.SH DESCRIPTION
|
|
.LP
|
|
The core protocol does not provide any means to prevent a modifier from being
|
|
reported in events sent to clients; Xkb, however makes this possible via the
|
|
InternalMods control. It specifies modifiers that should be consumed by the
|
|
server and not reported to clients. When a key is pressed and a modifier that
|
|
has its bit set in the InternalMods control is reported to the server, the
|
|
server uses the modifier when determining the actions to apply for the key. The
|
|
server then clears the bit, so it is not actually reported to the client. In
|
|
addition, modifiers specified in the InternalMods control are not used to
|
|
determine grabs and are not used to calculate core protocol compatibility state.
|
|
|
|
Manipulate the InternalMods control via the
|
|
.I internal
|
|
field in the XkbControlsRec structure, using
|
|
.I XkbSetControls
|
|
and
|
|
.I XkbGetControls.
|
|
Alternatively, use
|
|
.I XkbSetServerInternalMods.
|
|
|
|
.I XkbSetServerInternalMods
|
|
sends a request to the server to change the internal modifiers consumed by the
|
|
server.
|
|
.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 internal modifiers control. Modifiers selected by
|
|
both
|
|
.I affect_real
|
|
and
|
|
.I real_values
|
|
are added to the server's internal modifiers control; those selected by
|
|
.I affect_real
|
|
but not by
|
|
.I real_values
|
|
are removed from the server's internal modifiers mask. 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 internal modifiers control. Modifiers
|
|
selected by both
|
|
.I affect_virtual
|
|
and
|
|
.I virtual_values
|
|
are added to the server's internal modifiers control; those selected by
|
|
.I affect_virtual
|
|
but not by
|
|
.I virtual_values
|
|
are removed from the server's internal modifiers control. See below for a
|
|
discussion of virtual modifier masks to use in
|
|
.I affect_virtual
|
|
and
|
|
.I virtual_values. XkbSetServerInternalMods
|
|
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
|
|
outlined in Figure 1.1.
|

|

.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.
