In GTK versions of Emacs (or more generally any GUI version of Emacs), can the scrollbar and menubar colors be customized? I can probably change the look of ALL my GTK applications, but when running Emacs with a dark theme I might want to ONLY change Emacs' appearance. Is this possible?
Barring any other answers, which are endemic to Emacs, I actually found one way to change the theme per app:
GTK_THEME=<your_theme> emacs
This will launch Emacs with the specified theme, assuming you are running GTK based Emacs. Other platforms won't allow this exact workaround, obviously.
For hiding the menu bar and scroll bar in emacs, just add these two lines in your init.el file in .emacs.d directory
;; For hiding menu bar
(menu-bar-mode -1)
;; For hiding scroll bar
(toggle-scroll-bar -1)
