Documentation

Maximum width for automatic resizing of width of tab-bar tabs.

This determines the maximum width of tabs before their names will be truncated on display. The value should be a list of two numbers: the first is the maximum width of tabs in pixels for GUI frames, the second is the maximum width of tabs in characters on TTY frames. If the value of this variable is nil, there is no limit on maximum width. This variable has effect only when tab-bar-auto-width(var)/tab-bar-auto-width(fun) is non-nil.

This variable was added, or its default value changed, in Emacs 29.1.

Probably introduced at or before Emacs version 29.1.
