You add - menu items with \link TQMenuData::insertItem() - insertItem()\endlink. For example, asuming that \c menubar is a - pointer to a TQMenuBar and \c filemenu is a pointer to a - TQPopupMenu, the following statement inserts the menu into the menu - bar: - \code - menubar->insertItem( "&File", filemenu ); - \endcode - The ampersand in the menu item's text sets Alt+F as a shortcut for - this menu. (You can use "\&\&" to get a real ampersand in the menu - bar.) - - Items are either enabled or disabled. You toggle their state with - setItemEnabled(). - - There is no need to lay out a menu bar. It automatically sets its - own tqgeometry to the top of the parent widget and changes it - appropriately whenever the parent is resized. - - \important insertItem removeItem clear insertSeparator setItemEnabled isItemEnabled setItemVisible isItemVisible - - Example of creating a menu bar with menu items (from \l menu/menu.cpp): - \quotefile menu/menu.cpp - \skipto file = new TQPopupMenu - \printline - \skipto Qt::Key_O - \printline - \printline - \skipto new TQMenuBar - \printline - \skipto insertItem - \printline - - In most main window style applications you would use the menuBar() - provided in TQMainWindow, adding \l{TQPopupMenu}s to the menu bar - and adding \l{TQAction}s to the popup menus. - - Example (from \l action/application.cpp): - \quotefile action/application.cpp - \skipto file = new TQPopupMenu - \printuntil fileNewAction - - Menu items can have text and pixmaps (or iconsets), see the - various \link TQMenuData::insertItem() insertItem()\endlink - overloads, as well as separators, see \link - TQMenuData::insertSeparator() insertSeparator()\endlink. You can - also add custom menu items that are derived from - \l{TQCustomMenuItem}. - - Menu items may be removed with removeItem() and enabled or - disabled with \link TQMenuData::setItemEnabled() - setItemEnabled()\endlink. - - <img src=qmenubar-m.png> <img src=qmenubar-w.png> - - \section1 TQMenuBar on TQt/Mac - - TQMenuBar on TQt/Mac is a wrapper for using the system-wide menubar. - If you have multiple menubars in one dialog the outermost menubar - (normally inside a widget with widget flag \c WType_TopLevel) will - be used for the system-wide menubar. - - Note that arbitrary TQt widgets \e cannot be inserted into a - TQMenuBar on the Mac because TQt uses Mac's native menus which don't - support this functionality. This limitation does not apply to - stand-alone TQPopupMenus. - - TQt/Mac also provides a menubar merging feature to make TQMenuBar - conform more closely to accepted Mac OS X menubar tqlayout. The - merging functionality is based on string matching the title of a - TQPopupMenu entry. These strings are translated (using - TQObject::tr()) in the "TQMenuBar" context. If an entry is moved its - Q_SLOTS will still fire as if it was in the original place. The - table below outlines the strings looked for and where the entry is - placed if matched: - - \table - \header \i String matches \i Placement \i Notes - \row \i about.* - \i Application Menu | About <application name> - \i If this entry is not found no About item will appear in - the Application Menu - \row \i config, options, setup, settings or preferences - \i Application Menu | Preferences - \i If this entry is not found the Settings item will be disabled - \row \i quit or exit - \i Application Menu | Quit <application name> - \i If this entry is not found a default Quit item will be - created to call TQApplication::quit() - \endtable - - \link menu-example.html menu/menu.cpp\endlink is an example of - TQMenuBar and TQPopupMenu use. - - \sa TQPopupMenu TQAccel TQAction \link http://developer.apple.com/techpubs/macosx/Carbon/HumanInterfaceToolbox/Aqua/aqua.html Aqua Style Guidelines \endlink \link guibooks.html#fowler GUI Design Handbook: Menu Bar \endlink -*/ - - -/*! - \enum TQMenuBar::Separator - - This enum type is used to decide whether TQMenuBar should draw a - separator line at its bottom. - - \value Never In many applications there is already a separator, - and having two looks wrong. - - \value InWindowsStyle In some other applications a separator looks - good in Windows style, but nowhere else. -*/ - -/*! - \fn void TQMenuBar::activated( int id ) - - This signal is emitted when a menu item is selected; \a id is the - id of the selected item. - - Normally you will connect each menu item to a single slot using - TQMenuData::insertItem(), but sometimes you will want to connect - several items to a single slot (most often if the user selects - from an array).
