Scroll within a tableItem [message #532566]

I have a tableItem which its control extends the size of the screen, but I can't get to add a scroll. I was able to add a scroll, but it didn't reach the the end of the tableItem. I wrote a short program which illustrates the problem (my code is much more complex and I use a lot of layers).
The example includes a tabFolder with a single tabItem. I added a grid layout with 5 labels. When I shrink the dialog, I can't see the right end of the strings.
here is the code:

import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.CTabFolder;
import org.eclipse.swt.custom.CTabItem;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.ui.PlatformUI;

public class SimulateView {

	static public void main(){
		Shell m_shell;
		Display display = PlatformUI.getWorkbench().getDisplay();
		m_shell = new Shell(display, SWT.SHELL_TRIM /*| SWT.SCROLL_LINE/*| SWT.H_SCROLL | SWT.CLIP_CHILDREN | SWT.CLIP_SIBLINGS*/ /*| SWT.SCROLL_PAGE*/);
		m_shell.setText("Simulation");
		FillLayout flayout = new FillLayout(SWT.FILL);
		flayout.marginHeight = 0;
		flayout.marginWidth = 5;
		m_shell.setLayout(flayout);
		//create the tab folder
		CTabFolder tab = new CTabFolder(m_shell, SWT.TOP );
		//create the tab item
		CTabItem item = new CTabItem(tab, SWT.RESIZE | SWT.H_SCROLL);
		item.setText("tab Item");
		//create the top 3 labels
		Composite topcomposite = new Composite(tab, SWT.RESIZE | SWT.SCROLL_PAGE);
		topcomposite.setLayout(new GridLayout(5, true));

		new Label(topcomposite, SWT.NONE).setText("first Lable ");
		new Label(topcomposite, SWT.NONE).setText("            ");
		new Label(topcomposite, SWT.NONE).setText("second Lable");
		new Label(topcomposite, SWT.NONE).setText("            ");
		new Label(topcomposite, SWT.NONE).setText("third Lable ");
		item.setControl(topcomposite);
		m_shell.open();
	}
}

I couldn't figure out how to add a PNG of my dialog.
Thanks,
Nir

You need to use a ScrolledComposite inside the TabItem.
