如何在Java的KeyStroke.getKeystroke的String版本中引用mac命令键？ [英] How do you refer to the mac command key in the String version of Java's KeyStroke.getKeystroke?

问题描述

KeyStroke.getKeystroke（String）的文档（例如， getKeyStroke（control DELETE））没有提供如何访问macintosh命令键的示例，我找不到一个引用，列出了这个函数接受的修饰符，如控制的各种单词的拼写。命令键的语法是什么？

The documentation for KeyStroke.getKeystroke(String) (e.g., getKeyStroke("control DELETE")) does not provide an example of how to access the macintosh command key, and I can't find a reference that lists the spellings of the various words for modifiers like "control" that this function accepts. What is the syntax for the command key?

作为参考，这里是getKeystroke的文档：

For reference, here's the documentation for getKeystroke:

解析一个字符串并返回 KeyStroke 。
该字符串必须具有以下语法：

Parses a string and returns a KeyStroke. The string must have the following syntax:

<modifiers>* (<typedID> | <pressedReleasedID>)
  modifiers := shift | control | ctrl | meta | alt | altGraph
  typedID := typed <typedKey>
  typedKey := string of length 1 giving Unicode character.
  pressedReleasedID := (pressed | released) key
  key := KeyEvent key code name, i.e. the name following "VK_".

如果未指定键入，按下或释放，则按下。这里
是一些例子：

If typed, pressed or released is not specified, pressed is assumed. Here are some examples:

  "INSERT" => getKeyStroke(KeyEvent.VK_INSERT, 0);
  "control DELETE" => getKeyStroke(KeyEvent.VK_DELETE, InputEvent.CTRL_MASK);
  "alt shift X" => getKeyStroke(KeyEvent.VK_X, InputEvent.ALT_MASK | InputEvent.SHIFT_MASK);
  "alt shift released X" => getKeyStroke(KeyEvent.VK_X, InputEvent.ALT_MASK | InputEvent.SHIFT_MASK, true);
  "typed a" => getKeyStroke('a');

推荐答案

我不得不去AWTKeyStroke的源代码getAWTKeyStroke（String s）来查看全部可接受的修饰词术语，然后做一些试验和错误，检查命令键的修饰语法是meta。

I had to go to the source code for AWTKeyStroke getAWTKeyStroke(String s) to see all of the acceptable modifier terms, and then do a little trial and error, to check that the modifier syntax for the command key is "meta".
