[news.eclipse.platform] Adding Scrollable on Group Page

[cool.calm.akash@xxxxxxxxx (akash)]

Hi,

I am adding a WizardPage on a Wizard. 
public clas tempWizard{
public void addPages() {
		try {
			mainPage = new TempPage(workbench, selection);
			super.addPage(mainPage);
		} catch (Throwable e) {
		}
	}
}
public class TempPage {

public void createControl(Composite parent) {
		Composite composite = new Composite(parent, SWT.None);

		composite.setLayout(new GridLayout());
		composite.setLayoutData(new GridData(GridData.VERTICAL_ALIGN_FILL
				| GridData.HORIZONTAL_ALIGN_FILL));
		composite.setFont(parent.getFont());
		setControl(composite);
		Group group = new Group(composite, SWT.None);
		group.setLayout(new GridLayout());
		group.setText("Buttons"); //$NON-NLS-1$
		group.setLayoutData(new GridData(GridData.GRAB_HORIZONTAL
				| GridData.HORIZONTAL_ALIGN_FILL)); 
		for (int count = 0; count < 100; count++) {
			Button sectionCheckbox = new Button(group, SWT.CHECK);
			arrayList.add(sectionCheckbox);
			sectionCheckbox.setText("Button"); //$NON-NLS-1$
			sectionCheckbox.setSelection(false);
			sectionCheckbox.addListener(SWT.Selection, this);
		}
}
}

As u see i m adding some 100 buttons onto the page. My requireement is to 
set some predefined height for the WizardPage or Wizard and if buttons 
exceed the same to display a scrollbar so taht all the buttons can be seen.
Can anyone please suggest any way to achieve the same.? Thanking in 
advance,

Regards,
