That would be the best solution but we would need an "LFUN manager" that
will receive the different signals and properly enable/disable the
associated LFUN. That could be LyXFunc of course :-)
I think this means that many places of the code have to be aware of
what lfuns exist. For example move-paragraph-up is disabled at the top
of the document. Does it mean that every time the cursor is moved, one
has to emit a 'i am at the top of the document' signal?
No, only a 'paragraph changed' signal will do. Checking if we are at top
or not would be the duty of the LyXFunc slot for this signal.
Are we going
to declare a new signal for each and every situation that might be
relevant to some lfun?
No, we have to think of grouping relevant LFUNs together. This grouping
task is more or less done anyway.
