XkbSetDetectableAutoRepeat(3) XKB FUNCTIONS XkbSetDetectableAutoRepeat(3) NAME XkbSetDetectableAutoRepeat - Sets DetectableAutoRepeat SYNOPSIS Bool XkbSetDetectableAutoRepeat (Display *display, Bool detectable, Bool *supported_rtrn); ARGUMENTS display connection to X server detectable True => set DetectableAutoRepeat 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 re- quests and the server supports DetectableAutoRepeat, Xkb generates KeyRelease events only when the key is physically released. If De- tectableAutoRepeat 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 En- abledControls control. Instead, query and set DetectableAutoRepeat us- ing XkbGetDetectableAutoRepeat and XkbSetDetectableAutoRepeat. DetectableAutoRepeat is a condition that applies to all keyboard de- vices for a client's connection to a given X server; it cannot be se- lectively set for some devices and not for others. For this reason, none of the Xkb library functions involving DetectableAutoRepeat in- volve 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 De- tectableAutoRepeat on for the current client if detectable is True, and off if detectable is False; it then waits for a reply. If sup- ported_rtrn is not NULL, XkbSetDetectableAutoRepeat backfills sup- ported_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 De- tectableAutoRepeat 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.
