NAME¶
XkbAddGeomKey - Add one key at the end of an existing row of keys
SYNOPSIS¶
XkbKeyPtr XkbAddGeomKey (XkbRowPtr
  row);
ARGUMENTS¶
  - - row
 
  - row to be updated
 
DESCRIPTION¶
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 elements.
The top-level geometry description includes a list of 
geometry
  properties. 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.
STRUCTURES¶
    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;
