Description
Name: nl37777			Date: 02/27/2002

The JTextComponent implementation currently creates break
iterators on the fly, and always uses a natural language break iterator
obtained from BreakIterator.get*Instance methods. This makes it hard to
use JTextComponent to implement a program editor, where word breaks
should correspond to programming language tokens. There should be an API
that lets a client program set the BreakIterator to be used for all
breaking operations in the JTextComponent.

See the related RFE 4644224.

Comments
EVALUATION Line breaking rules are specific to the model; AbstractDocument seems to be a suitable place for setting BreakIterator for a Document. GlyphView should check for existence of explicit BreakIterator for a Document before creating its own.
