public class MyProBar {
public static void main(String[] args){
final Display display = Display.getDefault();

shell.setSize(200, 100);
shell.setText("MyProgressBar");
shell.setLayout(new FillLayout());
final ProgressBar MyBar = new ProgressBar(shell,SWT.SMOOTH);
MyBar.setMinimum(0);
MyBar.setMaximum(100);

new Thread(){

try {
Thread.sleep(100);
} catch (InterruptedException e) {

shell.layout();
shell.open();
while(!shell.isDisposed()){
if(!display.readAndDispatch()){
