XkbAddGeomDoodad − Add one doodad to a section of a keyboard geometry or to the top-level geometry
(XkbGeometryPtr geom, XkbSectionPtr
section, Atom name);
geometry to which the doodad is added
section, if any, to which the doodad is added
name of the new doodad
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.
A doodad describes some visible aspect of the keyboard that is not a key and is not a section. XkbAddGeomDoodad adds a doodad with name specified by name to the geometry geom if section is NULL or to the section of the geometry specified by section if section is not NULL. XkbAddGeomDoodad returns NULL if any of the parameters is empty or if it was not able to allocate space for the doodad. If there is already a doodad with the name name in the doodad array for the geometry (if section is NULL) or the section (if section is non-NULL), a pointer to that doodad is returned. To allocate space for an arbitrary number of doodads to a section, use the XkbAllocGeomSectionDoodads function. To allocate space for an arbitrary number of doodads to a keyboard geometry, use the XkbAllocGeomDoodads function.
