NAME
XkbAddGeomOutline - Add one outline to an existing shape SYNOPSIS XkbOutlinePtr XkbAddGeomOutline (XkbShapePtr shape, int szpoints); ARGUMENTS
- shape shape to be updated
- szpoints 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 szpoints 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.
