Resizing Panels inside a Jframe ??

[jay vas]

Hi Guys :

Im having trouble figuring out how to resize INTERNAL panels in a jframe.

I know that in swt, this can be done using a "sash form". But is this
possible in Java Swing ?

Please let me know !!!

Thanks - j

import java.awt.*;
import javax.swing.*;
import javax.swing.event.*;
 
public class Resizing implements ChangeListener
{
    JPanel panel;
 
    public void stateChanged(ChangeEvent e)
    {
        JSlider slider = (JSlider)e.getSource();
        int value = slider.getValue();
        Dimension d = new Dimension(value, value);
        panel.setPreferredSize(d);
        panel.revalidate();
    }
 
    private JPanel getPanel()
    {
        panel = new JPanel();
        panel.setPreferredSize(new Dimension(200,200));
        panel.setBackground(Color.red);
        JPanel parent = new JPanel(new GridBagLayout());
        GridBagConstraints c = new GridBagConstraints();
        parent.add(panel, c);
        return parent;
    }
 
    private JSlider getSlider()
    {
        JSlider slider = new JSlider(JSlider.HORIZONTAL, 50, 500, 200);
        slider.addChangeListener(this);
        return slider;
    }
 
    public static void main(String[] args)
    {
        Resizing test = new Resizing();
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(new JScrollPane(test.getPanel()));
        f.getContentPane().add(test.getSlider(), "South");
        f.setSize(400,400);
        f.setLocation(200,200);
        f.setVisible(true);
    }
}

Hi Thanks, but Im talking more about resizeable "frames"
inside of a JFrame that the user can resize at will.

This is called a sash form in SWT, or a "Frame" in the web browser
world.

any ideas ?

If so, Im all out, so please help !
