This section lists commonly used parts of the API that are shared by text components. Much of this API is defined by the JTextComponent class. Text Component Features discusses how to use some of this API.
The JComponent Class describes the API that text components inherit from JComponent. For information about the API related to specific text components, see the how-to page for that component: text field, password field, formatted text field, text area, or editor pane and text pane.
For complete details about the text API, see the API documentation for JTextComponent and for the various classes and interfaces in the text package.
The API listed in this section includes the following categories:
JTextComponent) Cuts, copies, and pastes text using the system clipboard, or replaces the selected text with the string specified by an argument, respectively. EditorKit Provides a text component's view factory, document, caret, and actions, as well as reading and writing documents of a particular format. DefaultEditorKit A concrete subclass of EditorKit that provides the basic text editing capabilities. StyledEditorKit A subclass of Default EditorKit that provides additional editing capabilities for styled text. String xxxxAction
DefaultEditorKit) The names of all the actions supported by the default editor kit. See Associating Text Actions with Menus and Buttons. BeepAction
DefaultEditorKit) Inner classes that implement various text editing commands. AlignmentAction
StyledEditorKit) Inner classes that implement various editing commands for styled text. Action[] getActions()
JTextComponent) Gets the actions supported by this component. This method gets the array of actions from the editor kit if one is used by the component. InputMap getInputMap()
JComponent) Gets the input map that binds key strokes to actions. See Associating Text Actions with Key Strokes. void put(KeyStroke, Object)
InputMap) Binds the specified key to the specified action. You generally specify the action by its name, which for standard editing actions is represented by a string constant such as DefaultEditorKit.backwardAction. Classes and Interfaces That Represent Documents Interface or Class Description Document An interface that defines the API that must be implemented by all documents. AbstractDocument An abstract superclass implementation of the Document interface. This is the superclass for all documents provided by the Swing text package. PlainDocument A class that implements the Document interface. This is the default document for the plain text components (text field, password field, and text area). Additionally, this class is used by the editor panes and text panes when loading plain text or text of an unknown format. StyledDocument A Document subinterface. Defines the API that must be implemented by documents that support styled text. JTextPane requires that its document be of this type. DefaultStyledDocument A class that implements the StyledDocument interface. The default document for JTextPane. Reading and Writing Text Method Description void read(Reader, Object)
JTextComponent) Reads or writes text. void read(Reader, Document, int)
EditorKit) Reads text from a stream into a document. void write(Writer, Document, int, int)
EditorKit) Writes text from a document to a stream.
