19 Xkb provides functions to add a single new element to the top-level
20 keyboard geometry. In each case the num_ * fields of the corresponding
21 structure is incremented by 1. These functions do not change sz_* un‐
22 less there is no more room in the array. Some of these functions fill
23 in the values of the element's structure from the arguments. For other
24 functions, you must explicitly write code to fill the structure's ele‐
25 ments.
26 The top-level geometry description includes a list of geometry proper‐
28 ties. A geometry property associates an arbitrary string with an
29 equally arbitrary name. Programs that display images of keyboards can
30 use geometry properties as hints, but they are not interpreted by Xkb.
31 No other geometry structures refer to geometry properties.
32 One of the components of a keyboard geometry section is one or more
34 rows of keys. XkbAddGeomRow adds one row to the specified section.
35 The newly created row contains space for the number of keys specified
36 in sz_keys. They are allocated and zeroed, but otherwise uninitial‐
37 ized. XkbAddGeomRow returns NULL if any of the parameters is empty or
38 if it was not able to allocate space for the row. To allocate space for
39 an arbitrary number of rows to a section, use the XkbAllocGeomRows
40 function.
