Hi,can someone tell me why my code marked red below doesn't work?

 

 

 

public class LayoutDataTest {

 

   public static void main(String[] args) {

 

       Display display = new Display();

 

       Shell shell = new Shell(display);

 

       // Create the layout.

 

       GridLayout layout = new GridLayout();
      

       // Optionally set layout fields.

 

       // Set the layout into the composite.

 

       shell.setLayout(layout);

 

       // Create the children of the composite.

 

       Button button1 = new Button(shell, SWT.PUSH);
       button1.setText("Button1");
       button1.setSize(30,10);

 

       shell.pack();

 

       shell.open();

 

       while (!shell.isDisposed()) {

 

          if (!display.readAndDispatch()) display.sleep();

 

       }

 

   }

 

}

 

 

 

Thanks,
