- ;;; Commentary:
-
- ;; win32-win.el: this file is loaded from ../lisp/startup.el when it recognizes
- ;; that win32 windows are to be used. Command line switches are parsed and those
- ;; pertaining to win32 are processed and removed from the command line. The
- ;; win32 display is opened and hooks are set for popping up the initial window.
-
- ;; startup.el will then examine startup files, and eventually call the hooks
- ;; which create the first window (s).
-
- ;;; Code:
-
-
- ;; These are the standard X switches from the Xt Initialize.c file of
- ;; Release 4.
-
- ;; Command line Resource Manager string
-
- ;; +rv *reverseVideo
- ;; +synchronous *synchronous
- ;; -background *background
- ;; -bd *borderColor
