Hi,

I tried this morning to restore lyrics editing functionality, but I
think it turns out to be harder than I thought.

The way I understand it to be meant to work is to set the
command-table of the pane; probably in the :after method in
SELECT-LAYER.  So, I did that, but it still doesn't work.

The reason it doesn't work, I think, is that the input context
established in ESA-TOP-LEVEL isn't actually left by ordinary execution
of commands -- only by running commands with mouse gestures (with,
say, presentation-to-command-translators).  So, the attached patch
(with included debugging FORMAT code) doesn't actually do the right
thing.  (It /does/ work if, after selecting a lyrics layer, the user
types C-g, because there the with-input-context _is_ reestablished.)

What's the right answer?

I forgot to mention... one other way in which this is harder than I
thought is that there is a lurking bug somewhere in McCLIM's X backend
to do with pixmaps and input focus -- I think something is trying to
set an input focus to an #<XLIB:PIXMAP ...>, which is not an
acceptable type for focus: (OR (MEMBER :POINTER-ROOT :NONE)
XLIB:WINDOW).  It's quite easy to trigger this; bringing up a
completion window or a menu over drawn areas of the score will give
you this message, and unfortunately the only solution to that error is
to exit climacs and destroy the clim port (with something like
(clim:destroy-port (car climi::*all-ports*))).

Hey ho,

Christophe
