How to set default background color for JTextPane in Java?
To set the default background color of JTextPane, use the SimpleAttributeSet and StyleConstants class. At first, create a new JTextPane −
JTextPane pane = new JTextPane();
Now, use the classes to set the style and color −
SimpleAttributeSet attributeSet = new SimpleAttributeSet(); StyleConstants.setBackground(attributeSet, Color.white);
Now, apply the set to the pane −
pane.setCharacterAttributes(attributeSet, true);
The following is an example to set default background color for JTextPane −
Example
package my;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Container;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextPane;
import javax.swing.text.BadLocationException;
import javax.swing.text.SimpleAttributeSet;
import javax.swing.text.StyleConstants;
public class SwingDemo {
public static void main(String args[]) throws BadLocationException {
JFrame frame = new JFrame("Demo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Container container = frame.getContentPane();
JTextPane textPane = new JTextPane();
textPane.setBackground(Color.cyan);
SimpleAttributeSet attributeSet = new SimpleAttributeSet();
StyleConstants.setItalic(attributeSet, true);
StyleConstants.setForeground(attributeSet, Color.blue);
StyleConstants.setBackground(attributeSet, Color.white);
textPane.setCharacterAttributes(attributeSet, true);
textPane.setText("Updated the background color of the text pane.");
JScrollPane scrollPane = new JScrollPane(textPane);
container.add(scrollPane, BorderLayout.CENTER);
frame.setSize(550, 300);
