The directory Scripts contains a number of simple command-line scripts that make use of Cocoa features.
This script is a daemon that will open the ReadMe file in the root of any (removable) volume that is inserted while this script is running.
The script is part of Introduction to PyObjC, an article at O'Reilly MacDevCenter.com.
This script shows how to use PyObjCTools.Debugging to show tracebacks of all (Cocoa) exceptions (handled and unhandled).
Demonstrate the usage of an NSMutableDictionary object with both Objective-C and Python dictionary syntax.
An example of using the AddressBook framework, this script exports some of the information about people in your addressbook to a CSV file.
Demonstrate the usage of objc.loadBundleFunctions to access functionality from the standard C library on Mac OS X (libSystem, which is also available as the System.framework bundle). This example uses the dyld runtime to determine which dylib the Python runtime came from.
Demonstrates a nib-less Cocoa GUI (purely for informational purposes, you probably shouldn't make a habit of this)
XXX An example script that demonstrates how PyObjC interacts with Key-Value Observing (KVO) at the lowest level. This script was used to debug the PyObjC runtime and should not be used as a guideline for writing new KVO code. It may be interesting to some until we ensure that we have proper unit tests for KVO and remove this example!
Shows how PyObjCTools.Conversion can be used to convert a Python collection into an Objective-C property list. These functions should not typically be necessary as the proxies for Python objects are compatible with Objective-C plists.
Use an NSNetService class to look for servers using rendezvous.
Demonstrates how to get a backtrace when handling a fatal signal using PyObjCTools.Signals.
Demonstrates how to write a console runloop based application that uses NSFileHandle to read stdin asynchronously.
A doctest that demonstrates the subclassing of an Objective-C class from Python. Note that it is typically discouraged to define a __del__ method.
Demonstrates how create a subclass of an Objective-C class that overrides a selector, but calls the super implementation using Python syntax equivalent to [super init].
Another objc.loadBundleFunctions demonstration that shows how to call into a private CoreGraphics SPI and enable full WindowManager access from a process that would not otherwise have it due to a quirk in the implementation of WindowManager (the reason why pythonw should be used instead of python). Use at your own risk!
The directory AppKit contains example applications using the Cocoa Application Framework (aka "AppKit").
Most of the following examples contain a setup.py script that can build an application. See Building applications for details how to invoke these scripts. Some examples contain an Xcode or Project Builder project file; simply double-click it and choose Build and Run, or invoke xcodebuild or pbxbuild from the command line depending on which you have installed.

The CocoaBindings directory contains a number of examples that make use of Key-Value Coding and Cocoa Bindings. These scripts require Mac OS X 10.3 or later.
Shows custom array controller that implements table view data source methods to support drag and drop, including copying objects from one window to another, drop of URLs, and re-ordering of the content array.
Originally from Cocoa Bindings Examples and Hints, converted to PyObjC by u.fiedler.
Demonstrates how to use Cocoa Bindings to simplify storing and retrieving user preferences. Also demonstrates how to use an NSValueTransformer to archive/unarchive a non-property-list type automatically (NSColor, in this case).
Originally from Cocoa Bindings Examples and Hints, converted to PyObjC by u.fiedler.
A rewrite of CurrencyConverter using Cocoa Bindings.
Originally from Introduction to Developing Cocoa Applications Using Bindings, converted to PyObjC by u.fiedler.
Demonstrates how to subclass NSArrayController to implement filtering of a NSTableView. Also demonstrates the use of indexed accessors.
Originally from Cocoa Bindings Examples and Hints, converted to PyObjC by u.fiedler.
Shows the use of a custom controller, a value transformer, and two custom bindings-enabled views. One view is a control that allows you to set the angle and offset of a shadow; the other view observes and displays a collection of graphic objects.
Originally from Cocoa Bindings Examples and Hints, converted to PyObjC by u.fiedler.
A simple example that illustrates establishing bindings programmatically, including a number of options such as validation and an array operator, and indexed accessor methods. A custom model object implements custom validation method.

Demonstrates how to write an application that detects the launch of another application by bundle identifier, how to use objc.inject to load code into another application, how to override the implementation of an existing class but still call back into the original implementation, and how to reduce the size of such an application/plugin combination by using symlinks to share object files (the PyObjC extensions in this case).
