This application demonstrates interrogating the layout manager for information about text layout, and the use of temporary attributes to color text. Specifically, we provide rollover coloring of text--one color for the line, another for the word, and a third for the character under the mouse. A subclass of NSTextView is used, but solely for the purpose of obtaining mouse events. The interesting portion of the code involves the conversion of mouse coordinates to a particular glyph and character index, then determining the corresponding line and word, and finally using temporary attributes for coloring.
