Hi all,

Here's some infrastructure to allow layouts to define window decorations such as tabs or title bars. I'm mostly sending it in to get comments. I soon hope to have a crude tabbed layout using this.

I think we should leverage the existing layout/message system as much as possible here. Proposed modifications: - instance Message XEvent - dispatch unhandled XEvents to layouts - add another message type: data ViewMsg = View | Hide -- send this message to layouts on workspace change - put modifyLayout in the X monad

This does sound like a better approach.

This should give us enough flexibility to do decorations inside layouts without polluting the core with decoration handling.

That still doesn't give us any way to delete decorations when they are no longer needed. At a minimum we'd also need to send an event/message when we want to switch layouts. The user could always do this in his/her config file, but it'd be nicer for layout writers to not put this burden on their users, and to be able to rely on *always* getting notified when they are no longer in control of the screen (and thus need to clean up anything they've stuck on it). -- David Roundy http://www.darcs.net
