Flex：模拟按键 [英] Flex: Simulate key press

问题描述

我正在创建一个触摸屏Flex应用程序的虚拟键盘，我试图通过调度KeyboardEvent模拟按键。我已经写了一个处理函数来监听事件，并据此采取行动。到目前为止这么好...但它开始变得复杂，因为我必须管理焦点textInputs（简单），在这些字段中的光标位置（不那么容易），等
现在，如果只有一个实际派遣一个KeyboardEvent的方法，Flex将实际上解释为一个真正的按键所有这些问题将会消失...这是可能的吗？

解决方案 TextInput不使用KeyboardEvent / TextEvent进行文本输入，它使用与Flash Player / Keyboard进行交互的内部Flash TextField对象。

KeyboardEvent是用于启用发生键盘事件的通知。

要模拟键盘，您需要创建一个类，在接收到KeyboardEvent时将修改一个键盘的文本属性TextInput和相应的光标位置。

I'm creating a virtual keyboard for a touchscreen Flex app and i'm trying to simulate a key press by dispatching a KeyboardEvent. I've written a handler function to listen for the event and act accordingly. So far so good... but it's starting to get complicated as i have to manage the focused textInputs (easy), the cursor position in those fields (not to so easy), etc. Now, if only there was a way to actually dispatch a KeyboardEvent that Flex would actually interpret as a genuine key press all those issues would be gone... Is that possible?

解决方案

The TextInput does not use KeyboardEvent/TextEvent for text input, it uses internal Flash TextField objects that interact with the Flash Player / Keyboard.

The KeyboardEvent are used to enable notification of the Keyboard Event that occured.

To simulate a keyboard, you will need to create a class that upon recieving a KeyboardEvent will modify the text property of a TextInput and the cursor position accordingly.
