1. NAME▲
XkbGetStickyKeysOptions - Queries the current StickyKeys attributes for a keyboard device
2. SYNOPSIS ▲
Bool XkbGetStickyKeysOptions (Display * display , unsigned int device_spec , unsigned int * options_rtrn );
3. ARGUMENTS ▲
- - display
connection to X server - - device_spec
device ID, or XkbUseCoreKbd - - options_rtrn
backfilled with StickyKeys option mask
4. DESCRIPTION ▲
The StickyKeys control has two options that can be accessed via the ax_optionsof an XkbControlsRec structure. The first option, TwoKeys, specifies whether StickyKeys should automatically turn off when two keys are pressed at the same time. This feature is useful for shared computers so people who do not want them do not need to turn StickyKeys off if a previous user left StickyKeys on. The second option, LatchToLock, specifies whether or not StickyKeys locks a modifier when pressed twice in a row. XkbGetStickyKeysOptionsrequests the attributes of the StickyKeys control from the server, waits for a reply, and backfills options_rtrnwith a mask indicating whether the individual StickyKeys options are on or off. Valid bits in options_rtrnare:
XkbAX_TwoKeysMask
XkbAX_LatchToLockMask
XkbGetStickyKeysOptionsreturns True if successful; if a compatible version of the Xkb extension is not available in the server XkbGetStickyKeysOptionsreturns False.
5. RETURN VALUES ▲
- True
The XkbGetStickyKeysOptionsfunction returns True if the request for the attributes of the StickyKeys control from the server was successful. - False
The XkbGetStickyKeysOptionsfunction returns False if a compatible version of the Xkb extension is not available in the server.
6. STRUCTURES ▲
The XkbControlsRec structure is defined as follows:
#define XkbMaxLegalKeyCode 255
#define XkbPerKeyBitArraySize ((XkbMaxLegalKeyCode+1)/8)
