Setting emacs font under windows

Question

I'm having trouble to change the font for my emacs configuration. I've tried using set-default-font, and managed to tab to my desired font, however, some elements are still rendered as the old font (ie python's class names and function names)

Answer 1

set-default-font is really old, and has been deprecated in Emacs 23 in favor of its new name set-frame-font (which isn't much better). The current Emacs manual suggests several ways to set the default font, but I'll assume you've found those already, seeing as you've tried set-default-font...

The elisp code I use is actually different from all the methods suggested there:

;; [in .emacs]
;; Use 10-pt Consolas as default font
(set-face-attribute 'default nil
                    :family "Consolas" :height 100)

set-face-attribute seems to stick better than set-default-font; at least it seems to use Consolas consistently even in things like Python class and function names.

Answer 2

M-x customize-face default will let you customize the default font.

If some things are still rendered in a font you don't like, then position your cursor to be over the offending text and type M-x customize-face; the face that your cursor is over will be the default one to customize.
