XkbAddGeomSection(3) XKB FUNCTIONS XkbAddGeomSection(3) NAME XkbAddGeomSection - Add one section to an existing keyboard geometry SYNOPSIS XkbSectionPtr XkbAddGeomSection (XkbGeometryPtr geom, Atom name, int sz_rows, int sz_doodads, int sz_overlays); ARGUMENTS geom geometry to be updated name name of the new section sz_rows number of rows to reserve in the section sz_doodads number of doodads to reserve in the section sz_overlays number of overlays to reserve in the section DESCRIPTION Xkb provides functions to add a single new element to the top-level key- board geometry. In each case the num_ * fields of the corresponding struc- ture 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 arbi- trary 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. A keyboard geometry contains an arbitrary number of sections. XkbAddGeom- Section adds one section to an existing keyboard geometry geom. The new section contains space for the number of rows, doodads, and overlays speci- fied by sz_rows, sz_doodads, and sz_overlays. The new section is allocated and zeroed and given the name specified by name. If a section with name name already exists in the geometry, a pointer to the existing section is returned. XkbAddGeomSection returns NULL if any of the parameters is empty or if it was not able to allocate space for the section. To allocate space for an arbitrary number of sections to a geometry, use XkbAllocGeomSec- tions.
