当我启动emacs时，我可以使用--title=选项来控制包含emacs应用程序的x窗口的标题。是否可能从elisp更改标题后启动emacs？
M-x set-frame-name NewName RET
以及从elisp
(set-frame-name "NewName")
我使用
(setq frame-title-format "%b - emacs")
将目前的缓冲名称列入框架名称。
以下是我使用的方法（在Cygwin多窗口X11上使用GNU EMACS 24.3.1）：
(set-frame-parameter frame title arg)
我将其包装在一个交互式函数中。
(defun set-frame-title/ag (title &optional frame)
"set frame TITLE of &optional FRAME defaults to (selected-frame)
aka C11 window titlebar name"
(interactive "sframe title: ")
(set-frame-parameter frame title title)
)
