You have a few options - depending on how flexible the communication needs to be ... If the apps just need to send simple notifications with only string data, you can use an NSDistributedNotificationCenter. If the apps need to exchange information with a variety of well defined types, you can set up an NSPasteboard to pass the data. If the apps need to actually send messages to each other and interoperate very closely, you need to use NSConnection (the other two mechanisms are implemented on top of NSConnection and using an intermediary server process ... so direct use of NSConnection is more work to code, but is more powerful and more efficient). _______________________________________________ Help-gnustep mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/help-gnustep
