Comment (by simonsouth):
The input-filter mechanism isn't nearly as flexible as I imagined and
won't be of use here.
What I have done is follow Jérôme's suggestion and create a patch that
makes the Input Server notify applications when a new key map has been
loaded, using a newly defined message, B_KEY_MAP_LOADED:
https://review.haiku-os.org/c/haiku/+/1741
(Note B_KEY_MAP_CHANGED is [https://www.haiku-os.org/legacy-
docs/bebook/TheInputServer_Messages.html#KeyboardDeviceControlMessages
already taken].) The patch uses BRoster::Broadcast() to send the message
to every application that's running. This appears safe and seems to work
fine, but I'm open to feedback if there's a better approach.
I've also updated my patch for Terminal to have TermApp simply listen for
B_KEY_MAP_LOADED and forward the message to its TermWindow when it
arrives. This allows the node monitor to be dispensed with altogether, and
feels like a much more elegant solution. Those changes can be seen here:
