All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible, Scrollable, Targetable

public class JXEditorPane
extends JEditorPane
implements Targetable

JXEditorPane offers enhanced functionality over the standard JEditorPane.

Additional Features

Improved text editing

The standard text component commands for cut, copy, and paste used enhanced selection methods. The commands will only be active if there is text to cut or copy selected or valid text in the clipboard to paste.

Improved HTML editing

Using the context-sensitive approach for the standard text commands, JXEditorPane provides HTML editing commands that alter functionality depending on the document state. Currently, the user can quick-format the document with headers (H# tags), paragraphs, and breaks.

Built-in UndoManager

Text components provide UndoableEditEvents. JXEditorPane places those events in an UndoManager and provides undo/redo commands. Undo and redo are context-sensitive (like the text commands) and will only be active if it is possible to perform the command.

Built-in search

Using SwingX search mechanisms, JXEditorPane provides search capabilities, allowing the user to find text within the document.

Example

Creating a JXEditorPane is no different than creating a JEditorPane. However, the following example demonstrates the best way to access the improved command functionality.

 JXEditorPane editorPane = new JXEditorPane("some URL");
 add(editorPane);
 JToolBar toolBar = ActionContainerFactory.createToolBar(editorPane.getCommands[]);
 toolBar.addSeparator();
 toolBar.add(editorPane.getParagraphSelector());
 setToolBar(toolBar);
