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_doo-
	      dads, 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 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  keyboard geometry contains an arbitrary number of sections.  XkbAddGeomSection adds one
       section to an existing keyboard geometry geom.  The new section	contains  space  for  the
       number  of  rows, doodads, and overlays specified by sz_rows, sz_doodads, and sz_overlays.
       The new section is allocated and zeroed and given the name specified by name.  If  a  sec-
       tion  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 XkbAllocGeomSections.

STRUCTURES
       typedef struct _XkbSection {
	   Atom 		   name;	/* section name */
	   unsigned char	   priority;	/* drawing priority, 0=>highest, 255=>lowest */
	   short		   top; 	/* top coordinate of section origin */
	   short		   left;	/* left coordinate of row origin */
	   unsigned short	   width;	/* section width, in mm/10 */
	   unsigned short	   height;	/* section height, in mm/10 */
	   short		   angle;	/* angle of section rotation, counterclockwise */
	   unsigned short	   num_rows;	/* number of rows in the rows array */
	   unsigned short	   num_doodads; /* number of doodads in the doodads array */
	   unsigned short	   num_overlays; /* number of overlays in the overlays array */
	   unsigned short	   sz_rows;	 /* size of the rows array */
	   unsigned short	   sz_doodads;	 /* size of the doodads array */
	   unsigned short	   sz_overlays;  /* size of the overlays array */
	   XkbRowPtr		   rows;	 /* section rows array */
	   XkbDoodadPtr 	   doodads;	 /* section doodads array */
	   XkbBoundsRec 	   bounds;	 /* bounding box for the section, before rotation*/
	   XkbOverlayPtr	   overlays;	 /* section overlays array */
       } XkbSectionRec, *XkbSectionPtr;

       top and left are the origin of the section, relative to the origin  of  the  keyboard,  in
       mm/10. angle is in 1/10 degrees.
