Re: Messaging across threads using NSThread

[Riccardo Mottola]

Hello,

in FTP (available in GAP, http://gap.nongnu.org) I do inter-thread 
messaging with the precise goal to have threads perform operations on 
the main thread GUI operations.

I set up DO between the app itself this way:
   // we set up distributed objects
   port1 = [NSPort port];
   port2 = [NSPort port];
   kitConnection = [[NSConnection alloc] initWithReceivePort:port1
                                                    sendPort:port2];
   [kitConnection setRootObject:self];
  
   /* Ports switched here. */
   portArray = [NSArray arrayWithObjects:port2, port1, nil];
   [NSThread detachNewThreadSelector: @selector(connectWithPorts:)
                            toTarget: [FtpClient class]
                          withObject: portArray];


inside "connectWithPorts" I do:

   serverConnection = [NSConnection
           connectionWithReceivePort:[portArray objectAtIndex:0]
                            sendPort:[portArray objectAtIndex:1]];
  
   serverObject = [self alloc];
   [(id)[serverConnection rootProxy] setServer:serverObject];
   [serverObject release];
  
   [[NSRunLoop currentRunLoop] run];


at this point DO is set up,

when the FtpClient class calls the controller, it will invoke its 
methods on the main thread.

It works for me both on Unix as on Windows.
