XkbComputeRowBounds(3)						   XKB FUNCTIONS					    XkbComputeRowBounds(3)

NAME

       XkbComputeRowBounds -  Update the bounding box of a row

SYNOPSIS

       Bool XkbComputeRowBounds (XkbGeometryPtr geom, XkbSectionPtr section, XkbRowPtr row);

ARGUMENTS

       - geom geometry that contains the section

       - section
	      section that contains the row

       - row  row to be examined and updated

DESCRIPTION

       XkbComputeRowBounds  checks  the  bounds  of all keys in the row and updates the bounding box of the row if necessary.  XkbComputeRowBounds
       returns False if any of the arguments is NULL; otherwise, it returns True.

XkbAddGeomRow(3)						   XKB FUNCTIONS						  XkbAddGeomRow(3)

NAME

       XkbAddGeomRow - Add a row to a section

SYNOPSIS

       XkbRowPtr XkbAddGeomRow (XkbSectionPtr section, int sz_keys);

ARGUMENTS

       - section
	      section to be updated

       - sz_keys
	      number of keys to be reserved

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 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.

       One of the components of a keyboard geometry section is one or more rows of keys.  XkbAddGeomRow adds one row  to  the  specified  section.
       The  newly created row contains space for the number of keys specified in sz_keys.  They are allocated and zeroed, but otherwise uninitial-
       ized.  XkbAddGeomRow returns NULL if any of the parameters is empty or if it was not able to allocate space for the row. To allocate  space
       for an arbitrary number of rows to a section, use the XkbAllocGeomRows function.

STRUCTURES

       typedef struct _XkbRow {
	       short	       top;
	       short	       left;
	       unsigned short  num_keys;
	       unsigned short  sz_keys;
	       int	       vertical;
	       XkbKeyPtr       keys;
	       XkbBoundsRec    bounds;
       } XkbRowRec, *XkbRowPtr;
