(use-theme theme #&key (for-windows #t) (for-menus #t) (for-icons #t) (for-background #t) (for-global-settings #t))
Use settings from THEME to set up the window manager. THEME can be either a theme object (as returned by load-theme) or a string naming a theme, in which case that theme will be loaded and used. By default, window styles, menus, icons, backgrounds, and global settings are all affected; if the FOR-WINDOWS, FOR-MENUS, FOR-ICONS, FOR-BACKGROUND, or FOR-GLOBAL-SETTINGS arguments are #f, the corresponding areas are not affected. (Note: at this time, only windows and backgrounds are affected; the other components of themes have yet to be implemented.)
