Flex 3：如何模拟按下 Enter/Return 键

Question

标题几乎说明了一切...有没有一种简单的方法可以模拟按下 Enter/Return 键？

编辑：

我已经有了这么多，但我不确定如何让它在循环中运行：

var keyCode:uint = Keyboard.ENTER;
var e:KeyboardEvent = new KeyboardEvent(KeyboardEvent.KEY_DOWN, true, false, 0, keyCode);

我需要它在以下循环中运行：

for (var i:int = 0; i < changes.length; i++)
{
    if (changes[i][0] == "directorsPrep")
    {
        directorsPrep[changes[i][1]].phaseFillers[changes[i][2]].fillDisplayName.setFocus();
        // NEED IT TO RUN RIGHT HERE!
    }
}

Answer 1

for (var i:int = 0; i < changes.length; i++)
{
    if (changes[i][0] == "directorsPrep")
    {
        directorsPrep[changes[i][1]].phaseFillers[changes[i][2]].fillDisplayName.setFocus();
        // NEED IT TO RUN RIGHT HERE!
        // create the keyboard event; using your code
        var keyCode:uint = Keyboard.ENTER;
        var e:KeyboardEvent = new KeyboardEvent(KeyboardEvent.KEY_DOWN, true, false, 0, keyCode);
        // dispatch it    
        componentThatYouWantToDispatchKeyBoardEvent.dispatchEvent(e);
    }
}

componentThatYouWantToDispatchKeyBoardEvent 变量可以是扩展 EventDispatcher 或实现 IEventDispatcher。
