XkbAddGeomOutline(3)             XKB FUNCTIONS            XkbAddGeomOutline(3)


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;
