Environment: Symbolics CLIM early release 1.0.
I created a CLIM frame with a Lisp Listener :interactor
pane, where I evaluate a form which runs until I type the
character "q". Mouse sensitive output is drawn on several
frame panes while the form is running. I defined presentation
actions to "pop-up" a window, when the mouse is clicked over
the mouse sensitive output. Only one minor problem -- while
the form is active, the mouse handling appears to be inhibited.
After I type the "q" and the form returns and the :interactor is
waiting for input, the presentation actions work just fine.
Is there a way to have the presentation actions enabled during the
the running of the :interactor pane form? Do I have to create two
CLIM frames and have the :interactor running in one, and the mouse
sensitive output drawn on the second frame where the presentation
actions will be defined?
Have a background process that is waiting for input on the same stream
as the interactor. Be very careful, use locks.
Using background processes and locks isn't portable, is it? I should have
specified that I am looking for a portable CLIM solution.
"[creating] two CLIM frames and have the:interactor running in one, and
the mouse sensitive output drawn on the second" will not work in the
absence of multiple processes, either.
I can think of no portable solution to this in CLIM 1.0.
Thanks for any suggestions.
