|
|
583
|
|
584 Each element of `sound-alist' is a list describing a sound.
|
|
585 The first element of the list is the name of the sound being defined.
|
|
586 Subsequent elements of the list are alternating keyword/value pairs:
|
|
587
|
|
588 Keyword: Value:
|
|
589 ------- -----
|
|
590 sound A string of raw sound data, or the name of another sound to
|
|
591 play. The symbol `t' here means use the default X beep.
|
|
592 volume An integer from 0-100, defaulting to `bell-volume'
|
|
593 pitch If using the default X beep, the pitch (Hz) to generate.
|
|
594 duration If using the default X beep, the duration (milliseconds).
|

595
|
|
596 For compatibility, elements of `sound-alist' may also be:

599 ( sound-name <volume> <sound> )

603
|

604 Caveats:
|
|
605 - XEmacs must be built with sound support for your system. Not all
|
|
606 systems support sound.
|
|
607
|
|
608 - The pitch, duration, and volume options are available everywhere, but
|
|
609 many X servers ignore the `pitch' option.
|
|
610
|
|
611 The following beep-types are used by emacs itself:
|
|
612
|
|
613 auto-save-error when an auto-save does not succeed
|
|
614 command-error when the emacs command loop catches an error
|
|
615 undefined-key when you type a key that is undefined
|
|
616 undefined-click when you use an undefined mouse-click combination
|
|
617 no-completion during completing-read
|
|
618 y-or-n-p when you type something other than 'y' or 'n'
|
|
619 yes-or-no-p when you type something other than 'yes' or 'no'
|
|
620 default used when nothing else is appropriate.
|
|
621
|
|
622 Other lisp packages may use other beep types, but these are the ones that
|
|
623 the C kernel of Emacs uses.
