DESCRIPTION

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