Thx Terry, that might be an idea .. the calculations are not that diff so i could rewrite them in Obj-C to keep the task object small … or the other way around: i'll create a task with a panel and pipe the cancel to the process Rob Could you wrap the process into an NSTask and use pipes to communicate?

A key event seems to wait until the app gets back to the main loop, a system("stty raw -echo") just hangs, gets and read.non-block either wait or want a enter to follow any character. I couldn't get it working with a notification either. I just can't find it :) .. Any help appreciated .. tnx, Rob _______________________________________________ MacRuby-devel mailing list MacRuby-devel at lists.macosforge.org http://lists.macosforge.org/mailman/listinfo.cgi/macruby-devel • Previous message: [MacRuby-devel] Noob q: Press any key to cancel • Next message: [MacRuby-devel] #welovemacruby • Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] More information about the MacRuby-devel mailing list
