ANY X program receives the keycodes. Look in xwin.c.

The problem is just that you are using one mapping at build time (the XKB database) but another at runtime (the current Xserver keyboard mapping). This means that you cannot trust that the keycodes are the same: They can differ in a number of cases: When the used version of the XKB database differs, when you are running another platform at runtime (say, Solaris), when you move between "normal" and "evdev" systems, if you use Xvnc etc etc. For a normal application, looking at the "keycode" is simply a big no-no. Using the "keysyms" is the preferred approach; works on all platforms.
