hi,
I'm writing a simple app, i want the JTextArea size to change when the
frame size changes, i used ComponentListener and the componentResized
for the frame, the problem is i don't know which methods will change
the size of the JTextArea i tried resize(e.getComponent().getSize());
but it didn't work!.
thanks in advance

regards,

Use a layout manager, that is what they are for.

<sscce>
import java.awt.*;
import javax.swing.*;

class ResizableTextArea {
public static void main(String[] args) {
JFrame f = new JFrame( "Resizable TextArea" );
f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
Container c = f.getContentPane();
c.setLayout( new BorderLayout() );
c.add( new JScrollPane(
new JTextArea("Text Area", 5,20) ),
BorderLayout.CENTER );
c.add( new JButton("UP"), BorderLayout.NORTH );
c.add( new JTextField("DOWN"), BorderLayout.SOUTH );
c.add( new JLabel("L"), BorderLayout.WEST );
c.add( new JLabel("R"), BorderLayout.EAST );
f.pack();
f.setVisible(true);
}
}
</sscce>

Use layout managers instead.
