What are the differences between a JTextPane and a JEditorPane in Java?
A JTextPane is an extension of JEditorPane which provides word processing features like fonts, text styles, colors and etc. If we need to do heavy-duty text processing we can use this class whereas a JEditorPane supports display/editing of HTML and RTF content and can be extended by creating our own EditorKit.
JTextPane
- A JTextPane is a subclass of JEditorPane.
- A JTextPane is used for a styled document with embedded images and components.
- A JTextPane is a text component that can be marked up with the attributes that are represented graphically and it can use a DefaultStyledDocument as the default model.
- The important methods of JTextPane are addStyle(), getCharacterAttributes(), getStyledDocument(), setDocument(), setEditorKit(), setStyledDocument() and etc.
Example
import java.awt.*;
import javax.swing.*;
import javax.swing.text.*;
public class JTextPaneTest {
public static void main(String args[]) throws BadLocationException {
JFrame frame = new JFrame("JTextPane Test");
Container cp = frame.getContentPane();
JTextPane pane = new JTextPane();
SimpleAttributeSet set = new SimpleAttributeSet();
StyleConstants.setBold(set, true);
pane.setCharacterAttributes(set, true);
pane.setText("Welcome to");
set = new SimpleAttributeSet();
StyleConstants.setItalic(set, true);
StyleConstants.setForeground(set, Color.blue);
Document doc = pane.getStyledDocument();
doc.insertString(doc.getLength(), " Tutorials ", set);
set = new SimpleAttributeSet();
StyleConstants.setFontSize(set, 20);
doc.insertString(doc.getLength(), " Point", set);
JScrollPane scrollPane = new JScrollPane(pane);
cp.add(scrollPane, BorderLayout.CENTER);
frame.setSize(375, 250);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
}Output
JEditorPane
- A JEditorPane is a kind of text area which can display various text formats
- By default, JEditorPane supports HTML and RTF (Rich Text Format), we can build our own editor kits to handle a specific content type.
- We can use setContentType() method to choose the document we want to display and setEditorKit() method to set custom editor for JEditorPane explicitly.
Example
import javax.swing.*;
public class JEditorPaneTest extends JFrame {
public JEditorPaneTest() {
setTitle("JEditorPane Test");
JEditorPane editorPane = new JEditorPane();
editorPane.setContentType("text/html");
editorPane.setText("<h1>Java</h1><p>is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.</p>");
setSize(350, 275);
setContentPane(editorPane);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLocationRelativeTo(null);
setVisible(true);
}
public static void main(String[] a) {
new JEditorPaneTest();
}
}Output
