[SOLVED] Java JTextPane

Martin_J · 02-07-2010, 03:35 AM

Hello, please can someone show me code to make my JTextArea scrollable ?
I used this code but it doesn't scroll just expand my JTextArea out of JFrame.
Part of code I used(one that doesn't work):

Quote:

public class GraphicsDemo {
public GraphicsDemo {
/*Previous code*/
JFrame frame = new JFrame("New Frame");
JPanel panel = new JPanel();

output = new JTextArea(5,30);
output.setEditable(false);
JScrollPane scrollPane = new JScrollPane(output);

panel.add(output);
panel.add(scrollPane);
frame.add(panel);
frame.setVisible(true);
frame.setSize(300,300);
}
}

Similar code is in in Java 6 Official Tutorial

Code:

import javax.swing.*;
import java.awt.BorderLayout;

public class GraphicsDemo {
  public GraphicsDemo (){
    /*Previous code*/
    JFrame frame = new JFrame("New Frame");
   
    JTextArea jTextArea = new JTextArea( 30, 50 );
    JScrollPane jScrollPane = new JScrollPane( jTextArea );
    
    frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
    frame.setSize( 300, 300);
    frame.add( jScrollPane, BorderLayout.CENTER );
    frame.setVisible( true );
   
    
  }
  
  public static void main(String[] args){
      new GraphicsDemo(); 
  }
}
