The NSDistributedNotificationCenter class provides a way to send
notifications to objects in other tasks.

Hi,
We have an application that needs to launch another application
from within itself. Now, we could either do this using NSTask's
"launchedTaskWithLaunchPath:arguments:" or getting the shared
workspace from NSWorkspace and send "launchApplication:" to it.
Now the problem is that we want the newly launched application to
(1) get focus (e.g. we want it to be the active application from
now on) and (2) to be able to receive the regular command line
arguments we send it. The two above mentioned operations either
accomplishes 1 (NSWorkspace) or 2 (NSTask) but not both
simultaneously.
Does anyone know how I could solve this?
Thanks in advance, and merry christmas.
Mattias
I don't know a proper Cocoa way to do it but i can give you a
workaround.
NSTask *task = [NSTask ......];
pid_t pid = [task processIdentifier];
ProcessSerialNumber psn;
if (noErr == GetProcessForPID(pid, &psn)) {
SetFrontProcess(&psn);
}
The LSOpenApplication() function may also works, but the doc says
that argv is ignored on 10.4, so use it only if you want to target
Leopard.
Merry christmas too
