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

我正在寻找可用于Cocoa的 NSEvent 类的可用键代码的完整列表。 NSEvent 类具有 keyCode 属性，定义为 unsigned short 。以下代码放置在适当的UI对象中时，将在按下时回显键代码：

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]);
}

从这个代码，我可以很容易地看到哪些代码匹配某些键，想找一份官方文件列出所有的。我预计苹果有一个头像文件在某处看起来像这样：

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,
    ...
};

但如果有一个，我还没有找到它。

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

推荐答案

据我所知，没有枚举或键列表。不过，要获得类似的行为，您可以调用 explainKeyEvents：在keyDown：将调用适当的动作方法，所有这些都记录在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.)
