If ApplicationWindow.showTopSeperator() returns false, the contents (as 
returned by createContents()) are reduced to a thin strip at the top of the 
shell.  Here's what I mean:


import org.eclipse.jface.window.ApplicationWindow;
import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.Color;
import org.eclipse.swt.graphics.Point;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Display;


public class DemonstrateAppWindowTopSeparatorProblem {

	public static void main(String[] args) {
		ApplicationWindow appWindow = new ApplicationWindow(null) {
			protected Control createContents(Composite parent) {
				Composite mainPanel = new Composite(parent, 
SWT.NONE);
				mainPanel.setLayout(new GridLayout(1, true));
				mainPanel.setBackground(new Color
(mainPanel.getDisplay(), 0, 0, 255));
				mainPanel.setLayoutData(new GridData
(GridData.FILL_BOTH));
				return mainPanel;
			}

			protected boolean showTopSeperator() {
				return false;
			}
			
			protected Point getInitialSize() {
				return new Point(400, 300);
			}
		};
		appWindow.setBlockOnOpen(true);
		appWindow.open();
		Display.getCurrent().dispose();
	}
}


It appears that the layout() method in ApplicationWindowLayout assumes the 
first child control of the shell will be the 'top separator', which isn't the 
case if showTopSeperator() return false.
