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

public class SplitPaneResizing extends JFrame implements PropertyChangeListener
{
	JSplitPane left;
	JSplitPane right;

	public SplitPaneResizing()
	{
		JSplitPane main = new JSplitPane();
		getContentPane().add( main );
		left = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
		right = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
		main.setLeftComponent( left );
		main.setRightComponent( right );
//
		left.setTopComponent( createPanel(Color.RED) );
		left.setBottomComponent( createPanel(Color.GREEN) );
		right.setTopComponent( createPanel(Color.BLUE) );
		right.setBottomComponent( createPanel(Color.WHITE) );
//
		left.addPropertyChangeListener( this );
		right.addPropertyChangeListener( this );
	}

	private JPanel createPanel(Color background)
	{
		JPanel panel = new JPanel();
		panel.setPreferredSize( new Dimension(200, 100) );
		panel.setBackground( background );
		return panel;
	}

	public void propertyChange(PropertyChangeEvent e)
	{
		if ("dividerLocation".equals(e.getPropertyName()))
		{
			Object source = e.getSource();
			JSplitPane target = (source.equals(left)) ? right : left;
			int location = ((Integer)e.getNewValue()).intValue();

			if (location != target.getDividerLocation())
				target.setDividerLocation( location );
		}
	}

	public static void main(String[] args)
	{
		SplitPaneResizing frame = new SplitPaneResizing();
		frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
		frame.pack();
		frame.setLocationRelativeTo( null );
		frame.setVisible(true);
	}
}

Hi Camickr

That was great help.
But can u help me in avoiding teat flickering that happens when I drag the horizontal divider ,which I havent observed while dragging the vertical divider.

Thank In Advance
Sharmila

I don't see any flicker with my example.

I have no idea what kind of components you have on your panels (I'm not a mind reader) so the only suggestion is to use the following method on your left/right splitPanes.:

setContinuousLayout(false);

Hi Camickr

Sorry , If I have explained the issue in another sense.
In SplitPaneResizing.java,we have explicitly made the dividers of the two SpliPanes (left and right) to map each other with respect to any change of the the other.

Due to this explict mapping we can find a little variation between the dividers of left and right dividers

hope you can help me out.

Addition to my code in reply 3. If you want continuous update of the divider location then you can use:

left.setContinuousLayout(true);
right.setContinuousLayout(true);
