.TH XkbSARedirectVMods __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
.SH NAME
XkbSARedirectVMods \- Returns the vmods0 and vmods1 fields of act converted to
an unsigned int
.SH SYNOPSIS
.HP
.B unsigned int XkbSARedirectVMods
.BI "(\^XkbRedirectKeyAction " "act" "\^);"
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- act
action from which to extract vmods
.SH DESCRIPTION
.LP
Actions associated with the XkbRedirectKeyAction structure generate KeyPress and
KeyRelease events
containing a keycode different from the key that was pressed or released.
The
.I type
field for the XkbRedirectKeyAction structure should always be XkbSA_RedirectKey.
Key presses cause a KeyPress event for the key specified by the
.I new_key
field instead of the actual key. The state reported in this event reports the
current effective
modifiers changed as follows: any real modifiers selected by the
.I mods_mask
field are set to corresponding values from the
.I mods
field. Any real modifiers bound to the virtual modifiers specified by the
.I vmods_mask0
and
.I vmods_mask1
fields are either set or cleared, depending on the corresponding values in the
.I vmods0
and
.I vmods1
fields. If the real and virtual modifier definitions specify conflicting values
for a single modifier,
the real modifier definition has priority.
Key releases cause a KeyRelease event for the key specified by the
.I new_key
field instead of the actual key. The state for this event consists of the
effective keyboard modifiers
at the time of the release, changed as described previously.
The XkbSA_RedirectKey action normally redirects to another key on the same
device as the key that
caused the event, unless that device does not belong to the input extension
KeyClass, in which case
this action causes an event on the core keyboard device. (The input extension
categorizes devices by
breaking them into classes. Keyboards, and other input devices with keys, are
classified as KeyClass
devices by the input extension.)
The
.I vmods_mask0
and
.I vmods_mask1
fields actually represent one
.I vmods_mask
value. Xkb provides macros to convert between the two formats.
.I XkbSARedirectVModsMask
returns the
.I vmods0
and
.I vmods1
fields of
.I act
converted to an unsigned int.
