mask of real modifiers affected by this call

.SH DESCRIPTION
.LP
The core protocol does not provide a way to exclude specific modifiers from grab
calculations, with the result that locking modifiers sometimes have
unanticipated side effects.
The IgnoreLockMods control specifies modifiers that should be excluded from grab
calculations. These modifiers are also not reported in any core events except
KeyPress and KeyRelease events that do not activate a passive grab and that do
not occur while a grab is active.
Manipulate the IgnoreLockMods control via the
.I ignore_lock
field in the XkbControlsRec structure, then use
.I XkbSetControls
and
.I XkbGetControls
to query and change this control. Alternatively, use
.I XkbSetIgnoreLockMods.
.I XkbSetIgnoreLockMods
sends a request to the server to change the server's IgnoreLockMods control.
.I affect_real
and
.I real_values
are masks of real modifier bits indicating which real modifiers are to be added
and removed from the server's IgnoreLockMods control. Modifiers selected by both
.I affect_real
and
.I real_values
are added to the server's IgnoreLockMods control; those selected by
.I affect_real
but not by
.I real_values
are removed from the server's IgnoreLockMods control. Valid values for
.I affect_real
and
.I real_values
consist of any combination of the eight core modifier bits: ShiftMask, LockMask,
ControlMask, Mod1Mask - Mod5Mask.
.I affect_virtual
and
.I virtual_values
are masks of virtual modifier bits indicating which virtual modifiers are to be
added and removed from the server's IgnoreLockMods control. Modifiers selected
by both
.I affect_virtual
and
.I virtual_values
are added to the server's IgnoreLockMods control; those selected by
.I affect_virtual
but not by
.I virtual_values
are removed from the server's IgnoreLockMods control. See below for a discussion
of virtual modifier masks to use in
.I affect_virtual
and
.I virtual_values. XkbSetIgnoreLockMods
does not wait for a reply from the server. It returns True if the request was
sent, and False otherwise.
Virtual modifiers are named by converting their string name to an X Atom and
storing the Atom in the
.I names.vmods
array in an XkbDescRec structure. The position of a name Atom in the
.I names.vmods
array defines the bit position used to represent the virtual modifier and also
the index used when accessing virtual modifier information in arrays: the name
in the i-th (0 relative) entry of
.I names.vmods
is the i-th virtual modifier, represented by the mask (1<<i). Throughout Xkb,
various functions have a parameter that is a mask representing virtual modifier
choices. In each case, the i-th bit (0 relative) of the mask represents the i-th
virtual modifier.
To set the name of a virtual modifier, use
.I XkbSetNames,
using XkbVirtualModNamesMask in
.I which
and the name in the
.I xkb
argument; to retrieve indicator names, use
.I XkbGetNames.
.SH STRUCTURES
.LP
The complete description of an Xkb keyboard is given by an XkbDescRec. The
component structures in the XkbDescRec represent the major Xkb components.
.nf
typedef struct {
struct _XDisplay * display; /\(** connection to X server */
unsigned short flags; /\(** private to Xkb, do not modify */
unsigned short device_spec; /\(** device of interest */
KeyCode min_key_code; /\(** minimum keycode for device */
KeyCode max_key_code; /\(** maximum keycode for device */
XkbControlsPtr ctrls; /\(** controls */
XkbServerMapPtr server; /\(** server keymap */
XkbClientMapPtr map; /\(** client keymap */
XkbIndicatorPtr indicators; /\(** indicator map */
XkbNamesPtr names; /\(** names for all components */
XkbCompatMapPtr compat; /\(** compatibility map */
XkbGeometryPtr geom; /\(** physical geometry of keyboard */
} XkbDescRec, *XkbDescPtr;
.fi
The display field points to an X display structure. The flags field is private
to the library: modifying flags may yield unpredictable results. The device_spec
field specifies the device identifier of the keyboard input device, or
XkbUseCoreKeyboard, which specifies the core keyboard device. The min_key_code
and max_key_code fields specify the least and greatest keycode that can be
returned by the keyboard.
Each structure component has a corresponding mask bit that is used in function
calls to indicate that the structure should be manipulated in some manner, such
as allocating it or freeing it. These masks and their relationships to the
fields in the XkbDescRec are shown in Table 1.
