The function execute-with-interface
is a useful way of operating on an interface owned by another process. It takes a top-level interface, a function designator function and some arguments args and queues the function to be run by that process when it next enters its event loop (for an interface owned by the current process, it calls the function immediately).
execute-with-interface
applies function even if interface does not have a screen representation, for example when it is destroyed. To call function only if interface has a representation, use execute-with-interface-if-alive.execute-with-interface
is a useful utility in other circumstances.execute-with-interface
calls function on the current process if interface does not have a process.(setq a (capi:display (make-instance 'capi:interface)))
(capi:execute-with-interface a 'break "Break inside the interface process")
