NAME

       XkbSAPtrDfltValue - Returns the valueXXX field of act converted to a signed int

SYNOPSIS

       int XkbSAPtrDfltValue (XkbAction act);

ARGUMENTS

       - act  action from which to extract group

DESCRIPTION

       Actions associated with the XkbPtrDfltAction structure change the mk_dflt_btn attribute of
       the MouseKeys control.

       If the MouseKeys control is not enabled, KeyPress and KeyRelease  events  are  treated  as
       though  the  action  is  XkbSA_NoAction.  Otherwise,  this  action changes the mk_dflt_btn
       attribute of the MouseKeys control.

       The type field of the XkbPtrDfltAction structure should always be XkbSA_SetPtrDflt.

       The flags field is composed of the bitwise inclusive OR of the values  shown  in  Table  1
       (currently there is only one value defined).

                        Table 1 Pointer Default Flags
       ─────────────────────────────────────────────────────────────────
       Flag                    Meaning
       ─────────────────────────────────────────────────────────────────
       XkbSA_DfltBtnAbsolute   If  set,  the  value field represents an
                               absolute pointer button. Otherwise,  the
                               value  field represents the amount to be
                               added to the current default button.

       The affect field specifies what changes as a result of this action. The only  valid  value
       for the affect field is XkbSA_AffectDfltBtn.

       The  valueXXX  field  is  a  signed character that represents the new button value for the
       mk_dflt_btn attribute of the MouseKeys control. If XkbSA_DfltBtnAbsolute is set in  flags,
       valueXXX  specifies  the button to be used; otherwise, valueXXX specifies the amount to be
       added to the current default button. In either case, illegal button  choices  are  wrapped
       back  around  into  range.  Xkb provides macros, to convert between the integer and signed
       character values in XkbPtrDfltAction structures.

       XkbSAPtrDfltValue returns the valueXXX field of act converted to a signed int.
