Java program to insert a component into a JTextPane component
Let’s say the following is our JTextPane −
JTextPane textPane = new JTextPane(); textPane.setForeground(Color.white); textPane.setBackground(Color.blue);
Now, set the style and attributes. Also, set the font −
SimpleAttributeSet attributeSet = new SimpleAttributeSet();
StyleConstants.setItalic(attributeSet, true);
textPane.setCharacterAttributes(attributeSet, true);
textPane.setText("Press the Button ");
Font font = new Font("Verdana", Font.BOLD, 22);
textPane.setFont(font);After the text displayed above, we will insert a component using setComponent() −
StyledDocument doc = (StyledDocument) textPane.getDocument();
Style style = doc.addStyle("StyleName", null);
StyleConstants.setComponent(style, new JButton("Submit"));
doc.insertString(doc.getLength(), "invisible text", style);The following is an example to insert a component into a component. Here, we have set a button component inside a JTextPane −
Example
package my;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Container;
import java.awt.Font;
import javax.swing.JButton;
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.Style;
import javax.swing.text.StyleConstants;
import javax.swing.text.StyledDocument;
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.setForeground(Color.white);
textPane.setBackground(Color.blue);
SimpleAttributeSet attributeSet = new SimpleAttributeSet();
StyleConstants.setItalic(attributeSet, true);
textPane.setCharacterAttributes(attributeSet, true);
textPane.setText("Press the Button ");
Font font = new Font("Verdana", Font.BOLD, 22);
textPane.setFont(font);
StyledDocument doc = (StyledDocument) textPane.getDocument();
Style style = doc.addStyle("StyleName", null);
StyleConstants.setComponent(style, new JButton("Submit"));
doc.insertString(doc.getLength(), "invisible text", style);
JScrollPane scrollPane = new JScrollPane(textPane);
scrollPane = new JScrollPane(textPane);
container.add(scrollPane, BorderLayout.CENTER);
frame.setSize(550, 300);
frame.setVisible(true);
}
}Output
