How to divide the composite into different spaces in SWT

Question

I am create a log viewer in SWT and I ran across a problem where I need to display the mainText and detailedText. I wants the mainText to have only 25% or available space and detailText should have 75% available space. So I went ahead and try to learn layout manager in swt mention here . Looks like SWT does not have any respective layout manger for me. I am currently using FillLayout which is simply diving the composite into equal space. Is there any way I can divide the space according to my convenience.

public class LogViewer{
 Text mainText;
 Text detailText;
 public void initialize(Composite parent){
  parent.setLayout(new FillLayout(SWT.VERTICAL));
  mainText = new Text( parent, SWT.WRAP | SWT.MULTI | SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL );
  detailText = new Text( parent, SWT.WRAP | SWT.MULTI | SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL );
  mainText.setVisible( true );
  detailText.setVisible( true );
  mainText.setText("This is the error message");
  detailText.setText("This text is mulitline error text message")
 }
}

This is how message is appearing

This is how I want

Could someone please help me and guide me in the right direction. Thanks in advance.

I would sincerely like to thanks greg-449. His comment made it possible. He suggested me to use org.eclipse.swt.custom.SashForm and it works perfectly. Thanks SO again. Here is my updated code.

public class LogViewer{
 Text mainText;
 Text detailText;
 public void initialize(Composite parent){
  parent.setLayout(new FillLayout(SWT.VERTICAL));
  SashForm sashForm =new SashForm(parent, SWT.VERTICAL);
  mainText = new Text( sashForm , SWT.WRAP | SWT.MULTI | SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL );
  detailText = new Text( sashForm , SWT.WRAP | SWT.MULTI | SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL );
  mainText.setVisible( true );
  detailText.setVisible( true );
  sashForm.setWeights(new int[]{1,3});
  mainText.setText("This is the error message");
  detailText.setText("This text is mulitline error text message")
 }
}
