Hi,
I'm currently trying to use the UKKQueue class to monitor file changes from my PyObjC application.
After some fiddling I got the basics working, but encountered some problems and questions:
* What is the minimal way to include such an ObjC wrapper class with py2app? I am using the setup.py from RestEdit [1] right now, but this looks overly complicated. Also this setup doesn't work when using --alias
It's automatically generated from the Xcode project and is a relatively general solution, so it's not minimal. Works fine with --alias here, you should try it with py2app svn trunk.
* I'm using the notifications provided by NSWorkspace:
NSWorkspace.sharedWorkspace().notificationCenter().addObserver_selector _
name_object_(
self, "documentChanged:",
None,
None)
Is there a way to register an observer which listens to specific objects
only? UKKQueue sends notifications with the filename as object, but as
<type 'objc.pyobjc_unicode'> and simply replacing the last None in the
above method with the filename string didn't work.
Yes you can register a notification that listens for specific objects, but that doesn't mean what you think it does.
* This is more a PyObjC question: Can I use any Python class as a delegate for UKKQueue? Or have these to subclass NSObject or something else?
You probably can use any Python class, but the most well tested solution is to use a NSObject subclass whenever you have code that is going to be called from Objective-C, so I would recommend doing that.
