XkbAddGeomKey(3)                 XKB FUNCTIONS                XkbAddGeomKey(3)

       XkbAddGeomKey - Add one key at the end of an existing row of keys

       XkbKeyPtr XkbAddGeomKey ( row )
             XkbRowPtr row;

       - row  row to be updated

       Xkb  provides  functions  to  add a single new element to the top-level
       keyboard geometry. In each case the num_ * fields of the  corresponding
       structure  is  incremented  by  1.  These  functions do not change sz_*
       unless there is no more room in the array. Some of these functions fill
       in  the values of the element's structure from the arguments. For other
       functions, you must explicitly write code to fill the structure's  ele-

       The  top-level geometry description includes a list of geometry proper-
       ties.  A geometry property  associates  an  arbitrary  string  with  an
       equally  arbitrary  name. Programs that display images of keyboards can
       use geometry properties as hints, but they are not interpreted by  Xkb.
       No other geometry structures refer to geometry properties.

       Keys  are  grouped into rows.  XkbAddGeomKey adds one key to the end of
       the specified row.  The key is  allocated  and  zeroed.   XkbAddGeomKey
       returns  NULL  if  row is empty or if it was not able to allocate space
       for the key. To allocate space for an arbitrary number  of  keys  to  a
       row, use XkbAllocGeomKeys.

           typedef struct _XkbKey {              /* key in a row */
               XkbKeyNameRec   name;             /* key name */
               short           gap;              /* gap in mm/10 from previous key in row */
               unsigned char   shape_ndx;        /* index of shape for key */
               unsigned char   color_ndx;        /* index of color for key body */
           } XkbKeyRec, *XkbKeyPtr;
