The javax.swing.text Package (Java Foundation Classes)

This large and complex package contains the powerful JTextComponent text editor and all of its supporting infrastructure. The JTextField, JTextArea, JEditorPane, and other text input components of the javax.swing package all subclass JTextComponent and rely on the other classes and interfaces of this package.

The Document interface defines the data model for the JTextComponent. It is the basic abstraction for documents that can be displayed and edited. The AbstractDocument class implements this interface and provides a number of useful features and extensions. StyledDocument extends Document to define support for documents that have styles associated with their content. DefaultStyledDocument is a concrete implementation based on AbstractDocument. Other important classes and interfaces in this package include: EditorKit, Element, View, AbstractDocument.Content, Caret, and Highlighter. Figure 30-1 shows the class hierarchy of this package.

AbstractDocument

Java 1.2

javax.swing.text

serializable

This class is a partial, abstract implementation of the Document interface, which also defines several important inner classes and interfaces. Typical applications do not have to use or subclass this class. Instead, they can rely on predefined concrete implementations such as PlainDocument, DefaultStyledDocument, and javax.swing.text.html.HTMLDocument.

AbstractDocument.AbstractElement

Java 1.2

javax.swing.text

serializable

This abstract class is a partial implementation of the Element interface. Document objects derived from AbstractDocument are composed of Element objects derived from AbstractDocument.AbstractElement. In addition to implementing Element, this class also implements the MutableAttributeSet interface, so it can serve as its own attribute set. And it implements the TreeNode interface, which can make it easy to display the element structure of an AbstractDocument using the JTree component (a useful debugging technique). Applications typically do not use or subclass this class. See also the BranchElement and LeafElement subclasses, both of which are also inner classes of AbstractDocument.

AbstractDocument.AttributeContext

Java 1.2

javax.swing.text

This interface defines methods that accept an immutable AttributeSet argument and return another immutable AttributeSet object. These methods can be used to implement the MutableAttributeSet interface entirely in terms of immutable AttributeSet objects. Most documents frequently reuse a small set of common attribute sets. The use of immutable AttributeSet objects is desirable because they may be cached and shared, resulting in substantial memory savings. JTextComponent uses the attribute set caching technique by default, and typical applications never need to use or implement this interface. See StyleContext for a concrete implementation of this interface.

public abstract static interface AbstractDocument.AttributeContext {
//	Public Instance Methods
	public abstract AttributeSet addAttribute (AttributeSet old, Object name, Object value);
	public abstract AttributeSet addAttributes (AttributeSet old, AttributeSet attr);
	public abstract AttributeSet getEmptySet ();

AbstractDocument.Content

Java 1.2

javax.swing.text

This interface defines an abstract representation of an editable piece of text. An AbstractDocument.Content object is used to represent the contents of any Document derived from AbstractDocument. A Content implementation must be able to return arbitrary text segments, insert and delete text, and return Position objects that mark positions within the content. If the Content implementation allows undo operations, the insertString() method should return an UndoableEdit object; otherwise it should return null. Applications typically do not use or implement this interface. See StringContent and GapContent for two implementations.

public abstract static interface AbstractDocument.Content {
//	Public Instance Methods
	public abstract Position createPosition (int offset) throws BadLocationException;
	public abstract void getChars (int where, int len, Segment txt) throws BadLocationException;

AbstractWriter

Java 1.2

javax.swing.text

This abstract class provides a simple but convenient starting place for applications that want to write a textual representation of a Document or Element tree. The abstract write() method must be implemented by a subclass. This method must iterate over the Document or Element tree (using the ElementIterator provided by getElementIterator()) and write out a textual description of the Element objects using the other methods of the class. Applications do not typically use or subclass this class.

AttributeSet

Java 1.2

javax.swing.text

This interface defines the basic methods required for a set of attributes. It defines a mapping from attribute names, or keys, to attribute values. Both keys and values can be arbitrary objects. The StyleConstants class defines a number of commonly used attribute keys. The AttributeSet interface defines four inner interfaces. These empty interfaces serve as marker interfaces and should be implemented by an attribute key object to specify the general category of the key.

An AttributeSet can have another AttributeSet as its parent. When you look up a value with getAttribute(), the local mappings are searched first. If no matching attribute is found locally, however, the search continues (recursively) on the parent AttributeSet. The parent attribute set is itself stored as an attribute, using the key defined by the ResolveAttribute constant. Call getResolveParent() to query the parent AttributeSet. The isDefined() and getAttributeNames() methods operate only on the local attribute mappings and do not use the parent AttributeSet.

See also MutableAttributeSet, SimpleAttributeSet, Style, and StyleConstants.

Caret

Java 1.2

javax.swing.text

This interface defines the methods that must be implemented by a class that wants to keep track of the insertion cursor position and draw the insertion cursor for a JTextComponent. In the nomenclature of text editing, the dot is the current insertion position, and the mark is some other position in the text. The text between the dot and the mark is implicitly selected, and certain editing commands operate on this text. The setDot() method sets the position of both the dot and the mark, while moveDot() sets the position of the dot, leaving the mark where it is. The paint() method is called when the insertion cursor needs to be drawn or redrawn. setBlinkRate() specifies how often the cursor should blink. If the cursor does blink, Caret is responsible for causing this blinking; paint() is not automatically called to implement blinking. The Caret should notify any registered ChangeListener objects when the position of the cursor changes.

Although the Caret interface allows the appearance and behavior of the JTextComponent cursor to be customized, it is uncommon to do this. Most applications are perfectly content to use DefaultCaret, which is the Caret implementation installed by all the standard look-and-feels.

DefaultStyledDocument.ElementBuffer

Java 1.2

javax.swing.text

serializable

This class allows insertions into an Element tree in the form of an array of DefaultStyledDocument.ElementSpec objects. This is useful because a linear array of ElementSpec objects is often easier to work with than a tree of Element objects.

public class DefaultStyledDocument.ElementBuffer implements Serializable {

DefaultStyledDocument.ElementSpec

Java 1.2

javax.swing.text

This class is used to represent the elements of a document in a flat structure, instead of a tree. An ElementSpec object represent a start tag, an end tag, or document content. Arrays of ElementSpec objects can be used to represent a document or a portion of a document, and these ElementSpec objects can later be converted into a tree of Element objects. This class can be useful because it is often easier to work with an array of ElementSpec objects than with a tree of Element objects.

public static class DefaultStyledDocument.ElementSpec {
//	Public Constructors
	public ElementSpec (AttributeSet a, short type);
	public ElementSpec (AttributeSet a, short type, int len);

Document

Java 1.2

javax.swing.text

This interface defines the fundamental methods required in a class that stores document text to be displayed and edited by a JTextComponent. The methods of this interface require that a Document object be able to represent document content both as a linear sequence of characters and as a tree of hierarchical Element objects. Element objects model the document structure and are used to represent things like paragraphs, lines, and runs of styled text. When a JTree component displays a Document, the Element tree is used to create a tree of View objects that display the individual elements.

The getText() methods return text from the document, either as a String or in a supplied Segment object. insertString() inserts a run of text associated with the specified attributes. remove() deletes text from the Document. The Document object must fire appropriate DocumentEvent and UndoableEditEvent events when edits like these are performed. createPosition() returns a Position object that represents a relative position in the document. The Position reference remains valid even if text is inserted or deleted from the document. The putProperty() and getProperty() methods allow arbitrary key/value pairs to be associated with a Document. These properties can be used to hold metainformation, such as the author and title of the document. The TitleProperty and StreamDescriptionProperty constants are two predefined property keys. Finally, the render() method must run the specified Runnable object while guaranteeing that there will not be any changes to the document. This method is used to perform the potentially time-consuming document-rendering process in a thread-safe way.

EditorKit

Java 1.2

javax.swing.text

cloneable serializable

This abstract class defines the methods that are used to configure a JEditorPane to display and edit a particular type of document. Swing contains concrete subclasses for plain text, as well as HTML and RTF documents. To configure a JEditorPane, instantiate an EditorKit object and pass it to the setEditorKit() method of your JEditorPane.

The getContentType() method of an EditorKit returns the MIME type supported by the kit. createDefaultDocument() creates an appropriate type of empty Document object to hold the document. The read() and write() methods read and write document content from and to streams. getViewFactory() returns a ViewFactory object for this document type. The ViewFactory is used to convert the Element objects of the document into View objects that display the document on the screen. createCaret() returns a Caret object that the JEditorPane can use to navigate the document, and getActions() returns an array of Action objects that the JEditorPane can bind to keystrokes. EditorKit implementations typically define a number of Action implementations as inner classes.

Element

Java 1.2

javax.swing.text

This interface defines the methods required for objects that want to be part of a Document object's element tree. An Element object must keep track of its parent and its children. It must also know its position and the position of its children within the linear sequence of characters that comprise the Document. Finally, an Element must be able to return the set of attributes that have been applied to it. getParentElement() returns the parent. getElementCount() and getElement() return the number of child elements and the specified child element, respectively. getStartOffset() and getEndOffset() return the start and end positions of this element. getElementIndex() returns the index of the child element that contains the specified position. getAttributes() returns the AttributeSet for this element.

GapContent

Java 1.2

javax.swing.text

serializable

This class is an implementation of the AbstractDocument.Content interface that uses an array of characters with a gap of unused characters in it. This gap is positioned near the current insertion position so that subsequent insertions require fewer characters to be shifted in the array. This implementation is more complicated than StringContent, but it works efficiently with documents of any size. This is the default Content implementation for all documents derived from AbstractDocument. This class inherits from a private superclass, GapVector, which is not covered in this book because it is private.

public class GapContent extends GapVector implements AbstractDocument.Content, Serializable {
//	Public Constructors
	public GapContent ();
	public GapContent (int initialLength);

Highlighter

Java 1.2

javax.swing.text

This interface defines the methods that must be implemented by an object that wants to maintain and draw the list of selected regions within a JTextComponent. The methods of Highlighter allow selected regions to be added, changed, and removed for the set of highlighted regions. Each region is specified as a start and end position within the Document and a Highlighter.HighlightPainter object that is used to draw the highlight. The getHighlights() method returns an array of Highlighter.Highlight objects that describe the individual highlighted regions and their painter objects. Most applications can rely on the DefaultHighlighter class that is used by default by JTextComponent and never have to implement this interface.

public abstract interface Highlighter {
//	Inner Classes
	;
	;
//	Public Instance Methods
	public abstract Object addHighlight (int p0, int p1, Highlighter.HighlightPainter p) throws BadLocationException;
	public abstract void changeHighlight (Object tag, int p0, int p1) throws BadLocationException;

JTextComponent

Java 1.2

javax.swing.text

serializable accessible(text) swing component

This is the base class for all Swing text-editing components. Applications do not use this class directly, but instead use one of its subclasses in the javax.swing package: JTextField, JTextArea, JPasswordField, JEditorPane, or JTextPane. A JTextComponent displays the text contained in its model object, an object of type Document. Other important classes and interfaces used by JTextComponent are Caret, Highlighter, Keymap, Style, EditorKit, TextAction, and View.

JTextComponent.KeyBinding

Java 1.2

javax.swing.text

This class encapsulates a KeyStroke and the name of an Action object. The JTextComponent.KeyBinding class is used primarily for communication between the JTextComponent and its UI delegate object.

public static class JTextComponent.KeyBinding {
//	Public Constructors
	public KeyBinding (KeyStroke key, String actionName);
//	Public Instance Fields
	public String actionName ;

Keymap

Java 1.2

javax.swing.text

This interface defines the methods of an object that can map javax.swing.KeyStroke objects to javax.swing.Action objects. A Keymap object is used to maintain the set of key bindings for a JTextComponent. Key-to-action bindings are added to a Keymap with addActionForKeyStroke(). The action bound to a given keystroke is queried with getAction(). Every Keymap can refer to another Keymap as its parent. If getAction() cannot find a specified KeyStroke mapping locally, it searches (recursively) in the parent Keymap.

There are no public implementations of the Keymap interface, so you cannot create a Keymap simply by calling a constructor. JTextComponent relies on a private implementation of Keymap, however, and you can obtain an instance by calling the static addKeymap() method of that class. Once you have initialized this Keymap with any desired bindings, you can pass it to the setKeymap() method of any JTextComponent instance.

public abstract interface Keymap {
//	Property Accessor Methods (by property name)
	public abstract Action[ ] getBoundActions ();
	public abstract KeyStroke[ ] getBoundKeyStrokes ();

LabelView

Java 1.2

javax.swing.text

This View class displays a run of text that has a single set of character attributes, such as colors and fonts, associated with it. It supports line breaking and tab expansion.

public class LabelView extends View {

LayeredHighlighter

Java 1.2

javax.swing.text

This abstract class is a Highlighter. Instead of implementing the abstract methods of the Highlighter interface, however, it adds another abstract method of its own. This new method, paintLayeredHighlights(), is called to draw a portion of the highlight that appears within the region defined by a single View object. Typical applications can rely on the DefaultHighlighter class that is automatically used by JTextComponent and never have to use or implement this class.

public abstract class LayeredHighlighter implements Highlighter {
//	Public Constructors

ParagraphView

Java 1.2

javax.swing.text

This BoxView subclass displays a column of subviews, one for each row or line in the paragraph. These rows are implemented by a private internal BoxView class. ParagraphView handles word wrapping by breaking its views as necessary to fit them into the row views it creates. ParagraphView supports various paragraph-level attributes such as margins, line spacing, and first-line indent.

PlainDocument

Java 1.2

javax.swing.text

serializable

This concrete AbstractDocument subclass defines a plain-text document with no character attributes. The root element of the document has one child element for each line in the document. By default, PlainDocument uses a GapContent object to hold its textual content. Applications rarely need to work with a PlainDocument class directly. Typically, they can simply use the JTextArea or JTextField components for displaying and editing text.

Position

Java 1.2

javax.swing.text

This interface describes a position within a Document in a way that is insensitive to insertions and deletions within the document. The getOffset() method returns the character offset of that position. For editable documents, a Position object must keep track of edits and adjust the character offset as necessary.

public abstract interface Position {
//	Inner Classes
	;
//	Public Instance Methods
	public abstract int getOffset ();
}

Position.Bias

Java 1.2

javax.swing.text

The Document interface describes positions within the document using integer offsets. These numbers refer not to the actual characters of the document, but to the spaces between the characters. This means that, in some cases, a simple integer position might refer to either the character before it or the character after it. In ambiguous cases, therefore, the position must be augmented with a bias value. This inner class defines the two legal bias values: Position.Bias.Backward and Position.Bias.Forward. A number of methods in the javax.swing.text package require one or the other of these constants as an argument.

public static final class Position.Bias {
//	No Constructor
//	Public Constants
	public static final Position.Bias Backward ;
	public static final Position.Bias Forward ;
//	Public Methods Overriding Object
	public String toString ();
}

Type Of: Position.Bias.{Backward, Forward}

Segment

Java 1.2

javax.swing.text

The Segment class represents a segment of text through three public fields. These are a reference to a character array, the array offset of the first character in the array, and the number of characters in the segment. This is an efficient way to pass references to text segments, since it does not require new String objects to be created. However, it is dangerous because it exposes the character array directly and makes it vulnerable to changes. Users of a Segment object must treat the text segment as if it were immutable, using it for read-only access to the text.

public class Segment {
//	Public Constructors
	public Segment ();
	public Segment (char[ ] array, int offset, int count);
//	Public Methods Overriding Object
	public String toString ();
//	Public Instance Fields
	public char[ ] array ;

SimpleAttributeSet

Java 1.2

javax.swing.text

cloneable serializable

This class is a simple implementation of the MutableAttributeSet interface that uses an internal hashtable. See AttributeSet and MutableAttributeSet for details. When working with many attribute sets, it may be more efficient to define styles using a StyleContext object.

StringContent

Java 1.2

javax.swing.text

serializable

This class is a simple implementation of the AbstractDocument.Content interface based on simple String manipulation. It is suitable only for short documents. By default, all documents derived from AbstractDocument use the GapContent implementation instead of StringContent.

public final class StringContent implements AbstractDocument.Content, Serializable {
//	Public Constructors

Style

Java 1.2

javax.swing.text

This interface extends MutableAttributeSet by adding both a convenience method for retrieving the name of the attribute set and ChangeListener registration methods. A Style object is typically used to represent a named set of attributes. The style name is usually stored as an attribute. Because a Style is a kind of MutableAttributeSet, objects that use the style may want to know when the attributes of the Style change. Interested listeners can register with the addChangeListener() method. They are notified with a ChangeEvent when attributes are added to or removed from the Style.

public abstract interface Style extends MutableAttributeSet {
//	Event Registration Methods (by event name)
	public abstract void addChangeListener (javax.swing.event.ChangeListener l);
	public abstract void removeChangeListener (javax.swing.event.ChangeListener l);
//	Public Instance Methods
	public abstract String getName ();

StyleConstants

Java 1.2

javax.swing.text

This class defines a number of standard attribute keys for commonly used character and paragraph attributes. It also defines a number of static convenience methods that use these attributes to query the value of an attribute from an AttributeSet or to set the value of an attribute in a MutableAttributeSet.

Usually, the type of the value to be associated with an attribute key is obvious from the context. The method signatures for the static get and set methods make the value explicit. The value associated with the Alignment key should be one of the four ALIGN_ constants defined by the class. Any length values associated with attributes such as LeftIndent and LineSpacing should be float values expressed in printer's points (there are 72 printer's points in one inch).

StyleConstants defines four inner subclasses, each of which implements a different marker interface that serves to group attribute keys into broad categories. These inner classes define attribute key constants as well, but these constants are also available directly from the StyleConstants class.

StyleContext

Java 1.2

javax.swing.text

serializable

This class is a collection of and a factory for Style objects. It is implemented in a way that allows caching and reuse of common attribute sets. Use addStyle() to create a new Style object and add it to the collection. Use the methods of the returned Style object to specify the attributes of the Style. Use getStyle() to look up a Style by name and removeStyle() to delete a Style from the collection. The static getDefaultStyleContext() method returns a default StyleContext object suitable for shared use by multiple documents. StyleContext also includes a simple Font cache. You can access shared Font instances with the getFont() method.

StyleContext also implements the AbstractDocument.AttributeContext interface, which means that it implements various methods for creating new AttributeSet objects by copying existing AttributeSet objects and adding or removing individual attributes. These methods make it possible to implement the MutableAttributeSet or Style interfaces in terms of immutable AttributeSet objects that can be cached and shared. The Style objects returned by addStyle() are instances of StyleContext.NamedStyle, which is implemented in this way. Styles that contain only a small number of attributes are implemented as immutable StyleContext.SmallAttributeSet objects that are cached and reused, resulting in significant memory savings.

StyleContext.SmallAttributeSet

Java 1.2

javax.swing.text

This immutable class implements the AttributeSet interface using a simple Object array, rather than a hashtable. This implementation is memory efficient and time efficient for small attribute sets.

StyledDocument

Java 1.2

javax.swing.text

This interface extends Document with the methods required for styled documents. A styled document allows attributes such as colors and font sizes to be applied to characters and runs of characters in the document. It also allows attributes such as margin sizes and line spacings to be applied to paragraphs. setCharacterAttributes() and setParagraphAttributes() apply a specified set of attributes to the specified region of the document. They can be used to augment or replace the existing attributes of that region. getCharacterElement() and getParagraphElement() return the Element object that most directly represents or contains the character or paragraph at the specified position.

The StyledDocument interface also defines methods for managing styles. A Style object is a named set of attributes, with an optional parent attribute set that is used to look up attributes that are not specified directly in the Style object. addStyle() creates a new Style object and registers it by name with the StyledDocument. getStyle() looks up a Style object by name. The intent of Style objects is to represent named paragraph types such as "heading," "blockquote," and so forth. The setLogicalStyle() method applies one of these named paragraph styles to the paragraph at the specified position. This is the default style for that paragraph, unless it is overridden by attributes specified with setCharacterAttributes() or setParagraphAttributes().

StyledEditorKit.ForegroundAction

Java 1.2

javax.swing.text

cloneable serializable

This action sets the color of the selected text or, if no text is selected, sets the color that is used for newly inserted text. The color to be used is specified when the ForegroundAction constructor is called. Or the color may be specified by the command string of the ActionEvent. In this case, the color string should be in a format that can be interpreted by the decode() method of java.awt.Color. StyledEditorKit does not include any objects of this type in the array of actions returned by its getAction() method.

TextAction

Java 1.2

javax.swing.text

cloneable serializable

This abstract class is an Action that extends AbstractAction. It does not implement any of the abstract methods of AbstractAction but merely adds new protected methods that subclasses can use to figure out on what JTextComponent they are supposed to operate. These methods allow subclasses to define generic actions that are not specific to a particular JTextComponent but that can be used on any text component. Applications may subclass this interface to define custom actions, but they do not often need to do so. DefaultEditorKit and StyledEditorKit define a number of inner classes that subclass TextAction.

public abstract class TextAction extends AbstractAction {
//	Public Constructors
	public TextAction (String name);
//	Public Class Methods
	public static final Action[ ] augmentList (Action[ ] list1, Action[ ] list2);
//	Protected Instance Methods
	protected final JTextComponent getFocusedComponent ();
	protected final JTextComponent getTextComponent (java.awt.event.ActionEvent e);
}

Utilities

Java 1.2

javax.swing.text

This class defines various static utility methods that are used internally by the javax.swing.text package. Although applications may occasionally find some of these methods useful, they are intended primarily for internal use and for use by programmers who are subclassing or heavily customizing javax.swing.text classes.

public class Utilities {
//	Public Constructors
	public Utilities ();
//	Public Class Methods
	public static final int drawTabbedText (Segment s, int x, int y, java.awt.Graphics g, TabExpander e, int startOffset);
	public static final int getBreakLocation (Segment s, java.awt.FontMetrics metrics, int x0, int x, TabExpander e, int startOffset);

View

Java 1.2

javax.swing.text

This class is the abstract superclass of a hierarchy of classes used to display various parts of a text document. Just as java.awt.Component is the root of the component hierarchy and has many subclasses in java.awt and javax.swing, View is the root of the view hierarchy and has many subclasses in javax.swing.text and javax.swing.text.html. Just as the various Component classes are used to display different GUI elements, the various View classes are used to display different types of document elements.

Each type of Document has a ViewFactory object that is used to create an appropriate View object for a given Element of a document. Because a Document consists of a tree of Element objects, the document is displayed using a tree of View objects. Just like GUI components, View objects are nested into a containment hierarchy. Thus, a BoxView might contain a TableView and several ParagraphView objects, each of which contains a number of PlainView objects interspersed with IconView objects.

Like a component, a View implementation must be able to paint itself, return its children, report its preferred size, and so on. In fact, you can think of a View as a kind of extremely lightweight component, with a number of methods analogous to Component methods. These include paint(), getView(), getViewCount(), getParent(), getPreferredSpan(), getMinimumSpan(), getMaximumSpan(), and isVisible().

A View implementation must also be able to convert between the document coordinate system--an integer position within the document--and the on-screen coordinate system in which things like mouse clicks and drags are measured. The viewToModel() and modelToView() methods are called to perform these conversions.

View objects are unlike components in one important aspect, however. They may be subject to word-wrapping and line breaking. The getBreakWeight() method returns an integer that specifies whether a given position is a reasonable place at which to insert a line break. If a View supports line breaking, its breakView() method should break the view into two and return the newly created View.

Programmers defining custom document types or custom document content types may need to create custom View implementations. Applications typically do not need to use or subclass this class directly.

ViewFactory

Java 1.2

javax.swing.text

The ViewFactory interface defines a basic create() method that creates View objects from the individual Element nodes of a Document. Different types of documents use different ViewFactory implementations to implement a custom Element to View mapping. The getViewFactory() method of EditorKit returns a ViewFactory for a particular document type.

public abstract interface ViewFactory {
//	Public Instance Methods
	public abstract View create (javax.swing.text.Element elem);
}
