When I install a custom URL handler like this:
NSAppleEventManager *aem = [NSAppleEventManager sharedAppleEventManager] ;
[aem setEventHandler:self
andSelector:@selector(handleGetURLEvent:withReplyEvent:)
forEventClass:kInternetEventClass
andEventID:kAEGetURL] ;
even if I change my handler to no-op like this,
- (void)handleGetURLEvent:(NSAppleEventDescriptor*)event
withReplyEvent:(NSAppleEventDescriptor*)replyEvent {
return ;
...
}
still when such custom URL is received, the system still brings all of the
app's windows to the front. I want the app to receive the message silently and
then I'll display a window if needed.
I was wondering if anyone knows any way to change the activation behavior.
I've set breakpoints on -[NSApplication activateIgoringOtherApps:] and also
NSWindow methods one would use to front or display a window, but they never
break. It's like Apple is using some master 'activate' switch under the hood.
Yes, I know how to fix this by using a less cheesy method of interapplication
communication, but I'm trying to be lazy. Another alternative is to
re-activate the prior frontmost app, or hide the app, after it activates, but
that looks pretty bad. To truly restore the user's workspace I'd need an API
which gives the ordering of windows on the screen relative to those of other
apps, but I've never been able to find such API.
Thanks,
Jerry Krinock
