NAME

       XkbAddGeomOutline - Add one outline to an existing shape

SYNOPSIS

       XkbOutlinePtr XkbAddGeomOutline (XkbShapePtr shape, int sz_points);

ARGUMENTS

       - shape
              shape to be updated

       - sz_points
              number of points 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.

       An outline consists of an arbitrary number of points.  XkbAddGeomOutline adds an outline to the specified
       shape  by  reserving sz_points points for it. The new outline is allocated and zeroed.  XkbAddGeomOutline
       returns NULL if any of the parameters is empty or if it was not able to allocate space. To allocate space
       for an arbitrary number of outlines to a shape, use XkbAllocGeomOutlines.

STRUCTURES

           typedef struct _XkbOutline {
               unsigned short    num_points;      /∗ number of points in the outline */
               unsigned short    sz_points;       /∗ size of the points array */
               unsigned short    corner_radius;   /∗ draw corners as circles with this radius */
               XkbPointPtr       points;          /∗ array of points defining the outline */
           } XkbOutlineRec, *XkbOutlinePtr;
