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
       reported 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 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
       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 vmods_mask0 and vmods_mask1 fields actually represent one vmods_mask
       value. Xkb provides macros to convert between the two formats.

       XkbSARedirectSetVModsMask sets the vmods_mask0 and vmods_mask1 fields of
       act from vm.
