How to create a window with 3 tabs in JAVA SWT?

Hi,
I just started to work with JAVA SWT package.

Can you please send me a sample code which creates a window that has 3 tabs in it by using swt package?

And the tab names will be A, B and C.

import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;

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

        shell.setLayout(new GridLayout());
        // SWT.BOTTOM to show at the bottom
        CTabFolder folder = new CTabFolder(shell, SWT.BOTTOM);
        GridData data = new GridData(GridData.FILL, 
                GridData.FILL, true, true,
                2, 1);
        folder.setLayoutData(data);
        CTabItem cTabItem1 = new CTabItem(folder, SWT.NONE);
        cTabItem1.setText("Tab1");
        CTabItem cTabItem2 = new CTabItem(folder, SWT.NONE);
        cTabItem2.setText("Tab2");
        CTabItem cTabItem3 = new CTabItem(folder, SWT.NONE);
        cTabItem3.setText("Tab3");

        Text text = new Text(folder, SWT.BORDER);
        text.setText("Hello");
        cTabItem1.setControl(text);

        shell.pack();
        shell.open();
        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }
    }

How can I move these tab to the top left corner of the page?

 and is there a way to set the size of the initial window to a certain value?

Actually, the thing that I try to create looks like the one in the attachment.

without digging into the API it looks like you could replace SWT.BOTTOM with SWT.TOP

API reference can be found here:

http://www.eclipse.org/swt/docs.php

if you can't locate it I can do search through it.

Ok. I made the tabs on the top. Now, how can I create the icons in the first tab as shown in the mock up that I sent?
this should help you understand how that works.

http://www.eclipse.org/articles/article.php?file=Article-Understanding-Layouts/index.html

Do you have a good IDE that you are able to test in?  

it helps to tinker and see what the different options can do and how they work.

Ok. Now I managed to add the button but I cannot generate the tabs anymore.

What am I missing?
