示例1: updateDocumentFileMenu
/**
* <p>Adjust the "File" menu and toolbar contents as appropriate for the
* document screen. Sets the "File" menu to have the following content:</p>
* <ul>
* <li>Save</li>
* <li>(items added using addToFileMenu() go here)</li>
* <li><i>(separator)</i></li>
* <li>Close</li>
* <li>Preferences</li>
* <li><i>(separator)</i></li>
* <li>Quit</li>
* </ul>
* <p>Also shows the "Save" button on the toolbar. If creating
* a new file which isn't automatically saved, follow this with a call
* to setEdited(true). On the Mac, also shows a document icon in the
* titlebar. This method should be called after the visibility of any
* application-specific actions has been updated (due to a Maemo
* implementation detail).</p>
