XkbGetDetectableAutoRepeat(3) XKB FUNCTIONS XkbGetDetectableAutoRepeat(3)
NAME
XkbGetDetectableAutoRepeat - Determines whether or not the server supports DetectableAu-
toRepeat
SYNOPSIS
Bool XkbGetDetectableAutoRepeat (Display *display, Bool *supported_rtrn);
ARGUMENTS
- display
connection to X server
- 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 KeyRe-
lease 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-indepen-
dent 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 physi-
cally 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 struc-
ture, nor can it be enabled or disabled via the EnabledControls control. Instead, query
and set DetectableAutoRepeat using XkbGetDetectableAutoRepeat and XkbSetDetectableAutoRe-
peat.
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.
XkbGetDetectableAutoRepeat queries the server for the current state of DetectableAutoRe-
peat and waits for a reply. If supported_rtrn is not NULL, it backfills supported_rtrn
with True if the server supports DetectableAutoRepeat, and False otherwise. XkbGetDe-
tectableAutoRepeat returns the current state of DetectableAutoRepeat for the requesting
client: True if DetectableAutoRepeat is set, and False otherwise.
RETURN VALUES
True The XkbGetDetectableAutoRepeat function returns True if the server supports
DetectableAutoRepeat.
False The XkbGetDetectableAutoRepeat function returns False if the server does
not support DetectableAutoRepeat.
