Hi,
I am writing an application to show a scroll panel attached to a text area
but it does not appear on the screen. If remove the lines

JScrollPane scrollText = new JScrollPane(textArea);
contentPane.add(scrollText);

and add

contentPane.add(textField)

It appears but without scroll?.


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

class TestFrame extends JFrame {
private JTextArea textArea;

public static void main(String[] args) {
TestFrame frame = new TestFrame();
frame.setVisible(true);
}

public TestFrame( ) {

setSize ( 700, 400 );
setLocation ( 5, 5 );

Container contentPane = getContentPane();
contentPane.setBackground(Color.white);
contentPane.setLayout(null);

textArea = new JTextArea();
textArea.setEditable(false);
textArea.setBounds(350, 50, 100, 135);
textArea.setBorder(BorderFactory.createLineBorder(Color.red));
JScrollPane scrollText = new JScrollPane(textArea);
contentPane.add(scrollText);

}



}
