如何在Flex/AIR中警告用户启用CAPSLOCK？-HowtowarnuserofCAPSLOCKenabledinFlex/AIR?

flash.ui.Keyboard.capsLock is not bindable so that code won't really work.

flash.ui.Keyboard.capsLock不可绑定,因此代码不会真正起作用。

I would invoke a function in the "keyDown" event for the TextInput and then check flash.ui.Keyboard.capsLock in that function. You can then set visible/includeInLayout on that Text, pop up an Alert, etc...

我将在TextInput的“keyDown”事件中调用一个函数,然后检查该函数中的flash.ui.Keyboard.capsLock。然后,您可以在该文本上设置visible / includeInLayout,弹出警报等...

try this

private function addHandler():void{
        //Called from app's creation complete event.
        //Listener to handle any keyboard KEY_DOWN event:
        this.addEventListener(KeyboardEvent.KEY_DOWN,handleKeyDown);
    }


private function handleKeyDown(event:KeyboardEvent):void{
     if (Keyboard.capsLock){
          lblCaps.visible =true;
     } else {
          lblCaps.visible =false;   
     }
}

call addHandler on creation complete

在创建完成时调用addHandler

In actionScript:

if(flash.ui.Keyboard.capsLock){
    // caps lock is on...
}

or MXML:
