Nope. (And not to pull rank, but I was on the AppleEvents/AppleScript team at the time we figured this stuff out [1991] and added the seemingly-useless ‘oapp’ event in response to developer complaints.) Many apps have a different behavior when launched with no docs/URLs (e.g. the app itself is double-clicked). For example, Apple’s iWork apps open a new-document assistant. The only reliable way an app can tell whether it was launched without a doc/URL is if it gets the ‘oapp’ event instead, and the way that event gets sent is when LaunchServices is told to launch the app but not given any other AppleEvent to launch it with. Thus there is a valuable semantic difference between the two cases. > Since a GURL Apple Event (which is what is used to send URLs to applications > in both cases) can occur at any time, and your app may be already running or > may need to be launched to be possible to send an Apple Event to it, you can > never rely on a particular order. Sure, an app has to be prepared to receive ‘odoc' or ‘GURL’ events while running. But that’s a different case from at launch, as I explained. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
