XkbAddGeomShape(3) XKB FUNCTIONS XkbAddGeomShape(3) NAME XkbAddGeomShape - Add a shape to a keyboard geometry SYNOPSIS XkbShapePtr XkbAddGeomShape (XkbGeometryPtr geom, Atom name, int sz_out- lines); ARGUMENTS geom geometry to be updated name name of the new shape sz_outlines number of outlines to be reserved DESCRIPTION Xkb provides functions to add a single new element to the top-level key- board geometry. In each case the num_ * fields of the corresponding struc- ture 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 arbi- trary 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. A geometry contains an arbitrary number of shapes, each of which is made up of an arbitrary number of outlines. XkbAddGeomShape adds a shape to a geometry geom by allocating space for sz_outlines outlines for it and giv- ing it the name specified by name. If a shape with name name already ex- ists in the geometry, a pointer to the existing shape is returned. XkbAd- dGeomShape 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 geome- try shapes, use XkbAllocGeomShapes.
