"TextLayoutDemo" is a Cocoa sample application that demonstrates how to customize NSTextView with NSLayoutManager and by subclassing NSTextContainer. This is structured as a demo for use in the session "Customizing the Cocoa Text System (134)" for WWDC 2007.
The supplied Xcode project was created using Xcode v4.3 running under Mac OS X 10.7.x or later.
Using the Sample
Simply build and run the sample using Xcode. The following Command-keys demonstrate -
Cmd<1> = An unmodified NSTextView.
Cmd<2> = Multiple instances of NSLayoutManager to provide for two-column text layout.
Cmd<3> = A subclass of NSTextContainer to provide for round layout.
Cmd<4> = Glyphs are incrementally laid out around a circular path.
