If any controls were just enabled or disabled (that is, the contents of +the +.I enabled_ctrls +field changed), they are flagged in the +.I enabled_ctrl_changes +field. The valid bits for these fields are the masks listed in Table 10.7 with +"ok" in the +.I enabled_ctrls +column. The +.I num_groups +field reports the number of groups bound to the key belonging to the most number +of groups and is automatically updated when the keyboard mapping changes. + +If the change was caused by a request from a client, the +.I keycode +and +.I event_type +fields are set to zero and the +.I req_major +and +.I req_minor +fields identify the request. The +.I req_major value is the same as the major extension opcode. Otherwise, +.I event_type +is set to the type of event that caused the change (one of KeyPress, KeyRelease, +DeviceKeyPress, DeviceKeyRelease, ButtonPress or ButtonRelease), and +.I req_major +and +.I req_minor +are undefined. If +.I event_type +is KeyPress, KeyRelease, DeviceKeyPress, or DeviceKeyRelease, the +.I keycode +field is set to the key that caused the change. If +.I event_type +is ButtonPress or ButtonRelease, +.I keycode +contains the button number. + +When a client receives an XkbControlsNotify event, it can note the changes in a +changes structure using +.I XkbNoteControlsChanges. + +.I XkbGetControlsChanges +examines the +.I changes +parameter, queries the server for the necessary information, and copies the +results into the +.I xkb->ctrls +keyboard description. If the +.I ctrls +field of +.I xkb +is NULL, +.I XkbGetControlsChanges +allocates and initializes it. To free the +.I ctrls +field, use +XkbFreeControls. + +.I XkbGetControlsChanges +returns Success if successful and can generate BadAlloc, BadImplementation, and +BadMatch errors. +.SH "RETURN VALUES" +.TP 15 +Success +The +.I XkbGetControlsChanges +function returns Success if the query of the server was successful. +.SH STRUCTURES +.LP +.nf +The structure for the XkbControlsNotify event is defined as follows: + +typedef struct { + int type; /\(** Xkb extension base event code */ + unsigned long serial; /\(** X server serial number for event */ + Bool send_event; /\(** True => synthetically generated */ + Display * display; /\(** server connection where event generated */ + Time time; /\(** server time when event generated */ + int xkb_type; /\(** XkbCompatMapNotify */ + int device; /\(** Xkb device ID, will not be XkbUseCoreKbd */ + unsigned int changed_ctrls; /\(** bits indicating which controls data have +changed*/ + unsigned int enabled_ctrls; /\(** controls currently enabled in server */ + unsigned int enabled_ctrl_changes; /\(** bits indicating enabled/disabled +controls */ + int num_groups; /\(** current number of keyboard groups */ + KeyCode keycode; /\(** != 0 => keycode of key causing change */ + char event_type; /\(** Type of event causing change */ + char req_major; /\(** major event code of event causing change */ + char req_minor; /\(** minor event code of event causing change */ +} XkbControlsNotifyEvent; +.fi +.SH DIAGNOSTICS +.TP 15 +.B BadAlloc +Unable to allocate storage +.TP 15 +.B BadImplementation +Invalid reply from server +.TP 15 +.B BadMatch +A compatible version of Xkb was not available in the server or an argument has +correct type and range, but is otherwise invalid +.SH "SEE ALSO" +.BR XkbFreeControls (__libmansuffix__), +.BR XkbNoteControlsChanges (__libmansuffix__), +.BR XkbSelectEventDetails (__libmansuffix__), +.BR XkbSelectEvents (__libmansuffix__) |
