Thanks, Ken. I stumbled onto the solution by way of an old page about how to drag text snippets onto the dock icon in an PyObjC app. Who knows how long I'd have been scratching my head if I hadn't guessed the same approach might work for URLs.
For a minute it looked like I could use the same code to handle files dragged to the dock icon from the Finder. My service did get invoked, and it was passed an NSPasteboard that was superficially similar in that it contained URLs, in this case file URLs rather than web URLs. But when I tried to iterate through the file URLs I got messages like this: 2013-12-22 14:43:32.732 DockHow[34606:303] Failed to get a sandbox extensions for itemIdentifier (1). The data for the sandbox extension was NULL I didn't feel like messing with sandbox stuff, so I implemented application:openFiles: in addition to the service. And now I don't remember if that worked, because I decided I didn't really need to accept dragged URLs after all! But still, good to know for future reference. --Andy On Dec 21, 2013, at 7:48 PM, Ken Thomases <k...@codeweavers.com> wrote: > For what it's worth, this is documented somewhat in Cocoa Scripting Guide: > How Cocoa Applications Handle Apple Events – Apple Events Sent by the Mac OS > – Open Contents. > https://developer.apple.com/library/mac/documentation/cocoa/conceptual/ScriptableCocoaApplications/SApps_handle_AEs/SAppsHandleAEs.html#//apple_ref/doc/uid/20001239-1121328 > > Cheers, > Ken > > On Dec 21, 2013, at 5:22 PM, Andy Lee wrote: > >> To answer my own question, it looks like it's done by implementing a >> Service.
