	/**
	 * The <code>PopupDialog</code> implementation of this <code>Window</code>
	 * method creates and lays out the top level composite for the dialog. It
	 * then calls the <code>createTitleMenuArea</code>,
	 * <code>createDialogArea</code>, and <code>createInfoTextArea</code>
	 * methods to create an optional title and menu area on the top, a dialog
	 * area in the center, and an optional info text area at the bottom.
	 * Overriding <code>createDialogArea</code> and (optionally)
	 * <code>createTitleMenuArea</code> and <code>createTitleMenuArea</code>
	 * are recommended rather than overriding this method.
