How to set style for JTextPane in Java?

To set style for text in JTextPane, use setItalic() or setBold() that sets italic or bold style for font respectively.

Following is our JTextPane component −

JTextPane pane = new JTextPane();

Now, use the StyleConstants class to set style for the JTextPane we created above. We have also set the background and foregound color −

SimpleAttributeSet attributeSet = new SimpleAttributeSet();
StyleConstants.setItalic(attributeSet, true);
StyleConstants.setForeground(attributeSet, Color.black);
StyleConstants.setBackground(attributeSet, Color.orange);
pane.setCharacterAttributes(attributeSet, true);

The following is an example to set style 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 pane = new JTextPane();
      SimpleAttributeSet attributeSet = new SimpleAttributeSet();
      StyleConstants.setItalic(attributeSet, true);
      StyleConstants.setForeground(attributeSet, Color.black);
      StyleConstants.setBackground(attributeSet, Color.orange);
      pane.setCharacterAttributes(attributeSet, true);
      pane.setText("We are learning Java and this is a demo text!");
      JScrollPane scrollPane = new JScrollPane(pane);
      container.add(scrollPane, BorderLayout.CENTER);
      frame.setSize(550, 300);
      frame.setVisible(true);
   }
}
