Bug 34445 Reverse sort for AddressBook example
When you click on the header for a column in the AddressBook example, it sorts the selected column. It would be nice if selecting it again reversed the sort as most client applications would.

subItem = new MenuItem(menu, SWT.NULL);
	subItem.setText(resAddressBook.getString("Open_address_book"));
	subItem.setAccelerator(SWT.MOD1 + 'O');
	subItem.addSelectionListener(new SelectionAdapter() {
		public void widgetSelected(SelectionEvent e) {
			if (closeAddressBook()) {
				openAddressBook();
			}
		}
	});
	
	subItem = new MenuItem(menu, SWT.NULL);
	subItem.setText(resAddressBook.getString("Save_address_book"));
	subItem.setAccelerator(SWT.MOD1 + 'S');
	subItem.addSelectionListener(new SelectionAdapter() {
		public void widgetSelected(SelectionEvent e) {
			save();
		}
	});
