Cocoa in a Nutshell

Name

NSRulerView — Mac OS X 10.0

Synopsis

This is a subclass of NSView and is used to draw rulers in an NSScrollView. A ruler view keeps track of the units used to convert measurements between pixels and whatever unit the client specifies should be displayed by the ruler view. A ruler view may contain ruler markers, which are instances of the class NSRulerMarker.
