选择窗口时请执行操作 [英] Do stuff when selecting a window

问题描述

我一直在查看可用的钩子，但是当您切换窗口时，似乎没有任何人触发。

I've been looking through the available hooks, but none of them seems to be firing when you switch windows.

我正在尝试的是为所选窗口激活一个次要模式：

What I'm trying to do, is activating a minor mode for the selected window:

(defvar active-window (frame-selected-window))

(defun active-window-switch (&rest _)
  (when active-window
    (with-selected-window active-window
      (active-window-mode nil)))
  (setq active-window (frame-selected-window))
  (active-window-mode t))

(define-minor-mode active-window-mode
  "Minor mode to distinguish the selected window."
  :global nil :group 'active-window :init-value nil :lighter " Active")

(add-hook 'window-configuration-change-hook #'active-window-switch)

(provide 'active-window)

我可以使用什么钩子或功能来代替 window-configuration-change-hook （仅当我创建或退出窗口时才会触发）？

What hook or function to advice can I use instead of window-configuration-change-hook (which only fires when I create or quit windows)?

推荐答案

select-window 是一种内部使用的操作，在单一命令中潜在数千次。你一直都不关心所选的窗口，而只是在不运行命令的时候。所以钩住自己的好地方在 post-command-hook 。

select-window is an operation used internally in many cases, potentially thousands of times in a single command. You don't really care about the selected window all the time, but only when not running a command. So the better place to hook yourself is in post-command-hook.
