bionic (3) XkbSAPtrDfltValue.3.gz

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.
