NAME

       XkbSetDetectableAutoRepeat - Sets DetectableAutoRepeat


SYNOPSIS

              *supported_rtrn);


ARGUMENTS

       display
              connection to X server

       detectable

       supported_rtrn
              backfilled True if DetectableAutoRepeat supported


DESCRIPTION

       Auto-repeat is the generation of multiple key events by a keyboard when
       the user presses a key and holds it down. Keyboard hardware and device-
       dependent X server software often implement auto-repeat by generating
       multiple KeyPress events with no intervening KeyRelease event. The
       standard behavior of the X server is to generate a KeyRelease event for
       every KeyPress event. If the keyboard hardware and device-dependent
       software of the X server implement auto-repeat by generating multiple
       KeyPress events, the device-independent part of the X server by default
       synthetically generates a KeyRelease event after each KeyPress event.
       This provides predictable behavior for X clients, but does not allow
       those clients to detect the fact that a key is auto-repeating.

       Xkb allows clients to request detectable auto-repeat.  If a client
       requests and the server supports DetectableAutoRepeat, Xkb generates
       KeyRelease events only when the key is physically released. If
       DetectableAutoRepeat is not supported or has not been requested, the
       server synthesizes a KeyRelease event for each repeating KeyPress event
       it generates.

       DetectableAutoRepeat, unlike other controls, is not contained in the
       XkbControlsRec structure, nor can it be enabled or disabled via the
       EnabledControls control. Instead, query and set DetectableAutoRepeat
       using XkbGetDetectableAutoRepeat and XkbSetDetectableAutoRepeat.

       DetectableAutoRepeat is a condition that applies to all keyboard devices
       for a client's connection to a given X server; it cannot be selectively
       set for some devices and not for others. For this reason, none of the Xkb
       library functions involving DetectableAutoRepeat involve a device
       specifier.

       This request affects all keyboard activity for the requesting client
       only; other clients still see the expected nondetectable auto-repeat
       behavior, unless they have requested otherwise.

       XkbSetDetectableAutoRepeat sends a request to the server to set
       DetectableAutoRepeat on for the current client if detectable is True, and
       off if detectable is False; it then waits for a reply. If supported_rtrn
       is not NULL, XkbSetDetectableAutoRepeat backfills supported_rtrn with
       True if the server supports DetectableAutoRepeat, and False if it does
       not.  XkbSetDetectableAutoRepeat returns the current state of
       DetectableAutoRepeat for the requesting client: True if
       DetectableAutoRepeat is set, and False otherwise.


RETURN VALUES

       True           The XkbSetDetectableAutoRepeat function returns True if
                      DetectableAutoRepeat is set.

       False          The XkbSetDetectableAutoRepeat function returns False if
                      DetectableAutoRepeat is not set.
