NativeMenuItem = new NativeMenuItem("Maximize");
var sepMenu:NativeMenuItem = new NativeMenuItem("",true);
var restoreMenu:NativeMenuItem = new NativeMenuItem("Restore");
var closeMenu:NativeMenuItem = new NativeMenuItem("Close");
minimizeMenu.addEventListener(Event.Select, handleMenuClick);
maximizeMenu.addEventListener(Event.Select, handleMenuClick);
restoreMenu.addEventListener(Event.Select, handleMenuClick);
closeMenu.addEventListener(Event.Select, handleMenuClick);
mainMenu.addItem(minimizeMenu);
mainMenu.addItem(maximizeMenu);
mainMenu.addItem(sepMenu);
mainMenu.addItem(restoreMenu);
mainMenu.addItem(closeMenu);
this.contextMenu=mainMenu;

系统托盘:

var sysTray:SystemTrayIcon =
   NativeApplication.nativeApplication.icon as SystemTrayIcon;
   sysTray.tooltip = "测试tray";
   //
   sysTray.menu = this.contextMenu;
   sysTray.addEventListener(MouseEvent.CLICK,trayClick);

 

如何将应用程序最小化到托盘,然后给托盘图标加右键菜单以及添加相应的事件,来激活应用程序窗体.

整个流程:

1.       初始化应用时改变系统默认情况下以系统X事件的处理.

2.       定义新处理逻辑(本文是弹出对话框)

3.       生成托盘图标并置于状态栏

4.       给托盘图标加上右键菜单(本文是exit,和open两项)

5.       给菜单加上相应的事件

6.       大功告成

 

主要方法:

 

private var dockImage:BitmapData;  

              

        //初始化Application里调用此方法,完成上面的第一步:  

            public function initApplication():void{  

                var loader:Loader=new Loader();  

                loader.contentLoaderInfo.addEventListener(Event.COMPLETE,prepareForSystray);//这里就是完成第一步的任务须,这个prepareForSystray就是对托盘的生在和菜单的控制  

                loader.load(new URLRequest("assets/images/32.png"));//这里先要加载托盘图标的小图片  

                this.addEventListener(Event.CLOSING,closingApplication);//设置关闭体的事件  

            }  

              

        //关闭窗体的事件  

            public function closingApplication(event:Event):void{  

                event.preventDefault();//阻止默认的事件  

                Alert.yesLabel="Close";  

                Alert.noLabel="Mini";  

                Alert.show("Close or Minimize?", "Close?", 3, this, alertCloseHandler);//弹出自定义的选择框, 关于Alert的详细用法,参考官方文档或我前面的相关文章.  

            }  

        //根据用户的选择来判断做什么,这里选择是就是关闭,选择否(Mini)就是最小化到托盘.  

        private function alertCloseHandler(event:CloseEvent):void{  

            if(event.detail==Alert.YES){  

                closeApp(event);  

            }else{  

                dock();//最小化到托盘  

            }  

        }  

          

    //生成托盘  

        public function prepareForSystray(event:Event):void{  

            dockImage=event.target.content.bitmapData;  

            if(NativeApplication.supportsSystemTrayIcon){  

                setSystemTrayProperties();//设置托盘菜单的事件  

                SystemTrayIcon(NativeApplication.nativeApplication.icon).menu=createSystrayRootMenu();//生成托盘菜单  

            }     

        }  

          

        public function createSystrayRootMenu():NativeMenu{  

            var menu:NativeMenu = new NativeMenu();  

            var openNativeMenuItem:NativeMenuItem = new NativeMenuItem("Open");//生成OPEN菜单项  

            var exitNativeMenuItem:NativeMenuItem = new NativeMenuItem("Exit");//同理  

            openNativeMenuItem.addEventListener(Event.SELECT, undock);  

            exitNativeMenuItem.addEventListener(Event.SELECT, closeApp);//添加EXIT菜单项事件  

            menu.addItem(openNativeMenuItem);  

            menu.addItem(new NativeMenuItem("",true));//separator   

            menu.addItem(exitNativeMenuItem);//将菜单项加入菜单  

 

            return menu;  

 

        }  

        //设置托盘图标的事件  

        private function setSystemTrayProperties():void{  

            SystemTrayIcon(NativeApplication.nativeApplication .icon).tooltip = "TurboSquid squidword";  

            SystemTrayIcon(NativeApplication.nativeApplication .icon).addEventListener(MouseEvent.CLICK, undock);  

            stage.nativeWindow.addEventListener(NativeWindowDisplayStateEvent.DISPLAY_STATE_CHANGING, nwMinimized);   

        }  

          

//最小化窗体  

        private function nwMinimized(displayStateEvent:NativeWindowDisplayStateEvent):void {  

            if(displayStateEvent.afterDisplayState == NativeWindowDisplayState.MINIMIZED) {  

                displayStateEvent.preventDefault();//阻止系统默认的关闭窗体事件  

                dock();//将程序放入托盘  

            }  

        }  

 

        //将本地应用程序放到托盘  

        public function dock():void {  

            stage.nativeWindow.visible = false; //设置本地程序窗体不可见  

            NativeApplication.nativeApplication.icon.bitmaps = [dockImage];//设置托盘的图标  

        }  

          

        //激活程序窗体  

        public function undock(evt:Event):void {  

        stage.nativeWindow.visible = true;//设置本地程序窗体可见  

        stage.nativeWindow.orderToFront();//设置本地程序窗体到最前端  

        NativeApplication.nativeApplication .icon.bitmaps = [];将托盘图标清空  

        }  

          

        //关闭程序窗体  

        private function closeApp(evt:Event):void {  

            stage.nativeWindow.close();  

        }
