NAME
XkbAddGeomOverlayRow - Add a row to an existing overlay SYNOPSIS XkbOverlayRowPtr XkbAddGeomOverlayRow (XkbOverlayPtr overlay, XkbRowPtr rowunder, int szkeys); ARGUMENTS
- overlay overlay to be updated
- rowunder row to be overlayed in the section overlay overlays
- szkeys number of keys to reserve in the row 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. XkbAddGeomOverlayRow adds one row to the overlay. The new row contains space for szkeys keys. If rowunder specifies a row that doesn't exist on the underlying section, XkbAddGeomOverlayRow returns NULL and doesn't change the overlay. XkbAddGeomOverlayRow returns NULL if any of the parameters is empty or if it was not able to allocate space for the overlay.
