It turns out this problem never happens if I only call START-APP from the listener. As soon as I call it from the LispWorks editor, something happens that prevents me from calling START-APP again. It seems like the main difference between evaluating a form at the listener and in the editor is that LispWorks starts a new thread for forms evaluated in the editor. Perhaps this interferes with Gtk somehow. I can at least get some work done with this:
(defun gtk-demo (&optional dbg) (unless (search "Listener" (mp:process-name mp:*current-process*)) (error "Run only from the listener")) (cells-gtk-init) (cells-gtk:start-app 'tets-gtk :debug dbg)) but that's not solving the problem. If this (i.e. spawning a new thread to run gtk-main breaking future calls to it) rings a bell with anyone, let me know. I'll post here if I find something that works.

I coded the use of restarts in that code. Despite reading up abot restarts in Practical Common Lisp, I still don't think I quite understand them. So that code is suspect, especially because it has #+lispworks in it. Maybe you could try the code in start-app that currently is #-lispworks. It simply runs gtk-main. The idea of the the #+lispworks alternative (stuff with process-wait-with-timeout) is to give other processes (slime in particular) a chance to run. I don't have LW 5.0 yet so I probably can't be much help. -- - Best regards, Peter _______________________________________________ cells-gtk-devel site list [email protected] http://common-lisp.net/mailman/listinfo/cells-gtk-devel
