Function: tab-bar-mode

tab-bar-mode is an interactive and byte-compiled function defined in tab-bar.el.gz.

Signature

(tab-bar-mode &optional ARG)

Documentation

Toggle the tab bar in all graphical frames (Tab Bar mode).

This is a minor mode. If called interactively, toggle the Tab-Bar mode mode. If the prefix argument is positive, enable the mode, and if it is zero or negative, disable the mode.

If called from Lisp, toggle the mode if ARG is toggle. Enable the mode if ARG is nil, omitted, or is a positive number. Disable the mode if ARG is a negative number.

To check whether the minor mode is enabled in the current buffer, evaluate tab-bar-mode(var)/tab-bar-mode(fun).

The mode's hook is called both when the mode is enabled and when it is disabled.

Probably introduced at or before Emacs version 27.1.
