 * @param parent
 *            The parent shell.
 * @param shellStyle
 *            The shell style.
 * @param takeFocusOnOpen
 *            A boolean indicating whether focus should be taken by this
 *            popup when it opens.
 * @param persistSize
 *            A boolean indicating whether the size should be persisted upon
 *            close of the dialog. The size can only be persisted if the
 *            dialog settings for persisting the bounds are also specified.
 *            If a menu action will be provided that allows the user to
 *            control this feature and the user hasn't changed that setting,
 *            then this flag is used as initial default for the menu.
 * @param persistLocation
 *            A boolean indicating whether the location should be persisted
 *            upon close of the dialog. The location can only be persisted
 *            if the dialog settings for persisting the bounds are also
 *            specified. If a menu action will be provided that allows the
 *            user to control this feature and the user hasn't changed that
 *            setting, then this flag is used as initial default for the
 *            menu. default for the menu until the user changed it.
 * @param showDialogMenu
 *            A boolean indicating whether a menu for moving and resizing
 *            the popup should be provided.
 * @param showPersistActions
 *            A boolean indicating whether actions allowing the user to
 *            control the persisting of the dialog bounds and location
 *            should be shown in the dialog menu. This parameter has no
 *            effect if <code>showDialogMenu</code> is <code>false</code>.
 * @param titleText
 *            Text to be shown in an upper title area, or <code>null</code>
 *            if there is no title.
 * @param infoText
 *            Text to be shown in a lower info area, or <code>null</code>
 *            if there is no info area.
 * @param use34API
 *            <code>true</code> if 3.4 API should be used
 * 
 * @see PopupDialog#getDialogSettings()

 * @since 1.1
