Listing 1. This simple Hello World application shows the basic layout of an SWT application.

package com.develop;

import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;

public class HelloWorld
{
  public static void main(String[] args)
  {
    Display display = new Display();

    Shell shell = new Shell(display);
    shell.setText("Hello World Application");
    shell.setBounds(20, 20, 300, 100); 

    Label label = new Label(shell, SWT.CENTER); 
    label.setText("Hello World");
    label.setBounds(shell.getClientArea());

    shell.layout();
    shell.open();

    while(!shell.isDisposed())
      if(!display.readAndDispatch())
        display.sleep();

    display.dispose();
  }
}
