var mainMenu:NativeMenu = new NativeMenu();
var minimizeMenu:NativeMenuItem = new NativeMenuItem("Minimize");
var maximizeMenu:NativeMenuItem = new NativeMenuItem("Maximize");

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();
-
}
