Module java.desktop
Package javax.swing.text
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 Concurrency in Swing , a section in The Java Tutorial .

Interface Summary Interface Description AbstractDocument.AttributeContext An interface that can be used to allow MutableAttributeSet implementations to use pluggable attribute compression techniques.AbstractDocument.Content Interface to describe a sequence of character content that can be edited.AttributeSet A collection of unique attributes.AttributeSet.CharacterAttribute This interface is the type signature that is expected to be present on any attribute key that contributes to character level presentation.AttributeSet.ColorAttribute This interface is the type signature that is expected to be present on any attribute key that contributes to presentation of color.AttributeSet.FontAttribute This interface is the type signature that is expected to be present on any attribute key that contributes to the determination of what font to use to render some text.AttributeSet.ParagraphAttribute This interface is the type signature that is expected to be present on any attribute key that contributes to the paragraph level presentation.Caret A place within a document view that represents where things can be inserted into the document model.Document TheDocument
