1. NAME▲

XkbAddGeomOverlayKey - Add a key to an existing overlay row

2. SYNOPSIS ▲

XkbOverlayKeyPtr XkbAddGeomOverlayKey (XkbOverlayPtr overlay , XkbRowPtr row , char * under );

3. ARGUMENTS ▲

  • - overlay
        overlay to be updated
  • - row
        row in overlay to be updated
  • - under
        primary name of the key to be considered

4. 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. XkbAddGeomOverlayKeyadds one key to the rowin the overlay.If there is no key named underin the row of the underlying section, XkbAddGeomOverlayKeyreturns NULL.
