XkbAddGeomOutline(3)             XKB FUNCTIONS            XkbAddGeomOutline(3)



NAME
       XkbAddGeomOutline - Add one outline to an existing shape

SYNOPSIS
       XkbOutlinePtr XkbAddGeomOutline ( shape, sz_points )
             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  ele-
       ments.

       The  top-level geometry description includes a list of geometry proper-
       ties.  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.  XkbAddGeomOut-
       line adds an outline to the  specified  shape  by  reserving  sz_points
       points for it. The new outline is allocated and zeroed.  XkbAddGeomOut-
       line 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;
