XkbSARedirectSetVModsMask(3) XKB FUNCTIONS XkbSARedirectSetVModsMask(3)
NAME
XkbSARedirectSetVModsMask - Sets the vmods_mask0 and vmods_mask1 fields
of act from vm
SYNOPSIS
void XkbSARedirectSetVModsMask (XkbRedirectKeyAction act, unsigned int
vm);
ARGUMENTS
act action in which to set vmods
vm new value for virtual modifier mask
DESCRIPTION
Actions associated with the XkbRedirectKeyAction structure generate
KeyPress and KeyRelease events containing a keycode different from the
key that was pressed or released.
The type field for the XkbRedirectKeyAction structure should always be
XkbSA_RedirectKey. Key presses cause a KeyPress event for the key
specified by the new_key field instead of the actual key. The state re-
ported in this event reports the current effective modifiers changed as
follows: any real modifiers selected by the mods_mask field are set to
corresponding values from the mods field. Any real modifiers bound to
the virtual modifiers specified by the vmods_mask0 and vmods_mask1
fields are either set or cleared, depending on the corresponding values
in the vmods0 and vmods1 fields. If the real and virtual modifier defi-
nitions specify conflicting values for a single modifier, the real mod-
ifier definition has priority.
Key releases cause a KeyRelease event for the key specified by the
new_key field instead of the actual key. The state for this event con-
sists 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 cate-
gorizes devices by breaking them into classes. Keyboards, and other in-
put devices with keys, are classified as KeyClass devices by the input
extension.)
The vmods_mask0 and vmods_mask1 fields actually represent one
vmods_mask value. Xkb provides macros to convert between the two for-
mats.
XkbSARedirectSetVModsMask sets the vmods_mask0 and vmods_mask1 fields
of act from vm.
