+    The CPFont class allows control of the fonts used for displaying text anywhere on the screen.
+    The primary method for getting a particular font is through one of the class methods that take
+    a name and/or size as arguments, and return the appropriate CPFont.
+
+    By default the system font face/size is Arial 12px, with a fallback to sans-serif. You may
+    configure this at runtime in two ways:
+
+    - By sending [CPFont @link CPFont::setSystemFontFace: setSystemFontFace:@endlink] and/or [CPFont @link CPFont::setSystemFontSize: setSystemFontSize:@endlink].
+    - By configuring Info.plist for your application or for AppKit. You can set the font face
+      by adding a CPSystemFontFace string item to the Info.plist, and you can set the font size
+      by adding a CPSystemFontSize integer item to the Info.plist.
+
+    Note that in either case, you can specify a comma-delimited list of fonts as the font face.
+    The browser will use the first available font in the list. CPFont always ensures that Arial
+    and sans-serif are in the generated CSS string, so there is no need to add them to the end
+    of your font list.
+
+    If you are using nib2cib, you should use the second method (using Info.plist),
+    and be sure to run nib2cib again any time you modify the CPSystemFontFace or CPSystemFontSize items.
+    For example, you might add this to your application's Info.plist to set the system font to Lucida Grande,
+    with an automatic fallback to Arial or sans-serif:
+
+    @code
+<key>CPSystemFontFace</key>
+<string>Lucida Grande</string>
+	@endcode

+
+    @brief CPPredicateEditor is a subclass of CPRuleEditor that is specialized for editing CPPredicate objects.
+
+    CPPredicateEditor provides a CPPredicate property—objectValue (inherited from CPControl)—that you can get and set directly, and that you can bind using bindings (you typically configure a predicate editor in Interface Builder). CPPredicateEditor depends on another class, CPPredicateEditorRowTemplate, that describes the available predicates and how to display them.
+
+    Unlike CPRuleEditor, CPPredicateEditor does not depend on its delegate to populate its rows (and does not call the populating delegate methods). Instead, its rows are populated from its objectValue property (an instance of CPPredicate). CPPredicateEditor relies on instances CPPredicateEditorRowTemplate, which are responsible for mapping back and forth between the displayed view values and various predicates.
+
+    CPPredicateEditor exposes one property, rowTemplates, which is an array of CPPredicateEditorRowTemplate objects.

+    @ingroup appkit
+    @class CPPredicateEditorRowTemplate
+
+    @brief CPPredicateEditorRowTemplate describes available predicates and how to display them.
+
+    You can create instances of CPPredicateEditorRowTemplate programmatically or in Interface Builder. By default, a non-compound row template has three views: a popup (or static text field) on the left, a popup or static text field for operators, and either a popup or other view on the right.  You can subclass CPPredicateEditorRowTemplate to create a row template with different numbers or types of views.
+
+    CPPredicateEditorRowTemplate is a concrete class, but it has five primitive methods which are called by CPPredicateEditor: -#templateViews, -#matchForPredicate:, -#setPredicate:, -#displayableSubpredicatesOfPredicate:, and -#predicateWithSubpredicates:. CPPredicateEditorRowTemplate implements all of them, but you can override them for custom templates. The primitive methods are used by an instance of CPPredicateEditor as follows.
+
+    First, an instance of CPPredicateEditor is created, and some row templates are set on it—either through a nib file or programmatically. The first thing predicate editor does is ask each of the templates for their views, using templateViews.
+
+    After setting up the predicate editor, you typically send it a  CPPredicateEditor#setObjectValue: message to restore a saved predicate. CPPredicateEditor needs to determine which of its templates should display each predicate in the predicate tree. It does this by sending each of its row templates a matchForPredicate: message and choosing the one that returns the highest value.
+
+    After finding the best match for a predicate, CPPredicateEditor copies that template to get fresh views, inserts them into the proper row, and then sets the predicate on the template using setPredicate:. Within that method, the CPPredicateEditorRowTemplate object must set its views' values to represent that predicate.
+
+    CPPredicateEditorRowTemplate next asks the template for the “displayable sub-predicates” of the predicate by sending a -#displayableSubpredicatesOfPredicate: message. If a template represents a predicate in its entirety, or if the predicate has no subpredicates, it can return nil for this.  Otherwise, it should return a list of predicates to be made into sub-rows of that template's row. The whole process repeats for each sub-predicate.
+
+    At this point, the user sees the predicate that was saved.  If the user then makes some changes to the views of the templates, this causes CPPredicateEditor to recompute its predicate by asking each of the templates to return the predicate represented by the new view values, passing in the subpredicates represented by the sub-rows (an empty array if there are none, or nil if they aren't supported by that predicate type).

     This method sets the "prototype" view which will be used to create all table cells in this column.
 
     It creates a snapshot of aView, using keyed archiving, which is then copied over and over for each
     individual cell that is shown. As a result, changes made after calling this method won't be reflected.
 
-    When you set a dataview and it is added to the tableview the theme state will be set to CPThemeStateTableDataView

-
-    You should overide setThemeState: and unsetThemeState: to handle these theme state changes in your dataview.

-

+    [[tableColumn dataView] setSomething:x]; //won't work
