.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 */
|
|

|

} 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.
