smartinvoke入门系列7——让Flex捕获键盘组合键
在FirstWin.mxml中通过调用addKeyBoardListener方法可以设置键盘监听器，该方法在cn.smartinvoke.gui.SIApplication类中定义，方法说明如下：
?
?public function addKeyBoardListener(listener:Function, target:Object, vk1:int = -1, vk2:int = -1, vk3:int = -1, characher:String = null):void
?
listener:Function????? 快捷键触发后的回调函数
?
???????? target:Object???????? 回调函数中this关键字所指代的对象
?
???????? vk1:int (default = -1)?? 第一个虚拟键
?
???????? vk2:int (default = -1)?? 第二个虚拟键
?
???????? vk3:int (default = -1)?? 第三个虚拟键
?
???????? characher:String (default = null)?? 字符键
?
如：在FirstWin.mxml中添加如下代码就可以实现键盘监听,
this. addKeyBoardListener(function():void{
Alert.show(“按下了ESC+E”);},this,VirtualKeys.VK_ESCAPE,-1,-1,"E");
?
this. addKeyBoardListener(function():void{
Alert.show(“按下了C”);},this,-1,-1,-1,"C");
?
?
this. addKeyBoardListener(function():void{
Alert.show(“按下了ESC+E”);},this,VirtualKeys.VK_ESCAPE,-1,-1,"E");
?
this.addKeyBoardListener(function ():void{
???????????????????????????????????? ?? Alert.show("你按下了 control + shift +K");
},this,VirtualKeys.VK_CONTROL,VirtualKeys.VK_SHIFT,-1,"K");
?
