How can I gain access from my program to files dragged on the application icon?

[Apocalypse]

Someone recently helped me out with this one so here is what I have learned from playing with this:

First you have to edit the active target of your program to allow it to read documents with the extensions you want ("*" for all, "fold" if you want folders, as well).

Then you have to implement the "openFile" method in your application's delegate:
"- (BOOL)application NSApplication *)theApplication openFile NSString *)filename"

This method will be called once for every file that is dropped on the icon. If you drop onto it while it is not open, this method will be called before the "applicationdidFinishLaunching" method (just a FYI).

Hope that helps,
Jeff.

Thanks a bunch. You undoubtedly saved me a lot of time reading through horrible documentation.

If you're using an NSDocumentController, and the above method is *not* implemented in the app delegate, then -openDocumentWithContentsOfFile: will automatically be called on the NSDocumentController instance, which in turn will open up a document automatically if appropriate, etc.

But if you want to do something outside of opening up documents with files that are dropped on your app icon, then that app delegate method is the one to use.
