FieldView | Extends the multi-line plain text view to be suitable for a single-line editor view.
FlowView | A View that tries to flow it's children into some partially constrained space.
FlowView.FlowStrategy | Strategy for maintaining the physical form of the flow.

TabSet | A TabSet is comprised of many TabStops.
TabStop | This class encapsulates a single tab stop (basically as tab stops are thought of by RTF).

## Package javax.swing.text Description

Provides classes and interfaces that deal with editable and noneditable text components. Examples of text components are text fields and text areas, of which password fields and document editors are special instantiations. Features that are supported by this package include selection/highlighting, editing, style, and key mapping.

Note: Most of the Swing API is not thread safe. For details, see Threads and Swing, a section in The Java Tutorial.
