Text and Ink Input and Display
8-24 Using Text
view’s 'text and 'styles slots are generated and placed in the context frame of
the view.
When SetValue is called with a string parameter that is a rich string, it is
automatically decoded into a text and style pair. The result is stored in the view
frame of the paragraph view.
Rich String Functions 8
You can use the rich string functions to convert and work with rich strings. Each of
these functions, shown in Table 8-7, is described in “Rich String Functions and
Methods” (page 7-31) in Newton Programmer’s Reference.
