This is the base class for all template field types. Subclass this to
|
|
define a field type of your own.
|
|
|
|
Note that subclasses *must* implement the NSCopying protocol, which means
|
|
if you have instance variables, you must provide your own copyWithZone:
|
|
implementation that calls through to the superclass and then copies its
|
|
own variables' values (or retains references to them, if that is more
|
|
effective and the object in question isn't mutable).

the template editor will forward any calls to these items to the element, if it

implements them, and it will automatically enable the appropriate menu items. It

will also forward validateMenuItem:for the Paste menu item to the element.

The createListEntry:action will also be forwarded to elements by the

template editor. Use this to allow creating new list items or for similar

purposes ("Create New Resource..." is renamed to "Create List Entry" while the

template editor is key). */
