I have a hard time seeing the need for this class.
+ case AS_TALK_TO_DESKTOP_LISTENER:
+ {
+ port_id senderPort;
+ link.Read<port_id>(&senderPort);
+ BPrivate::LinkSender sender(senderPort);
+ BPrivate::PortLinkRef listenerLink(&sender, &link);
+ if (fDesktop->MessageForListener(fWindow, listenerLink))
+ break;
+ // unhandled message at least send an error if needed
+ if (link.NeedsReply()) {
+ sender.StartMessage(B_ERROR);
+ sender.Flush();
+ }
+ break;
+ }
Why so complicated? Ie. why is the communication not using the standard
window return path?
Bye,
Axel.
