[mythtv] How to send a key event from MythLineEdit?

[zoiks2004-ivtv at yahoo.com]

Thanks, Korey

OK, I tried making the replacement 0->65 for both
methods, but it still doesn't work.  It still acts as
if the key event is never even sent - it's just
ignored altogether.

There is also a customEvent method in MythMainWindow
that is capable of generating key events, but I can't
seem to access it from MythLineEdit because the method
is protected.  (I used somethingn like
gContext->GetMainWindow()->customEvent(key)).

You'll have to forgive me for the stupid questions;
I'm not much of a programmer/hacker.
