C++ (Cpp) QMenuBar::clear Examples

Example #1

File: qqmenuhelper.cpp Project: jmbowman/portabase

/**
 * <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>
