DESCRIPTION

21       Xkb provides functions to add a single new  element  to  the  top-level
22       keyboard  geometry. In each case the num_ * fields of the corresponding
23       structure is incremented by 1. These functions do not change  sz_*  un‐
24       less  there  is no more room in the array. Some of these functions fill
25       in the values of the element's structure from the arguments. For  other
26       functions,  you must explicitly write code to fill the structure's ele‐
27       ments.
28
29       The top-level geometry description includes a list of geometry  proper‐
30       ties.   A  geometry  property  associates  an  arbitrary string with an
31       equally arbitrary name. Programs that display images of  keyboards  can
32       use  geometry properties as hints, but they are not interpreted by Xkb.
33       No other geometry structures refer to geometry properties.
34
35       XkbAddGeomOverlayKey adds one key to the row in the overlay.  If  there
36       is  no key named under in the row of the underlying section, XkbAddGeo‐
37       mOverlayKey returns NULL.
