The insert(String str, int pos)
of the JTextArea
allows us to insert a text at the specified position. In the example below we insert brown and over words into the current JTextArea
text.
package org.kodejava.swing;
import javax.swing.*;
import java.awt.*;
public class TextAreaInsertText extends JPanel {
public TextAreaInsertText() {
initializeUI();
}
public static void showFrame() {
JPanel panel = new TextAreaInsertText();
panel.setOpaque(true);
JFrame frame = new JFrame("JTextArea Demo");
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.setContentPane(panel);
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(TextAreaInsertText::showFrame);
}
private void initializeUI() {
String text = "The quick fox jumps the lazy dog.";
JTextArea textArea = new JTextArea(text);
textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);
JScrollPane scrollPane = new JScrollPane(textArea);
textArea.insert("brown ", 10);
textArea.insert("over ", 26);
this.setPreferredSize(new Dimension(500, 200));
this.setLayout(new BorderLayout());
this.add(scrollPane, BorderLayout.CENTER);
}
}
