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();   

◦        }
