灵活键盘插入模式改写或插入

发布于 2024-07-25 07:45:42 字数 111 浏览 5 评论 0原文

在我的 Flex 应用程序中，我想以编程方式了解插入键的编辑模式。在应用程序的状态栏中应该有一个指示符，指示当前工作的模式。由于插入键是切换键，我如何知道它的模式？

提前致谢。

您可以使用 KeyboardEvent.KEY_DOWN 和 KeyboardEvent.KEY_UP 记录按下的按键。您必须在申请完成后将它们添加到舞台上，否则它们将不起作用。

<mx:Application applicationComplete="ApplicationComplete()" etc...

然后有一个函数：

    public function ApplicationComplete():void {
    stage.addEventListener(KeyboardEvent.KEY_DOWN, KeyDown);
    stage.addEventListener(KeyboardEvent.KEY_UP, KeyUp);        
}

然后是事件函数：

    public function KeyDown(e:KeyboardEvent):void {
        if (e.keyCode = whateverTheInsertKeyCodeIs) {
                   isInsertPressed = true;
            }
}
public function KeyUp(e:KeyboardEvent):void {
    if (e.keyCode = whateverTheInsertKeyCodeIs) {
                   isInsertPressed = false;
            }
}

或者如果您将它用作切换：

    public function KeyDown(e:KeyboardEvent):void {
        if (e.keyCode = whateverTheInsertKeyCodeIs) {
                   insertToggle = !insertToggle;
            }
}

我希望这会有所帮助！

You can record the keys being pressed with a KeyboardEvent.KEY_DOWN and KeyboardEvent.KEY_UP. You have to add these to the stage on application complete or they will not work.

<mx:Application applicationComplete="ApplicationComplete()" etc...

And then have a function:

    public function ApplicationComplete():void {
    stage.addEventListener(KeyboardEvent.KEY_DOWN, KeyDown);
    stage.addEventListener(KeyboardEvent.KEY_UP, KeyUp);        
}

And then the event functions:

    public function KeyDown(e:KeyboardEvent):void {
        if (e.keyCode = whateverTheInsertKeyCodeIs) {
                   isInsertPressed = true;
            }
}
public function KeyUp(e:KeyboardEvent):void {
    if (e.keyCode = whateverTheInsertKeyCodeIs) {
                   isInsertPressed = false;
            }
}

Or if you're using it as a toggle:

    public function KeyDown(e:KeyboardEvent):void {
        if (e.keyCode = whateverTheInsertKeyCodeIs) {
                   insertToggle = !insertToggle;
            }
}

I hope this helps!
