PopupBindings

=============

"PopupBindings" is a Cocoa sample application that demonstrates how to use the bindings to manage the contents and selection of the NSPopupButton class.  It uses the NSArrayController class to hold the data and track the selection.

This is done using the following NSPopupButton bindings:

The content binding describes the collection of objects. The collection is the objects in the array controller.

    Bind to: PopupList

    Controller Key: arrangedObjects

    Model Key Path: (leave blank)

The contentValues binding describes what will be displayed in the pop-up menu. In this example it will be "name" portion of the Person object. Use the following choices for the contentValues binding:

    Bind to: PopupList

    Controller Key: arrangedObjects

    Model Key Path: name

The selectedIndex binding describes the indexed selection the user chose from the menu. Use the following choices for the selectedIndex binding:

    Bind to: PopupList

    Controller Key: selectionIndex

    Model Key Path: (leave blank)

All four NSTextFields describing the person's address is bound to the array controller's selection using a specific NSDictionary key.  So for the "street" NSTextField, its value binding should look like:

    Bind to: PopupList

    Controller Key: selection

    Model Key Path: addressStreet
