What is a Sash form?
write code, try something and then post your SSCCE. Then, we can help.

Thanks for your replay. please fallow the below code is the sample example

package test;

import org.eclipse.swt.SWT;

/**
* This class demonstrates SashForm
*/
public class SashFormTest {
   public SashForm sashForm,sashForm_1,sashForm_2;

/**
    * Runs the application
    */
   public void run() {
      Display display = new Display();
      Shell shell = new Shell(display);
      shell.setText("SashForm Test");
      createContents(shell);
      shell.open();

// This is the part, where the children of SashForm are printed out:
      final Control[] controls = sashForm.getChildren();
      SashForm s1=(SashForm)controls[0];
      SashForm s2=(SashForm)controls[1];
      s1.addControlListener(new ControlListener() {
		
		@Override
		public void controlResized(ControlEvent arg0) {
			// TODO Auto-generated method stub
		System.out.println("control resizing 1");	
		}
		
		@Override
		public void controlMoved(ControlEvent arg0) {
			// TODO Auto-generated method stub
			System.out.println("control moving 1");
		}
	});
      s2.addControlListener(new ControlListener() {
  		
  		@Override
  		public void controlResized(ControlEvent arg0) {
  			// TODO Auto-generated method stub
  		System.out.println("control resizing 2");	
  		}
  		
  		@Override
  		public void controlMoved(ControlEvent arg0) {
  			// TODO Auto-generated method stub
  			System.out.println("control moving 2");
  		}
  	});
      
      
      while (!shell.isDisposed()) {
         if (!display.readAndDispatch()) {
            display.sleep();
         }
      }
      display.dispose();
   }

/**
    * Creates the main window's contents
    *
    * @param parent
    *            the parent window
    */
   private void createContents(Composite parent) {
      // Fill the parent window with the buttons and sash
      parent.setLayout(new FillLayout());

// Create the SashForm and the buttons
      sashForm = new SashForm(parent, SWT.HORIZONTAL);
      sashForm.setOrientation(SWT.VERTICAL);
      
      sashForm_1 = new SashForm(sashForm, SWT.NONE);
      
      Button btnNewButton_1 = new Button(sashForm_1, SWT.NONE);
      btnNewButton_1.setText("New Button");
      
      Button btnNewButton = new Button(sashForm_1, SWT.NONE);
      btnNewButton.setText("New Button");
      sashForm_2 = new SashForm(sashForm, SWT.NONE);
      
      Button btnNewButton_2 = new Button(sashForm_2, SWT.NONE);
      btnNewButton_2.setText("New Button");
      
      Button btnNewButton_3 = new Button(sashForm_2, SWT.NONE);
      btnNewButton_3.setText("New Button");
      sashForm_2.setWeights(new int[] {1, 1});
      sashForm_1.setWeights(new int[] {1, 1});
      sashForm.setWeights(new int[] {217, 214});
   }

/**
    * The application entry point
    *
    * @param args
    *            the command line arguments
    */
   public static void main(String[] args) {
      new SashFormTest().run();
   }
}

the above source code is the example of my problem. when i changing the sashForm_1 weights automatically it has to change the sashForm_2 weights with listeners. is there any possible please help me

Can you please UseCodeTags next time? Not only will it be easier to read, it also removed the necessity to use a larger font size.

Please help me.....I given the source code above ...Please help me......
How to re-size the weights of the both child sash forms at time either vertically or horizontally .

KeepItDown. Don't ever use such a large font size again. It only annoys people.

If you don't get replies, perhaps it's because nobody knows the answer?
