XkbAddGeomDoodad(3)			  XKB FUNCTIONS 		      XkbAddGeomDoodad(3)

       XkbAddGeomDoodad  - Add one doodad to a section of a keyboard geometry or to the top-level

       XkbDoodadPtr XkbAddGeomDoodad (XkbGeometryPtr geom, XkbSectionPtr section, Atom name);

       - geom geometry to which the doodad is added

       - section
	      section, if any, to which the doodad is added

       - name 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 dis-
       play images of keyboards can use geometry properties as hints, but  they  are  not  inter-
       preted 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 sec-
       tion.  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 func-

	   typedef union _XkbDoodad {
	       XkbAnyDoodadRec		  any;
	       XkbShapeDoodadRec	  shape;
	       XkbTextDoodadRec 	  text;
	       XkbIndicatorDoodadRec	  indicator;
	       XkbLogoDoodadRec 	  logo;
	   } XkbDoodadRec, *XkbDoodadPtr;
