我在哪里可以找到与 Cocoa 的 NSEvent 类一起使用的关键代码列表? [英] Where can I find a list of key codes for use with Cocoa's NSEvent class?

问题描述

我正在寻找可与 Cocoa 的 NSEvent 类一起使用的可用键代码的完整列表.NSEvent 类有一个keyCode 属性，定义为unsigned short.以下代码在放置在适当的 UI 对象中时，将在按键代码被按下时回显:

I'm looking for a comprehensive list of the available key codes that can be used with Cocoa's NSEvent class. The NSEvent class has a keyCode property, which is defined as unsigned short. The following code, when placed in an appropriate UI object, will echo the key codes as they are pressed:

- (void)keyDown:(NSEvent *)theEvent
{
    NSLog(@"%d", [theEvent keyCode]);
}

从这段代码中，我可以很容易地看到哪些代码与某些键匹配，但我想在某个地方找到一个列出所有这些键的官方文档.我希望 Apple 在某处有一个如下所示的头文件:

From this code, I can easily see which codes match certain keys, but I would like to find an official document somewhere that lists all of them. I expected Apple to have a header file somewhere that looked like this:

enum {
    ...
    NSKeyCodeLeftArrow = 123,
    NSKeyCodeRightArrow = 124,
    ...
};

但如果有的话，我还没有找到.

But if there is one, I have yet to find it.

推荐答案

据我所知，没有枚举或键码列表.但是，要获得类似的行为，您可以在 keyDown 中调用 interpretKeyEvents:: 这将调用适当的操作方法，所有这些方法都记录在 NSResponder 中(例如 moveLeft:, insertTab: 等)

As far as I know, there is no enum or list of key codes. However, to get similar behavior, you can call interpretKeyEvents: in keyDown: which will call appropriate action methods, all of which are documented in NSResponder (e.g. moveLeft:, insertTab:, etc.)
