How to set a key binding to make Emacs as transparent/opaque as I want?
- by Vivi
I want to have a command in Emacs to make it as opaque/transparent as I want (refer to the fabulous question that pointed out that transparency is possible in Emacs, and the EmacsWiki page linked there which has the code I am using below).
The EmacsWiki code sets "C-c t" to toggle the previously set transparency on and off:
;;(set-frame-parameter (selected-frame) 'alpha '(<active> [<inactive>]))
(set-frame-parameter (selected-frame) 'alpha '(85 50))
(add-to-list 'default-frame-alist '(alpha 85 50))
enter code here(eval-when-compile (require 'cl))
(defun toggle-transparency ()
(interactive)
(if (/=
(cadr (find 'alpha (frame-parameters nil) :key #'car))
100)
(set-frame-parameter nil 'alpha '(100 100))
(set-frame-parameter nil 'alpha '(85 60))))
(global-set-key (kbd "C-c t") 'toggle-transparency)
What I would like to do is to be able to choose the % transparency when I am in Emacs.
If possible, I would like a command where I type for example "C-c t N" (where N is the % opaqueness) for the active frame, and then "M-c t N" for the inactive window.
If that can't be done like that, then maybe a command where if I type "C-c t" it asks me for the number which gives the opaqueness of the active window (and the same for the inactive window using "M-c t").
Thanks in advance for your time :)
Below are just some comments that are not important to answer the question if you are not interested:
I really want this because when I told my supervisor I was learning Emacs he said TexShop is much better and that I am using software from the 80's. I told him about the wonders of Emacs and he said TexShop has all of it and more. I matched everything he showed me except for the transparency (though he couldn't match the preview inside Emacs from preview-latex). I found the transparency thing by chance, and now I want to show him Emacs rules!
I imagine this will be a piece of cake for some of you, and even though I could get it done if I spent enough time trying to learn lisp or reading around, I am not a programmer and I have only been using Emacs and a mac for a week. I am lost already as it is! So thanks in advance for your time and help - I will learn lisp eventually!
